To disable a channel so that it is not selectable, choose the conven-tional type and do not check this box.Copy Parameters From Channel - If another channel is selected in the box, the parameters from that channel are copied to the new channel.Channel TypeChannel Type Box - Selects the specific system from which the channel is selected. All programmed systems are displayed by number and type (conven-tional, SMARTNET, SmartZone). When a different channel type is selected, the screen for that type of channel is automatically displayed. Other Screen ParametersSystem Specific Information - With SMARTNET/SmartZone systems, indicates the system ID programmed on the system General screen (seeSection 3.6.2).Talk Group - Selects the talk group selected by that channel. Talk groups are programmed in the Talk Group screen described in Section 3.6.5.Announcement Group - Selects one of up to three announcement groups selected by the channel. Refer to “Announcement Group Screen” in Section 3.6.7 for more information.Emergency Group - Selects the talk group used for emergency calls.Talk Permit Tone - When enabled, a short tone sounds after a request for a group call has been approved by the main controller. This indicates that speaking can begin. When disabled, no audio feed-back is used to indicate when speaking can begin.System Scan - Selects the Priority Monitor Scan list selected by the channel (see “Priority Monitor Scan Screen” description in Section 3.6.7). If “No Scan List” is programmed, scanning is not selectable on that channel.Auto Scan - When enabled and a channel is selected, the radio automatically begins scanning the scan list associated with that channel. When disabled, scan-ning can only be started manually by the Scan option switch.3.7 PASSWORD OPERATION3.7.1 GENERALThe 50xx portable radio can be programmed with a Power-Up and Programming password. If the Power-Up password is enabled, it must be entered each time power is turned on to make the radio operational. This prevents unauthorized use. The Programming pass-word must be entered to access the keypad program-ming feature of the radio. This prevents unauthorized reprogramming of the transceiver. Currently, the 50xx portable is the only transceiver that is programmed with the PCTrunk software that utilizes password access. More information on these two passwords follows.3.7.2 POWER-UP PASSWORDThe Power-Up password function is enabled on the Radio-Wide General screen described in Section 3.4.2. This password must then be entered each time transceiver power is turned on. In addition, since the radio resets after downloading or uploading data, it must be entered after performing those functions (see Sections 3.3.3 and 3.3.4). When entering the pass-word using the radio keypad, enter the eight password digits and then press the ENT key. If an error is made, press the CLR key to start over.To enable the power-up password function on the programmer screen, the Power-Up password must be entered. This prevents the radio from being programmed with an unknown password which would make it inoperable. The password is a series of eight numbers, and it is programmed by clicking the “Change Password” button on the Radio-Wide General screen. The default password is eight zeros (00000000), and it may need to be entered as the “old” password if applicable. The password can also be
TRANSCEIVER PROGRAMMING3-29 September 2001Part No. 001-5100-001changed using the radio keypad when the keypad is locked by entering the old password and then pressing the # key. Refer to Section 2.4.3 for more information.If the Power-Up password has been enabled in the radio connected to the programmer, the Programming password described in the next section must then be entered before a data can be downloaded or uploaded. This prevents an unauthorized person from reading radio data or changing radio programming.If the password is forgotten, it can be overridden by pressing the lower button on the side 8 times. This unlocks the radio and reverts to the default password of “00000000”. However, it also erases all channel frequencies, trunked group IDs, and encryption infor-mation. Therefore, the radio must be reprogrammed after this is done to make it operational again.3.7.3 PROGRAMMING PASSWORDThe Programming password must be entered to enable the Keypad Programming mode described in Section 2.9.

4-1 September 2001Part No. 001-5100-001CIRCUIT DESCRIPTIONSECTION 4 CIRCUIT DESCRIPTION4.1 GENERAL OVERVIEW4.1.1 INTRODUCTIONThe E.F Johnson 5100 series digital portable radio is a microcontroller-based radio that uses a Digital Signal Processor (DSP) to provide the following modes of operation:Narrowband Analog - FM modulation with a maximum deviation of 2.5 kHz. This mode is usually used in systems where the channel spacing is 12.5 kHz. Call Guard (CTCSS or DCS) subaudible squelch signaling can be used in this mode.Wideband Analog - FM modulation with a maximum deviation of 5 kHz. This mode is usually used in systems where the channel spacing is 25 kHz or 30 kHz. Call Guard (CTCSS or DCS) subaudible squelch signaling can be used in this mode.Project 25 Digital - The voice is digitized, error corrected, optionally encrypted and transmitted using C4FM modulation according to the Project 25 stan-dard. This mode can be used in channel spacings of 12.5 kHz.The DSP processes the received signals and generates the appropriate output signals. The micro-controller controls the hardware and provides an inter-face between hardware and DSP.PC BoardsThis radio contains the following PC boards:•RF Board•Digital Board•Keypad Board•Four flex circuits that provide interconnection and support for the volume, on/off, and LED controls.•Encryption board (optional)The Keypad Board provides the input/output interface for the user. It accepts input from the keypad and the various control knobs and sends the appro-priate signals to the DSP on the Digital Board and to the RF Board for proper configuration. It provides the dual display information to inform the user of the status of the radio. It also performs all RS-232 commu-nications between the radio and remote computer stations for the purposes of radio programming, tuning, encryption key loading and software downloading.4.1.2 ANALOG MODEReceive ModeThe signal is routed from the antenna connector to the RF Board where it is filtered, amplified, and mixed with the first local oscillator frequency gener-ated by the synthesizer. The resulting IF signal is also filtered and amplified and sent to the ABACUS chip. The signal is then mixed with the second local oscillator frequency to create a second IF signal of 450 kHz. The second IF signal is then sampled at 14.4 Msps and downconverted to baseband. The baseband signal is then decimated to a lower sample rate that is selectable at 20 kHz. This signal is then routed via a serial interface using a differential current output to the ADSIC chip on the Digital Board. On the Digital Board the ADSIC digitally filters the input signal, performs frequency discrimination to obtain the message signal and then routes the message signal to the DSP. The DSP first performs a carrier- detection squelch function on the radio. If a signal is determined to be present, the audio portion of the signal is resampled to an 8 kHz rate and then filtered appropriately. The filtered signal is then routed back to a D/A in the ADSIC to produce an analog signal for output to the audio power amplifier (PA) and then the speaker. Any detected signaling information is decoded and the resulting information is sent to the microcontroller.
CIRCUIT DESCRIPTION4-2 September 2001Part No. 001-5100-001Transmit ModeThe signal from the microphone is amplified by the audio PA and is then routed to the ADSIC chip where it is first digitized at a 16 ksps rate and then sent to the DSP. The DSP performs the required filtering, adds the desired signaling, converts the sample rate to 48 ksps and then sends the resulting signal back to a D/A in the ADSIC to produce the analog modulation signal for the VCO. The modulated VCO signal is then sent to the RF PA for transmission.4.1.3 PROJECT 25 DIGITAL MODEIntroductionIn Project 25 Digital Mode, the carrier is modu-lated with 4 discrete deviation levels. These levels are ± 600 Hz and ± 1800 Hz. Digitized voice is created using an IMBE™ vocoder.Receive ModeThe signal is processed in the same way as an analog mode transmission until after the squelch func-tion is performed. If a signal is detected to be present, the DSP resamples the signal from 20 kHz to 24 kHz. This is done so that the sample rate is an integer multiple (5x) of the data rate of the digital modulation which is 4800 symbols/sec (9600 bits/sec). The resampled signal is then processed by a demodulator routine to extract the digital information. The resulting bit stream (9600 bps) is sent to a routine that performs unframing, error-correction, and voice decoding. The result of these operations is a recon-structed voice signal sampled at 8 kHz. The sampled voice signal is sent to a D/A in the ADSIC to produce an analog signal for output to the audio power ampli-fier and speaker.Transmit ModeThe microphone signal is processed as in the analog mode until it reaches the DSP. At this point the audio signal is processed by a voice encoding routine to digitize the information. The resulting samples are then converted to a bit stream that is placed into the proper framing structure and error protected. The resulting bit stream has a bit rate of 9600 Hz. This bit stream in then encoded, two bits at a time, into a digital level corresponding to one of the four allowable frequency deviations. This produces 16-bit symbols with a rate of 4800 Hz. The symbols are resampled to a rate of 48 kHz and filtered to comply with channel bandwidth requirements. The filtered signal is then sent to a D/A in the ADSIC to produce the analog modulation signal for the VCO. The modulated VCO signal is then mixed up to the final transmit frequency and then sent to the RF PA for transmission.4.1.4 RF BOARDNOTE: The RF Board is not field serviceable. It must be replaced as a unit with a new board.The receiver front end consists of a preselector, RF amplifier, second preselector, and mixer. Both preselectors on the VHF and UHF board are varactor-tuned, two-pole filters controlled by the microcon-troller unit through the D/A IC. The 800 MHz board uses stripline technology for the preselector. The RF amplifier is a dual-gate gallium-arsenide IC. The mixer is a double-balanced, transformer-coupled active mixer. Injection is provided by the VCO through an injection filter. See Table 4-1 for local oscillator (LO) and first IF information.The frequency generation function is performed by three ICs and associated circuitry. The reference oscillator provides a frequency standard to the synthe-sizer/prescaler IC which controls the VCO IC. The VCO IC actually generates the first LO and transmit injection signals and buffers them to the required power level. The synthesizer/prescaler circuit module incorporates frequency division and comparison circuitry to keep the VCO signals stable. The synthe-sizer/prescaler IC is controlled by the microcontroller through a serial bus. Most of the synthesizer circuitry is enclosed in rigid metal on the RF Board to reduce microphonic effects.

The two pole filters are wide enough to accommodate 5 kHz modulation. Final IF filtering is done digitally in the ADSIC.The ABACUS digital back-end chip consists of an amplifier, second mixer, IF analog-to-digital converter, a baseband down-converter, and a 2.4 MHz synthesis circuit to provide a clock to the ADSIC on the Digital Board. The second LO is generated by discrete components external to the ABACUS. The output of the ABACUS is a digital bit stream that is current driven on a differential pair to reduce noise generation.The transmitter consists of an RF power amplifier IC that amplifies an injection signal from the VCO. Transmit power is controlled by two custom ICs that monitor the output of a directional coupler and adjust the power amplifier control voltages correspondingly. The signal passes through a Rx/Tx switch that uses PIN diodes to automatically provide an appropriate interface to transmit or receive signals. 4.1.5 DIGITAL BOARDThe Digital Board contains the ADSIC, DSP (TMS320C50), static RAM, FLASH memory, and a programmable logic IC. The RF Board and Keypad/Display Board are connected to the Digital Board. The ADSIC performs the Frequency Discrimination and receiver filtering functions. It also performs analog-to-digital (A/D) and digital-to-analog (D/A) conversion. The DSP performs demodulation and modulation, voice encoding and decoding, audio filtering, and squelch signaling. The software for the radio is stored in FLASH memory that is loaded in to static RAM at turn-on. The programmable logic IC controls which device (Flash, SRAM, or UART) is connected to the DSP address and data bus.4.1.6 KEYPAD/DISPLAY BOARDThe Keypad Board contains the microcontroller (HC08), audio circuits, front LCD display assembly, display driver, and 5V analog and 5V digital regula-tors. All interfaces to the side connector and the switches are on this board. The microcontroller deter-mines transmit/receive frequencies, power levels, and display content. It communicates with the DSP via a serial interface.
CIRCUIT DESCRIPTION4-4 September 2001Part No. 001-5100-0014.2 POWER SUPPLY4.2.1 GENERALThe radio is typically powered by a battery which is fastened at the back of the radio. The electrical contact between the battery and the radio occurs on probes located on the Digital board (see Figure 4-1). However the positive battery voltage (UNSWB+) is directly routed through a small flex circuit (Power Flex) to contacts located on the bottom of the RF Board.The UNSWB+ signal is then routed to the RF power amplifier module and ALC IC on the RF Board. It also passes through a fuse and is then routed to the Digital Board.The UNSWB+ signal passes through the Digital Board without being used and is transferred to the Keypad Board. On the keypad board, the UNSWB+ signal is routed as follows:•Input of the 5V digital regulator•Electronic switch which controls the input of the 5V analog regulator and the “switched RF B+”•“On/off switch” located on the top of the radio•Low voltage detector•Audio amplifier power FET4.2.2 POWER ON OPERATIONWhen the user turns the radio on using the top panel “on/off switch”, the following sequence of events occur:1. Power is applied to the shutdown pin of the 5V digital regulator.2. The 5-volt digital supply is created.3. The appearance of the 5V digital supply turns on the electronic switch which applies the battery voltage to the “Switched RF B+” line and to the input of the 5V analog regulator. 4. The 5-volt analog supply is created.5. If the battery voltage is high enough, the low voltage detector output goes high.6. The controller sets the control line to the shutdown pin of the DC/DC converter to a high level.7. The controller sets the radio in an operational mode.4.2.3 POWER OFF OPERATIONWhen the user turns the radio off using the top panel “on/off switch”, the following sequence of events occur:1. The “on/off switch” opens.2. Power is removed from the shutdown pin of the 5V DC/DC converter.3. The controller detects that the power is off through the pin connected to Switched B+.4. The controller performs all required save operations. 5. The controller resets the control line to the shut-down pin of the DC/DC converter.6. The 5-volt Digital source disappears.7. The electronic switch opens.8. The switched RF B+ and 5V analog sources disappear.4.2.4 LOW VOLTAGE DETECTLow battery voltage is detected by a comparator chip. When a low voltage condition is detected (less than 6.3V), the following actions occur:1. The low voltage detector output goes low which alerts the controller.2. The controller prevents any action which could have a damaging effect (like writing in flash memory).3. The controller releases its control of the shutdown pin of the DC/DC converter.4. The transmitter switches to the low power mode.

The 5-volt analog and switched RF B+ sources turn off.4.3 RF BOARD CIRCUIT DESCRIPTION4.3.1 FREQUENCY GENERATION UNITThe Frequency Generation Unit (FGU) consists of these three major sections: (1) high stability refer-ence oscillator, (2) fractional-N synthesizer, and (3) VCO buffer. A 5-volt regulator supplies power to the FGU. The regulator output voltage is filtered and then distributed to the transmit and receive VCOs and the VCO buffer IC. The mixer LO injection signal and transmit frequency are generated by the receive VCO and transmit VCO, respectively. The receive VCO uses an external active device, and the transmit VCO active device is a transistor inside the VCO buffer. The receive VCO is a Colpitts-type oscillator. The receive VCO signal is received by the VCO buffer where it is amplified by a buffer inside the IC. The amplified signal is routed through a low-pass filter and injected as the first LO signal into the mixer. In the VCO buffer, the receive VCO signal is also routed to an internal prescaler buffer. The buffered output is applied to a low-pass filter. After filtering, the signal is routed to a prescaler divider in the synthesizer.The divide ratios for the prescaler circuits are determined from information stored in an EEPROM. The microprocessor extracts data for the division ratio as determined by the position of the channel-select switch and routes the signal to a comparator in the synthesizer. A 16.8 MHz reference oscillator applies the 16.8 MHz signal to the synthesizer. The oscillator signal is divided into one of three pre-determined frequencies. A time-based algorithm is used to generate the fractional-N ratio.If the two frequencies in the synthesizer’s comparator differ, an error voltage is produced. The phase detector error voltage is applied to the loop filter. The filtered voltage alters the VCO frequency until the correct frequency is synthesized.In the transmit mode, the modulation of the carrier is achieved by using a two-port modulation technique. The modulation for low frequency tones, such as CTCSS and DCS, is achieved by injecting the tones into the A/D section of the fractional-N divider, generating the required deviation. Modulation of the high frequency audio signals is achieved by modu-lating the varactor through a frequency compensation network.RF BOARD
CIRCUIT DESCRIPTION4-6 September 2001Part No. 001-5100-001The transmit VCO signal is amplified by an inter-nal buffer, routed through a low-pass filter, and then sent to the transmit power amplifier module. The refer-ence oscillator supplies a 16.8 MHz clock to the synthe-sizer where it is divided down to a 2.1 MHz clock. This divided down clock is fed to the ABACUS IC.4.3.2 ANTENNA SWITCHA pair of diodes is used to electronically steer the RF signal between the receiver and transmitter. In the transmit mode, RF is routed through a transmit switch-ing diode and sent to the antenna. In receive mode, RF is received from the antenna, routed through a receive switching diode and applied to the RF amplifier.4.3.3 RECEIVER FRONT ENDThe RF signal from the antenna is sent through a bandpass filter. The bandpass filter is electronically tuned by the microcontroller via the D/A IC by applying a control voltage to the varactor diodes in the filter. The D/A output range is extended through the use of a current mirror. Wideband operation of the filter is achieved by retuning the bandpass filter across the band.The output of the bandpass filter is applied to a wideband amplifier. After being amplified by the RF amplifier, the RF signal is further filtered by a second broadband, fixed tuned, bandpass filter to improve spurious rejection.The filtered RF signal is routed via a broadband 50 Ω transformer to the input of a broadband mixer/buffer. The mixer uses GaAs FETs in a double-balanced Gilbert Cell configuration. The RF signal is mixed with a first LO signal of about –10 dBm supplied by the FGU. Mixing of the RF and the first LO results in an output signal which is the first IF frequency according to Figure 4-1. The first IF signal output is routed through a transformer and impedance matching components and is then applied to a two- pole crystal filter. The 2-pole crystal filter removes unwanted mixer products.4.3.4 RECEIVER BACK ENDThe output of the crystal filter is matched to the input of the IF buffer amplifier transistor. The output of the IF amplifier is applied to a second crystal filter through a matching circuit. This filter supplies further attenuation at the IF sidebands to increase radio selectivity. In the ABACUS IC the first IF frequency is amplified and then downconverted to 450 KHz, the second IF frequency. At this point, the analog signal is converted into two digital bit streams via a sigma-delta A/D converter. The bit streams are then digitally filtered and mixed down to baseband and filtered again. The differential output data stream is then sent to the ADSIC on the Digital Board where it is processed to produce the recovered audio.The ABACUS IC is electronically program-mable, and the amount of filtering, which is dependent on the radio channel spacing and signal type, is controlled by the microcontroller. Additional filtering, which used to be provided externally by a conven-tional ceramic filter, is replaced by internal digital filters in the ABACUS IC. The ABACUS IC contains a feedback AGC circuit to expand the dynamic range of the sigma-delta converter. The differential output data contains the quadrature (I and Q) information in 16-bit words, the AGC information in a 9-bit word, imbedded word sync information and fill bits depen-dent on sampling speed. A fractional-N synthesizer is also incorporated on the ABACUS IC for 2nd LO generation.The 2nd LO/VCO is a Colpitts oscillator. The VCO has a varactor diode to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter.4.3.5 TRANSMITTERThe transmitter consists of three major sections: Harmonic Filter, RF Power Amplifier, and the ALC (Automatic Level Control) circuit.The RF signal from the PA module is routed through a coupler, then through the harmonic filter, then to the antenna switch. The RF power amplifier module is a wide-band multi-stage amplifier. The nominal input and output impedance of the power amplifier is 50 Ω. The DC bias for the RF power amplifier is controlled by a switching transistor. The microcontroller uses the D/A IC to produce a ready RF BOARD (CONT’D)
CIRCUIT DESCRIPTION4-7 September 2001Part No. 001-5100-001signal for the transmit ALC IC. The synthesizer sends a LOC signal to the transmit ALC IC. When both the ready signal and LOC signal are available to the transmit ALC IC, the switching transistor for the RF power amplifier is turned on.A coupler module samples the forward power and the reverse power of the PA output voltage. Reverse power is present when there is other than 50 Ω imped-ance at the antenna port. Sampling is achieved by coupling some of the forward and/or reverse power for rectification and summing. The resulting DC voltage is then applied to the transmit ALC IC as an RF strength indicator.The transmit ALC circuit is the core of the power control loop. Circuits in the transmit ALC module compare the RF strength indicator to a reference value and generate a bias signal that is applied to the base of a transistor. This transistor varies the DC control voltage applied to the RF PA controlling the RF power.4.4 DIGITAL BOARD4.4.1 INTRODUCTIONThe Digital Signal Processing (DSP) functions are performed by the DSP chip (U12) and the ADSIC (U3) with the support of FLASH (U2) and SRAM (U5, U6) memory devices. Functions previously performed in hardware like filtering and limiting are performed by software running in the DSP chip. The digital board connects with the Keypad Board via J4 and with the RF board via J1.4.4.2 DIGITAL SIGNAL PROCESSING OVERVIEWThe DSP section consists of a DSP chip (U12), the ADSIC (U3), two 128K x 8-bit Static RAM chips (U5, U6), one 512K x 16-bit FLASH ROM memory chip (U2), a UART chip (U7), a programmable logic IC (U1), and two glue-logic chips (U4, U9). The FLASH ROM contains the program code executed by the DSP. Depending on the operational mode selected for the radio, different sections of the program code in the FLASH ROM are copied into SRAM for faster execution.The ADSIC is a support chip for the DSP. It provides the interface between the DSP and the analog signal paths, and between the DSP and the ABACUS chip on the RF Board. Configuration of the ADSIC is handled primarily by the microcontroller. The DSP has access to a few memory-mapped registers on the ADSIC.In receive mode, the ADSIC interfaces the DSP with the ABACUS IC on the RF Board. The ADSIC collects the I and Q samples from the ABACUS and performs channel filtering and frequency discrimina-tion on the signals. The resulting demodulated signal is routed to the DSP via the serial port for further processing. After the DSP processing, the signal is sent to the ADSIC Speaker D/A by writing to a memory- mapped register. The ADSIC then converts the processed signal from the DSP to an analog signal and then outputs this signal to the speaker power amplifier on the keypad board. In transmit mode the ADSIC Microphone A/D digitizes the analog signal from the microphone. The DSP reads these values from a memory-mapped register in the ADSIC. After processing, the DSP sends the modulation signal to the ADSIC via the serial port. In the ADSIC, the VCO D/A converts the sampled modulation signal into an analog signal and then routes this signal to the VCO on the RF Board.4.4.3 RECEIVE SIGNAL PATHThe ABACUS IC on the RF Board provides a digital back end for the receiver section. It provides a digital output of I (in phase) and Q (quadrature) samples which represent the IF signal at the receiver back end. These samples are routed to the ADSIC where the signal is filtered and frequency discrimi-nated to recover the modulating signal. The recovered signal is sent to the DSP chip for processing. The ADSIC interface to the ABACUS is comprised of four signals SBI, DIN, DIN*, and ODC. The ODC signal is a clock the ABACUS provides to the ADSIC. Most internal ADSIC functions are clocked by this ODC signal at a rate of 2.4 MHz and are available as soon as the power is supplied to the circuitry. This signal initially may be 2.4 or 4.8 MHz after power-up. It is programmed by the ADSIC through the SBI signal to 2.4 MHz when the ADSIC is REVISION 2 DIGITAL BOARD
CIRCUIT DESCRIPTION4-8 September 2001Part No. 001-5100-001initialized by the microcontroller through the SPI bus. For any functionality of the ADSIC to exist, including initial programming, the reference clock must be present. SBI is a programming data line for the ABACUS. This line is used to configure the operation of the ABACUS and is driven by the ADSIC. The microcon-troller programs many of the ADSIC operational features through the SPI interface. There are 36 configuration registers in the ADSIC of which 4 contain configuration data for the ABACUS. When these particular registers are programmed by the microcontroller, the ADSIC in turn sends this data to the ABACUS through the SBI.DIN and DIN* are the data lines in which the I and Q data words are transferred from the ABACUS. These signals make up a differentially encoded current loop. Instead of sending TTL-type voltage signals, the data is transferred by flowing current one way or the other through the loop. This helps reduce internally generated spurious emissions on the RF Board. The ADSIC contains an internal current loop decoder which translates these signals back to TTL logic and stores the data in internal registers.The ADSIC performs digital IF filtering and frequency discrimination on the signal, sending the baseband demodulated signal to the DSP. The internal digital IF filter is programmable with up to 24 taps. These taps are programmed by the microcontroller through the SPI interface.The DSP processes this data through the SSI serial port. This is a six-port synchronous serial bus. The ADSIC transfers the data to the DSP on the TxD line at a rate of 2.4 MHz. This is clocked synchro-nously by the ADSIC which provides a 2.4 MHz clock on SCKT. In addition, a 20 kHz interrupt is provided on TFS to signal the arrival of a data packet. This means a new I and Q sample data packet is available to the DSP at a 20 kHz rate which represents the sampling rate of the received data. The DSP then processes this data to extract audio, signaling, and other information based on the 20 kHz interrupt.In addition to the SPI programming bus, the ADSIC also contains a parallel configuration bus. This bus is used to access registers mapped into the DSP memory. Some of these registers are used for addi-tional ADSIC configuration controlled directly by the DSP. Some of the registers are data registers for the speaker D/A. Analog speaker audio is processed through this parallel bus where the DSP outputs the speaker audio digital data words to this speaker D/A. In addition, an analog waveform is generated which is output to SDO (Speaker Data Out). In conjunction with speaker D/A, ADSIC contains a programmable attenuator to set the rough signal attenuation. However, the fine levels and differ-ences between signal types are adjusted through the DSP software algorithms. The speaker D/A attenuator setting is programmed by the microcontroller through the SPI bus.The ADSIC provides an 8 kHz interrupt to the DSP on IRQB for processing the speaker data samples. This 8 kHz signal must be enabled through the SPI programming bus by the microcontroller and is necessary for any audio processing to occur.4.4.4 TRANSMIT SIGNAL PATHThe ADSIC contains an analog-to-digital (ADC) converter for the microphone. The microphone path in the ADSIC also includes an attenuator that is programmed by the microcontroller through the SPI bus. The microphone input in the ADSIC is on pin MAI (U3-19). The microphone ADC converts the analog signal to a series of data words and stores them in internal registers. The DSP accesses this data through the parallel data bus. As with the speaker data samples, the DSP reads the microphone samples from registers mapped into its memory space. The ADSIC provides an 8 kHz interrupt to the DSP on IRQB for processing the microphone data samples.The DSP processes these microphone samples and generates and mixes the appropriate signaling and filters the resultant data. This data is then transferred to the ADSIC on the DSP SSI port. The ADSIC gener-ates a 48 kHz interrupt so that a new sample data packet is transferred at a 48 kHz rate and sets the transmit data sampling rate at 48 ksps. These samples are then input to a transmit D/A which converts the data to an analog waveform. This waveform is the modulation signal from the ADSIC and is connected to the VCO on the RF Board.DIGITAL BOARD (CONT’D)
CIRCUIT DESCRIPTION4-9 September 2001Part No. 001-5100-0014.4.5 DSP CHIP (U12)DSP chip U12 has a 16-bit data bus and a 16-bit address bus. It has 10K words of internal SRAM from which 0.5K are used only to store data and 9.5K are used either for data or for program storage. The DSP bus can access through its buses the following external devices:SRAM U5 and U6 - These two chips are 128K x 8 chips. U5 stores the lower byte of the word while U6 stores the higher byte. Those chips are selected by asserting CE2 high and CE1* low. The programmable logic IC is responsible for controlling the select lines of these ICs.FLASH ROM U2 - This chip is 512K x 16 words in size. It is selected by asserting CE* low. The program-mable logic IC is responsible for controlling the select line of this IC.ADSIC U3 - The ADSIC contains several registers which can be read from or written to by the DSP. The ADSIC IC has an output which drives a data/address bus enable signal for the programmable logic IC.UART U7 - This chip converts data from the DSP into serial data. It is used to interface with the optional encryption board.Programmable Logic U1 - This IC arbitrates access to the DSP’s address/data bus between the flash (U2), SRAMs (U5,U6), and UART (U7). The DSP can modify the memory configuration by writing to a series of registers in the programmable logic IC. In order to reduce power consumption, the programmable logic IC can be “disconnected” from the DSP’s address/data bus using the bus enable input on the programmable logic IC (pin 44).The DSP uses memory as data space, program space, and I/O space as follows. Refer to Figure 4-3 for more information.Program Space - Internal SRAM, external SRAM, and FLASH memory.Data Space - Internal SRAM and external SRAM.I/O Space - Programmable logic IC, ADSIC, and the UART. The DSP accesses the difference spaces by setting the corresponding lines PS*, DS*, IS* low. Only one of these three signals can be low at a given time. When the DSP accesses internal SRAM, none of these lines is activated.The programmable logic IC (PLD) acts as the primary arbitrator of the DSP’s memory map. The FLASH ROM and the SRAM are both mapped in the program space and cannot both be active at the same time. The DSP may control which type of memory is mapped in program space by enabling the program-mable logic IC (PLD), then manipulating a register in the PLD. In addition, the DSP can manipulate other registers to control paging of both the Flash and the SRAM. Paging refers to the swapping of 64K word blocks of Flash or SRAM into or out of the DSP’s memory map.FLASH ROM U2 is used to permanently store the program to be executed in the DSP. However, it is slow to access, so to fully utilize the speed of the DSP, the program stored in the FLASH ROM must be copied into the SRAM. As the size of the SRAM is half the size of the FLASH ROM, only the code required for the current mode of operation is copied in the SRAM. As previously mentioned, the FLASH ROM and the SRAM cannot be active at the same time. Thus we use the internal data memory as a temporary buffer to transfer the program from the FLASH ROM to the SRAM.The following hardware interrupts are used on the DSP:Connector J2 allows connection to an emulator for debugging purposes. The emulator connects to some dedicated pins on the DSP.Interrupt DescriptionINT1* 8 kHz interrupt for speaker DAC and micro-phone ADC from ADSICINT2* 125 kHz signal from ADSICINT3* 2 kHz timer interrupt from the Controller on the Keypad Board.INT4* Interrupt from the UARTNMI* Not usedDIGITAL BOARD (CONT’D)
