Introduction Version 0.5 AMIMON Confidential 8 Chapter 1 Introduction The AMN12310 is the second generation of WHDITM receiver board. It is based on AMIMON's WHDI receiver chipset: the AMN2210 baseband receiver and the AMN3210 RFIC receiver. The AMN12310 WHDITM wireless receiver module, together with the AMN11310 wireless transmitter module, presents the ultimate solution for converting any High Definition (HD) system into a wireless one. These add-on modules enable wireless A/V applications that easily fit into the living room and eliminate traditional A/V wiring. The perfect HD video and audio quality and the high robustness are unmatched by any other wireless technology, and present a true alternative to cable. The WHDI system transmits uncompressed video and audio streams wirelessly and thus simplifies and eliminates system issues, such as: lip-sync, large buffers and other burdens like retransmissions or error propagation. 1.1 Features • Uncompressed and uncompromised HD video quality, using AMIMON's baseband chipsets:  AMN2210: WHDITM Baseband Receiver  AMN3210: WHDITM RFIC Receiver • WHDI – Wireless High Definition Interface:  Digital video: 30-bit RGB or YCrCb  Digital audio: I2S and SPDIF  Two-wire serial bus slave interface  One interrupt line • Supports any uncompressed video resolutions, including:  HD: 720p, 1080i, 1080p, 576i, 576p, 480p, 480i  PC: VGA (640x480), SVGA (800x600), XGA (1024x768)  Panel: 854x800, 1280x768, 1366x768 • Audio:  Up to 3Mbps audio stream:  I2S: Two PCM channels (sampled up to 48 KHz x 24 bit)  SPDIF: Including AC-3, DTS • Strong 256-bit AES encryption • User-defined two-way channel with minimum 10 Kbps for data and control • Less than 1mSec latency between source and sink

Overview Version 0.5 AMIMON Confidential 11 Chapter 2 Overview The AMN12310 WHDI Video Display Unit (VDU) is designed to be at the receiver end of the WHDI downstream. The AMN12310 receives wireless downstream transmission, demodulates it and regenerates the video, audio and control content transmitted by the AMN11310 WHDI transmitter. The receiver works at the 5GHz unlicensed band. Figure 1 displays a block diagram of the AMN12310. It has an MIMO design of five wireless input channels, and one slow rate output wireless channel, which generates an upstream channel for data content transmissions. The outputs from the VDU are digital uncompressed video, digital audio and control, all via the WHDI connector. The MAC uC is responsible for the control and the management. 80 Pin WHDITHConnectorSPIVIDEOControlTwoWireRESETInterruptAudioIntAMN2210WHDITM Baseband ReceiverCLKOutCLKInControlTwo-Wire40M XTALAMN3210uCMACCY22150VideoPLLPArssiclken3.3VRX_ANT0_P/NClk40M_OECLK40M DIG_CLK (40M)3.3V_RAIL3.3VS_RESET_BUC_MAC_CLK(Clo ck 10MHz)PIN#15PIN 5#PIN#6 1PIN #37 -40PIN #62fb Figure 1: AMN12310 Block Diagram

Five analog-to-digital converters and one digital-to-analog converter are embedded within the chip. The AMN2210 internal PLL accepts an input clock frequency of 40MHz. The input frequency is multiplied and then used as an internal system clock. 2.2 STM32F MAC µController The STM32F Microcontroller is based on an ARM 32-bit Cortex™-M3 CPU, with 128 Kbytes of embedded Flash memory. It is used as an external microcontroller for implementing the MAC layer of the WHDI link. The STM32F Internal PLL accepts an input clock frequency of 10MHz and generates an internal 60MHz system clock. The STM32F also has the option to work with an internal 4-to-16 MHz crystal oscillator.

Overview Version 0.5 AMIMON Confidential 13 2.3 AMN3210 WHDITM 5GHz Transceiver The VDU uses AMN3210 WHDI receiver chip. The AMN3210 is a fully integrated Zero-IF MIMO receiver specifically designed for WHDI applications using OFDM modulation for single-band 4.9GHz to 5.9GHz. The device includes: • Five Complete Downlink Zero-IF Receivers • One Uplink Direct Conversion Transmitter • Integrated Synthesizer/VCO • Internal DC Servo Loops • RSSI, RF and Baseband Control Interface • Power Management Unit • 3-Wire SPI Interface To complete RF front-end solution, the AMN3210 uses external PA, RF Band Pass Filters (BPF), RF BALUNs and a few passive components. 2.4 Power Amplifier (PA) In order to extend the operating range for the AMN12310 upstream, the RF transmitter uses a power amplifier. The power amplifier has an output power detector for TPC purposes. AMN12310 uses Sharp IRM053U7 PA. 2.5 Board Connector (WHDITM Connector) For information regarding the connector specification and pin-outs see section 4.1, Signals, page 26. 2.6 Clocks 2.6.1 40MHz Crystal Oscillator An on-board 40MHz crystal oscillator is connected to the AMN3210 chip. 2.6.2 40Mhz Digital Clock AMN3210 drives the 40MHz clock to the baseband AMN2210 through a buffer (with output enable). This clock is named DIG_CLK. The control to the output buffer is named Clk40M_OE. 2.6.3 10Mhz Micro Controller Clock The DIG_CLK (40MHz) clock is divided by four by the AMN2210 and generates 10MHz that drives the STM32F UC.

Overview Version 0.5 AMIMON Confidential 14 2.7 CY22150 External Video PLL An external PLL is used for re-generating the video clock. The PLL receives a lower speed clock (generally limited to 10 MHz), which is generated inside the AMN2210 according to the video parameters. The PLL multiplies the clock to the desired speed dictated by the incoming video format (for example: 74.25Mhz for 720p or 1080i).

Interfaces Version 0.5 AMIMON Confidential 15 Chapter 3 Interfaces 3.1 Video Data Input and Conversions Figure 3: Video Data Receiver Path Figure 3 shows the basic control over the video data output. Essentially the receiver mirrors the video format of the transmitter end and so most of the configurations are done on the transmitter end. The video output data is uncompressed digital video up to 3*10 bits in width. The video interface provides a direct connection to the inputs of a display device, an HDMI transmitter, or any other video interface device. Color Space Converter The receiver can output either RGB or YCbCr color space. For more details, you may refer to the MAC registers in the programmer's reference guide. Color Range Limiter The YCbCr data range can be limited to 16-235.

The first option is the default from power-up. In order to change the video channel mapping, refer to the appropriate programmer's reference guide. 3.2 Video Interface Output Timing Diagram 3.2.1 Timing Requirements Important: The following parameters relate to the AMN2210 baseband chipset and not to the entire AMN12310 board.

Interfaces Version 0.5 AMIMON Confidential 17 3.2.1.1 Timing Diagram EDGE = 0 EDGE = 1 Figure 4: Timing Diagram 3.3 Audio Data Capture AMN12310 audio processing logic block receives the audio stream from the WHDI wireless link and regenerates the appropriate clock and data. If the transmitter end was configured to SPDIF audio interface, then the audio is output on the receiver side through the SPDIF. The same is true for the I2S interface. No constraints exist for a coherent video and audio clock, where coherent means that the audio and the video clock must have been created from the same clock source. The AMN12310 supports two-channel audio-sampling frequencies of up to 48 KHz, 32 bits per sample.

Interfaces Version 0.5 AMIMON Confidential 18 3.3.1 I2S Bus Specification The AMN12310 supports a standardized communication structure inter-IC sound (I2S) bus. As shown in Figure 5, the bus has three lines: continuous serial clock (SCK), word select (WS) and serial data (SD). In addition, it has a MCLK signal which is synchronized to and a multiple of the WS. The external device generating SCK and WS is the AMN12310. Figure 5: I2S Simple System Configurations and Basic Interface Timing The AMN12310 outputs exactly 32 bits for each channel (left and right). By default, the serial data is valid on the leading (LOW to HIGH) edge of the clock signal, but it can also be configured to be valid on the edge (HIGH to LOW) of the clock signal. The WS is also valid by default on the leading edge of the clock signal. The WS line changes one clock period before the first bit of the transmitted channel. The AMN12310 mirrors the transmitter's end audio inputs and so the MSB and the LSB position are defined at the audio source at the transmitter side. In case the audio samples in the transmitter are less than 32 bits long, they are padded with zeroes to generate receiver output samples of 32 bits. 3.3.1.1 MUTE The AMN12310 has an error detection mechanism. It outputs a high MUTE signal in case of bad audio reception (bad frames).

The default configuration of the MCLK frequency is 256 times the sampling frequency of the audio signal. For example, if the audio sampling frequency is 48 KHz, the MCLK frequency will be 12.288 MHz. The following table provides the specification of the MCLK –

Interfaces Version 0.5 AMIMON Confidential 21 3.4 Management Buses and Connectors 3.4.1 Two-Wire Serial Bus Interface The WHDI application observes and controls the AMN12310 via a Two-Wire interface and an interrupt line connecting the application microcontroller and the AMN12310 MAC microcontroller. The protocol of the Two-Wire-bus for the WHDI application / MAC interface is described in the following sections. The Two-Wire bus is bidirectional and, as its name implies, it has only two wires: a Serial Clock Line (SCL) and a Serial Data Line (SDA). The Two-Wire architecture includes master and slave devices. The master initiates a data transfer on the bus and generates the clock signal. The AMN12310 MAC operates as a slave device. Each slave device is recognized by a unique address and can operate as either a receive-only device or a transmitter with the ability to both receive and send information. Application MicroController(Two-Wire Master)WHDI MAC(Two-Wire Slave)SDASCL Figure 7: Two-Wire/Application-MAC Connection On top of the Two-Wire low level operation described in sections 3.4.1.3 and 3.4.1.4, the WHDI Application and the MAC microcontrollers communicate with each other in a defined protocol, which avoids all possibilities of confusion. The protocol defines command oriented transactions between the application and the WHDI MAC. Each Two-Wire command has a predefined data byte length and is defined to be exactly one Two-Wire transaction long. 3.4.1.1 Two-Wire Timing Generally, the clock frequency of the bus is dictated by the slowest device on the Two-Wire interface. However, the selected MAC supports the 100 KHz SCL frequency rate. Refer to STM32F Two-wire reference application note for detailed description of the physical protocol and timing. http://www.st.com/stonline/products/literature/ds/13587.pdf, pp 55-59. 3.4.1.2 Device Addresses The MAC device address may be altered by two jumpers on VDU/VSU board. Table 7: Device Addresses Device Address MAC uC 0x62 or 0x82 or 0x90 or 0x70 (Board configuration dependant) Alternatively, the device address can be set in the MAC SW in advance.

Interfaces Version 0.5 AMIMON Confidential 22 3.4.1.3 MAC uC Write Operation Figure 8 demonstrates a write transaction which sends 2 data bytes and which ends with the master stop bit. Each write transaction sends one or more data bytes to the MAC, beginning at an explicit 2 bytes long address. Multiple data bytes may be written as the MAC stores the received register data until the master sends a stop bit. The MAC updates the register value upon a successful termination of a write transaction.

The read transaction is divided into two parts. In the first part, the Two-Wire master sends a write command to the slave containing only the required start address. (The address is always 2 bytes long.) In the second part, multiple bytes may be read from consecutive addresses. The MAC puts the appropriate data on the Two-Wire bus and the internal address is automatically incremented. A stop bit is sent by the master only when the entire transaction has been completed.

Each register has an associated group id and index offset address. The group id and the index offset are each 1 byte long. Together they define a register address that is 2 bytes long. Each register has an attributed length (in byte units). All registers within the same group have the same length. A Two-Wire transaction to a specific register includes 2 bytes of register address and the register data bytes. The register is written in one transaction. If the transaction terminates ahead of time or is too long, the MAC issues an error interrupt and does not store the received values. The register is read in one transaction, as described in section 3.4.1.4. If the read transaction finishes ahead of time, the MAC issues an error interrupt. 3.4.2 Interrupts There is one interrupt connected to the WHDI connector. The interrupt source is the AMN2210 MAC uC. For details about the interrupt, please refer to the programmer's user guide. . The interrupt active polarity is set in SW or by configuration resistors on board – see 3.4.3.

Assertion of the STM32F reset switches the clock of uC to the internal oscillator until the Albatross does not assert an INIT_DONE interrupt. Assertion of the Albatross reset enables the generation of the 10 MHz clock. After a hard reset, the MAC asserts the SW reset signal which just clears the registers without resetting the clock generation scheme. When the INIT_DONE is asserted, it indicates the completion of the Albatross initialization and that the 10 MHz clock is stable. At that point, the uC switches to the external clock source from the Albatross and enable communication with the application microcontroller. clkrstT−STrstTinitT Figure 10: Reset Time Diagram

Design Guidelines Version 0.5 AMIMON Confidential 33 6.1.2 General Guidelines • Keep traces as short as possible. • Traces should be routed over full solid reference plans. • Sensitive lines like reset and clocks should be routed with special care.  These lines should be routed over full solid power plans (ground or power).  Traces should be routed at least two times the trace width away from other lines in the same routing layer.  Place a series resistor ~30 ohm at the clock source. • Keep digital signals away from the analog side. 6.1.3 WHDI Lines • Place series resistors on all output lines (near the outputs pins). • Series resistors on input lines are unnecessary. (The series resistors should be placed on the interface board.) 6.1.4 Power and Ground • Use a solid ground plan. • Ground plans separation is unnecessary. • Place decoupling capacitors near power pins. (Refer to the schematics and BOM for recommended values.) • Analog power pins should be filtered with ferrite beads. (Refer to the schematics and BOM for recommended values.) • Add as many ground vias as possible, for better ground connections between layers and better heat dissipation. 6.2 RF Design Recommendation 6.2.1 RF Components All passive components must have compatible performance with components used in the Amimon reference design. 6.2.2 Power Management The RF power rail 3.3V_RAIL is separated from the digital power rail 3.3 with ferrite bead.
