2. Overview

2.1 Application Descriptions

The CDMA Wireless Data Module is a complex consumer communications instrument that relies

heavily on both digital signal and embedded processor technologies. The Wireless Data Modules

manufactured by AnyDATA.NET support Code-Division Multiple Access (CDMA). This operates in

both the cellular and PCS spectrum band.

In a continuing effort to simplify the design and to reduce the size and production cost of the

Wireless Data Module, AnyDATA.NET has successfully developed the DTG series. The DTG2000-Dual

is AnyDATA.NET’s latest compact Wireless Data Module operating in the Cellular and PCS spectrum

band. The DTG2000-Dual contains not only a complete digital modulation and demodulation system for

CDMA standards as specified in IS-95 A/B and IS-2000, but also GPSOne position location solution

which offers wireless callers their location wherever and whenever they need it.

GPSOne is QUALCOMM CDMA Technologies’ position location solution. It offers the availability

of position location determination in hostile environments (such as indoors) where conventional

GPS receivers do not work well.

GPSOne uses a hybrid approach that utilizes signals from the GPS satellite constellation and from

CDMA cell sites to determine location. Using the hybrid approach, GPSOne enhances location

services availability, accelerates the location determination process, and provides improved

accuracy.

The hybrid mode approach for position location uses signals from CDMA cell stations and GPS

satellites to compute the user’s location. This approach basically takes advantage of an accurate

knowledge of GPS system timing on a CDMA mobile station. The knowledge of system timing

allows the GPSOne solution to use both the CDMA signal measurements and GPS signal

measurements collectively to compute the user’s location. It also allows for a central entity, named

Position Determination Entity (PDE), to send estimated signal phases to the mobile. This knowledge

reduces the time to search the satellite pseudo ranges on the mobile, thus improving the time taken to

determine the user’s position.

The subsystem in the DTG2000-Dual includes a CDMA processor (MSM6050), an integrated

CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward

link data communications at a rate of 153kbps.

The DTG2000-Dual provides an external interface that includes the standard RS-232, Digital Audio,

External reset control, parallel LCD Display, Keypad, Ringer extension ports and R-UIM for China

The DTG2000-Dual has the capability to power down unused circuits in order to dynamically

minimize power consumption.

4. Interface Descriptions

4.1 Overview

This chapter covers information required to convert the DTG2000-Dual into a subscriber unit

application. In addition, some of the internal blocks of the device are described. Understanding these

internal blocks is necessary for one to completely grasp the functions of the various interfaces.

This chapter discusses the interface to the major blocks of the DTGD2000-Dual as shown in the

following figure. These blocks include:

 Power Up

 CODEC Interface

 UART Interface

 General Purpose Interface

 External Hardware Reset

 User Interface

4.2 Powering Up the Module

There are two ways to power up the module and customers may choose one of the two ways to power

up DTG2000.

4.2.1 Supply input to +VEXT_DC (Pin 87 and Pin 89)

If the customers don’t need to save current in sleep mode, which is around 15mA, supplying the

voltage input to +VEXT_DC (Pin 87 and 89) is recommended.

When the input voltage from +4V to +5.0V is supplied, DTG2000 will automatically start its power-on

process and finish it within 2 seconds. In this case, using a regulator with an enable pin is highly

recommended so that the customer can reset the module using the enable pin if software lock-up

symptoms are found.

If a customer needs to use charging circuit built in the module, apply +4.5V DC to +VEXT_DC (Pin87

and 89) and connect the 3.6V 1cell lithium-ion battery to BATT_INT (Pin86 and 88).

AnyDATA.NET Inc. AnyTime AnyPlace Any Wireless Data SolutionTM

-20-

4.2.2 Supply Input to BATT_INT (Pin 86 and Pin 88)

If the customers need to get their device to operate in a very low sleep current mode, supplying the

voltage input to BATT_INT (Pin 86 and 88) is recommended.

When the input voltage from +3.4V to +4.3V is supplied to BATT_INT(Pin86 and 88), DTG2000

won’t automatically start its power-on process without low assertion of POWER_ON (Pin 67). To power

the module on, first apply VCC to BATT_INT and have POWER_ON (Pin 67) stay low for more than

500 msec and less than 2 sec.

POWER_ON (Pin 67) needs to be externally pulled up to 3V to 3.6V thru 100kohm resistor.

To power off the module, have POWER_ON(Pin 67) stay low for more than 2sec and less than 4sec and

then the voltage in BATT_INT may or may not be removed.

If Vcc is supplied thru a regulator to BATT_INT(Pin86 and 88), using a regulator with an enable pin is

highly recommended so that the customer can shut off the power to the module using the enable pin if

software lock-up symptoms are found. If the modem is locked up, low assertion of POWER_ON(Pin 67)

won’t power on or off the module.

If Vcc is supplied directly from a battery, having a FET between the output of a battery and input of

DTG2000 is recommended that the customer can shut off the Vcc to DTG2000 using the FET.

4.3 CODEC Interface

With the integrated microphone and earpiece amplifier including CODEC, the DTG2000-Dual

module interfaces directly, either differential or single-ended, to the microphone and earpiece.

The audio features in the module are

- Two microphone inputs

- Two earphone outputs and one auxiliary audio output.

4.3.1 Internal CODEC Interface

The module contains analog audio interface circuitry. The contained audio interface supports all of the

required conversation and amplification stages for the audio front end.

The audio interface includes the amplification stages for both the microphone and earphone.

The EAR10 and MIC1P are typically used for the handset microphone,

The EAR_JACK+ and MIC2P are typically used for the ear-jack.

Note:

* MIC2, along with being a microphone input, checks to see if the user has pressed the headset key,

which allows the user to connect to or disconnect from a call. This pin is internally pulled high and is

therefore normally in the high state. To activate this input and connect to or disconnect from a call, the

user must set the MIC2 pin to a low state for 100ms to 200ms.

** EAR_DET1 checks to see if a headset has been connected to the ear-jack. When there is no headset

connected to the ear-jack, the audio path thru an ear jack is disconnected. When a headset is connected to

the ear-jack, audio path is opened. To simulate a headset connected to the ear-jack, the user must apply a

low signal to the EAR_DET1 pin for as long as the user wants the audio path to be kept open.

4.3.2 Extended CODEC Interface

The PCM CODEC interface is used for the car-kit audio system. This interface is optional.

4.4 UART Interface

The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that

conforms to the RS-232 Interface protocol. The module has 3 UARTs which provides 3.0V CMOS level

outputs and 3.0V CMOS input levels. All the control signals of the RS-232 are active low, however the

data signals, RXD and TXD, are active high.

UART1 which has 512 bytes for Tx and Rx FIFO, supports high speed data communication up to

230.4kbps, program download and diagnostic monitor function.

UART2 and 3 which 64 bytes for T/Rx FIFO, support low speed data communication up to 115.2kbps,

program download and diagnostic monitor function.

4.6 External Hardware Reset and Power Down Registration

4.6.1 External Hardware Reset (Pin #31)

There are two types of resets that the user can employ to restart the module. The first type will reset

the MSM and the memory and is performed when the user gives the AT command, AT+RESET, to the

MSM. Another way to reset the module is by using the external hardware reset. This type of reset will

reset the hardware as well as the MSM and the memory. The flash memory will be the only information

that is kept. To perform an external hardware reset, make sure the module has powered on and is not in

the initialization stage, and then pull low the external hardware reset pin (Pin #31) for 200ms to 500ms.

Keep the external hardware reset pin high or floating when the module is initializing and booting up as

well as during normal operation. This pin is internally pulled up to +3.0V.

4.6.2 Power Down Registration

Before DTG-2000 is powered off, it has to send power down registration message to the CDMA

base station to help the base station to maximize its capacity. Depending on air interface environment, it

may take 12 seconds at maximum according to CDMA technical standard.

4.7 User Interface

4.7.1 Keypad

The keypad interface consists of a 5 X 6 matrix pattern. The 5-KEYSENSE/[4:0] pins are used to

connect a matrix keypad to the module. The KEYSENSE/ pins are active low.

The 6-KEYPAD pins are necessary to construct the other side of the matrix. These KEYPAD pins

must be active high in order for the keypad matrix to work properly. The general keypad matrix is shown

below:

Figure 4-1 Keypad Matrix

DTMF

When key is pressed, CDMA Module generates standard DTMF tone and sends it to the local

audio path (speaker). If the Mobile station is in traffic state, the CDMA Module sends DTMF Message to

the Base Station and to the local audio path (speaker) at the same time. The network will deliver the

analog DTMF tone or DTMF Message to its final destination.
