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
V2.0 is AnyDATA.NET’s latest compact Wireless Data Module operating in the Cellular and PCS
spectrum band. The DTG2000-Dual V2.0 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 V2.0 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 V2.0 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

4. Interface Descriptions
4.1 Overview
This chapter covers information required to convert the DTG2000-Dual V2.0 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 V2.0 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-Dual V2.0.
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-Dual V2.0 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 (Pin88 and 90).

4.2.2 Supply Input to BATT_INT (Pin 88 and Pin 90)
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 88 and 90) is recommended.
When the input voltage from +3.4V to +4.3V is supplied to BATT_INT(Pin88 and 90), DTG2000-Dual
V2.0 won’t automatically start its power-on process without low assertion of POWER_ON (Pin 30). To
power the module on, first apply VCC to BATT_INT and have POWER_ON (Pin30) stay low for more
than 500 msec and less than 2 sec.
POWER_ON (Pin 30) needs to be externally pulled up to 3V to 3.6V thru 100kohm resistor.
To power off the module, have POWER_ON(Pin 30) 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(Pin88 and 90), 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 30)
won’t power on or off the module or Pin 31(Ext_Reset) may not work.
If Vcc is supplied directly from a battery, having a FET between the output of a battery and input of
DTG2000-Dual V2.0 is recommended that the customer can shut off the Vcc to DTG2000-Dual V2.0
using the FET as a reset method..
4.3 CODEC Interface
With the integrated microphone and earpiece amplifier including CODEC, the DTG2000-Dual V2.0
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

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 DTG2000-Dual V2.0 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.
