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 DTEV-series. The DTEV-Dual is

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

DTEV-Dual contains not only a complete digital modulation and demodulation system for CDMA

standards as specified in IS-95 A/B, IS-2000 , IS-856 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 DTEV-Dual includes a CDMA processor MSM6500™ chipset’s multimedia

support for MP3 player and integrated stereo HiFi audio DAC, 64-polyphony MIDI sound synthesizer and

PC-quality wavetable , MMC Mobile™ , USB-On-The-Go transceiver, Stereo Wireband Codec for digital

music clips.

DTEV-Dual supports CDMA2000 1X, Release A standard, offering data rate of up to 153 kbps on

both the forward and reverse links, along with simultaneous voice and data services, and IS-856 1xEV-DO

for high speed data rate of 2.4Mbps on forward link and 153Kbps on reverse link.

The fast system in DTEV-Dual includes 256Mbytes NAND Flash Memory and 256Mbytes

synchronous high data rate Dynamic RAM.

DTEV-Dual provides an external interface that includes the standard RS-232, Digital Audio, parallel

LCD Display, Keypad, Multimedia Card, R-UIM/USIM, USB-OTG, GPIO.

DTEV-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 DTEV-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 DTEV-Dual as shown in the following

figure. These blocks include:

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 DTEV-Dual module.

4.2.1 External Supply

If the customers don’t need to save current in sleep mode, which is around 10mA, supplying voltage to

VEXT_DC (Pin 87 and Pin89) is recommended. When the input voltage from +4V to +5.25V is supplied,

DTEV-Dual 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 +5.0V DC to VEXT_DC(Pin87

and Pin89) and connect a +3.6V 1-cell lithium-ion battery to BATT_INT(Pin88 and 90).

Table 4-1 Eternal Supply Pinouts

Pin # Pin Name Main Function Type Description

87 VEXT_DC VEXT_DC I External DC input

89 VEXT_DC VEXT_DC I

External DC input

4.2.2 Keypad Power On and Supply Input to BATT_INT

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

voltage to BATT_INT (Pin 88 and 90) is recommended.

When the input voltage from +3.3V to +4.5V is supplied to BATT_INT (Pin88 and 90) and

POWER_ON goes to Low from High, power on sequence is initialed. For a successful power on sequence,

POWER_ON(Pin30) must stay Low for more than 500msec and less than 2sec).

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 or a DC/DC converter to BATT_INT(Pin88 and 90), using

one 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. If Vcc is supplied directly from a battery, having

a FET between the output of a battery and VBATT_INT(Pin88 and Pin90) is recommended that the

customer can shut off the power to DTEV-Dual using the FET switch.

4.3 Power Down Registration Protocol for CDMA device

Before DTEV-Dual 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 up to 12 seconds according to CDMA technical standard.

4.4 Stereo Wideband CODEC Interface

With the integrated microphone and earpiece amplifier including CODEC, the DTEV-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.

4.4.1 Microphone and earphone 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 module supports audio outputs with its variable gain audio as volume control can be used for

audio alerts or speaker phone. The speaker driver has programmable gain, turn-on time, and muting, and

operates as a differential device delivering a volume-controlled 500mW to an external 8-Ohm speaker.

The EAR10 and MIC1P are typically used for the handset ear-piece/mic.

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

* 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_DET 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

LOW signal to the EAR_DET pin for as long as the user wants the audio path thru ear-jack to be kept

open

4.7.2 MultiMediaCard controller

DTEV-Dual contains a MultiMediaCard (MMC) controller that provides a link between the

ARM bus master and the MultiMediaCard bus for storing digital music, games, address books and photos.

The SD card supports a 1-bit SD bi-directional bus mode. SD bus pins are CLK, CMD and DAT in 1-bit

mode and CLK, CMD, and DAT[0:3] in 4-bit mode. The MultiMediaCard also supports the 1-bit bi-

directional MMC bus mode that has CLK, CMD, and DAT bus pins. The CMD and DAT pins are bi-

directional on the SD 1-bit, SD 4-bit, and MMC 1-bit. DTEV-Dual can’t support SD 4-bit mode. MMC
