2. Overview
2.1Application Descriptions
The CDMA Wireless Data Module is acomplexconsumer communications instrument that relies
heavilyonbothdigital signal and embedded processortechnologies. TheWirelessData Modules
manufacturedbyAnyDATA.NET support Code-Division Multiple Access (CDMA). This operates in
both the cellular and PCS spectrum.
Inacontinuing effort tosimplifythe designandtoreduce theproductioncost oftheWireless Data
Module, AnyDATA.NEThas successfullydevelopedthe DT2000series. The DT2000-Dualis
AnyDATA.NET slatest compact Wireless Data Module operatingin the CellularandPCS spectrum. The
DT2000-Dual alsocontains a complete digital modulationand demodulation system forCDMA standards
as specifiedin IS-95 A/Band IS-2000.
The subsystemintheDT2000-Dual includesaCDMA processor(MSM5100),an integrated
CODEC withanearpiece and microphoneamplifiers, andan RS-232serial interface supportingforward
link data communications at a rate of 230.4kbps.
The DT2000-Dual provides an external interface that includes the standardRS-232,Digital Audio,
External reset control, LCD Display, Keypad, andRingerextension ports.
The DT2000-Dual hasthecapabilityto powerdown unusedcircuits inorder todynamically
minimize power consumption.
