2. Overview
2.1 Application Descriptions
The CDMA Wireless Data Modem is a complex consumer communications instrument that relies
heavily on both digital signal and embedded processor technologies. The Wireless Data Modem
manufactured by AnyDATA.NET supports Code-Division-Multiple-Access(CDMA). This operates in
PCS spectrum.
In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data
Modem, AnyDATA.NET has successfully developed the EMII-800. The EMII-800 is AnyDATA.NET–s
latest compact Wireless Data Modem operating in PCS spectrum, also contains complete digital
modulation and demodulation system for CDMA standards as specified in IS-95 A/B and IS-2000.
The subsystem within the EMII-800 includes a CDMA processor (MSM5100), an integrated
CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward
link data communications of a rate of 153.6kbps.
The EMII-800 provides external interface. External interface includes the standard RS-232, Digital
Audio, and External On/Off control.
The EMII-800 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 design the EMII-800 into a subscriber unit application.
In addition, the internal signals that are necessary for complete understanding of the UART interfaces are
described below.
4.2 RS232 Interface (Standard)
The Universal Asynchronous Receiver Transmitter (UART) communicates with serial data that
conforms the RS-232 Interface protocol. The modem provides 3.0V CMOS level outputs and 3.0V
CMOS switching input level. And all inputs have 5.0V tolerance but 3.0V or 3.3VCMOS logic
compatible signals are highly recommended.
All the control signals of the RS-232 signals are active low, but data signals of RXD, and TXD Are
active high. The UART has a 64byte transmit (TX) FIFO and a 64byte receive (RX) FIFO. The UART
Features hardware handshaking, programmable data sizes, programmable stop bits, and odd, even, no
parity. The UART operates at a 115.2kbps maximum bit rate.
