Interface Description EMIII-DUAL Reference Manual Application Information EMIII-DUAL V1.0 AnyDATA.NET Proprietary – Use Subject to Restrictions 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 EMIII-DUAL. The EMIII-DUAL 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 EMIII-DUAL 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 EMIII-DUAL provides external interface. External interface includes the standard RS-232, Digital Audio, and External On/Off control. The EMIII-DUAL has the capability to power down unused circuits in order to dynamically minimize power consumption.

Interface Descriptions 4.1 Overview This chapter covers information required to design the EMIII-DUAL 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.
