CMX589AE2CML Innovative TechnologiesFULL-DUPLEX GMSK DATA MODEM62 X TUBE ROHSALSO AVAILABLE ON TAPE5A991GDescriptionThe CMX589A is a single-chip synchronous data pump/modem designed for Wireless Data Applications. Employing Gaussian filtering for Minimum shift Keying (GMSK) baseband modulation applications, the CMX589A features a wide range of available data rates from 4k to 200k bps. Data Rates and the choice of BT (0.3 or 0.5) are pin programmable to provide for different system requirements. The Tx and Rx digital data interfaces are bit serial, synchronized to generated Tx and Rx data clocks. Separate Tx and Rx Powersave inputs allow full or half-duplex operation. Rx input levels can be set by suitable AC and DC level adjusting circuitry built with external components around an on-chip Rx Input Amplifier.Acquisition, Lock, and Hold of Rx data signals are made easier and faster by the use of Rx Control Inputs to clamp, detect, and /or hold input data levels and can be set by the mProcessor as required. The Rx S/N output provides an indication of the quality of the received signal. The CMX589A may be used with a 3.0V to 5.5V power supply and is available in the following packages: 24-pin TSSOP (CMX589AE2), 24-pin SSOP (CMX589AD5), 24-pin SOIC (CMX589AD2), and 24-pin PDIP (CMX589AP4).
