The 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 200kbps. Data Rates and the choice of BT (0.3 or 0.5) are pin programmable to provide for different system requirements.
