CMX909B Overview
The CMX909B is a half-duplex Gaussian Minimum Shift Keyed (GMSK) BT=0.3 modem data pump with on-chip packet data handling. GMSK modulation optimises the data throughput for a given bandwidth RF channel and the on-chip packet data handling relieves the host µC of regular processing tasks, such as maintaining Bit and Frame Synchronisation, Block Formatting, CRC and FEC Error Processing, Data Interleaving and...
