CMX909B Datasheet (Consumer Microcircuits Limited)

CMX909B, GMSK Packet Data Modem

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 mai
