CML CMX990
the CMX990 provides the majority of circuits and functions to implement a full-feature ‘wireless modem’ subsystem. The CMX990 can operate in RF ranges of 400MHz to 1GHz at data rates of 4 to 16 kbps and is fully Mobitex compatible. With a minimum of external components and circuits, this half-duplex device provides on-chip: a flexible, formattable GMSK packet and free-format modem, a dual synthesiser, IF and RF stages for both Rx and Tx modes, and auxiliary ADCs and DACs for system control and monitoring.| Part No. | CMX990 |
