Multi-Mode Wireless Data Modem IC
RFMW announced design and sales support for CML Microcircuits’ CMX7164. The CMX7164 is a half-duplex, multi-mode wireless Data Modem supporting 4/16/32/64 QAM, 2/4/8/16 FSK, GMSK/GFSK and V.23 modes, in multiple channel spacings, under host control. An integrated analog interface supports direct connection to zero-IF I/Q radio transceivers with few external components; no external codecs are required. Intelligent auxiliary ADC, DAC and GPIO sub-systems perform valuable functions and minimize host interaction and host I/O resources. Two synthesized system clock generators develop clock signals for off-chip use. Differential inputs are ideal for direct connection to RF direct conversion receiver ICs.
