CMX7163 QAM Modem

The CMX7163 QAM Modem is a half-duplex device supporting multiple channel spacings under host microcontroller (μC) control. Its *Function Image (FI) is loaded to initialise the device and determine modulation types. The7163 FI-4.x supports 4-, 16- and 64-QAM modulations, root raised cosine filtered with =0.2, 0.35 or a user programmable filter. The7163 FI-4.
