CMX7164 - Multi Mode Modem

Description

The CMX7164 Multi Mode Modem is a half-duplex device currently supporting GMSK/GFSK, 4/16/32/64QAM, 2/4/8/16-Level FSK and V.23 modes in multiple channel spacings under host control.

Function Image (FI) is loaded to initialise the device and determine modulation types.

Features

  • Half-duplex modem supports multiple modulations and channel spacings.
  • 7164FI-1.x o GMSK/GFSK with BT=0.5, 0.3, 0.27 or 0.25 o Over-air compatible with FX/MX909B and CMX7143FI-1.x o Two frame sync detectors o Automatic frame sync detect o Rx carrier frequency correction o Receive signal quality measurement.
  • 7164FI-2.x o 2/4/8/16-FSK up to 10ksymbols/s in 25kHz e. g. 40kbps for 16-FSK o Compatible FEC for CMX7143 and FX/MX919B 4-FSK (not 2-FSK) o Over-air compatibility w.
