CMX644AD2 - V.22 and Bell 212A Modem - CML Microcircuits

The CMX644A V.22 modem is intended for use in any telephone based information and telemetry system with

low power requirements. Using V.22 signalling, fast call set up times and robust error resistant transmission

can be implemented by efficient low power circuits. The circuit can operate at 1200b/s full duplex over 2-or 4-

wire circuits. Control of the device is via a simple high speed serial bus and data may be optionally formatted

by the on-chip UART. This allows easy interfacing to a host µController. The data transmitted and received

by the modem is also transferred over the same high speed serial bus. In addition to V.22, support is included

to meet the Bell 212A standard. The integrated DTMF encoder can be used as part of the dial out function.

All 16 DTMF combinations are available along with a single tone ‘melody’ mode.
