Low Power V.32 Bis Modem

The CMX869 is a multi-standard modem for use in telephone based information and telemetry systems. It CAN also transmit and detect standard DTMF and modem calling and answer signals and user-specific programmed single or dual Tone signals. A general purpose Call Progress signal detector is also included. Flexible Line Driver and receive hybrid circuits are integrated on chip, requiring only passive external components to build a 2 or 4-wire line Interface The device also features a software controlled hook Switch Relay Drive output and a Ring Detector circuit, which continue to function when the device is in the Powersave mode. When a line voltage reversal or ringing signal is detected, the Ring Detect Circuit CAN provide an interrupt which CAN be used to wake up the host Controller. By Consumer Microcircuits Limited
