CML Microcircuits CMX869
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. 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.- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

DESCRIPTION
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. 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 µController. Control of the device is via a simple high speed serial bus that operates in normal and Powersave modes, and is compatible with most types of µC serial interface.
