General Description
The CMX624 contains a Bell 202 and V.23 compatible FSK modem. This device is capable of duplex operation at 1200/75bps or 1200/150bps over a 2-wire line interface. It is also capable of 1200/1200bps over a 4-wire line interface. This device also contains a flexible FSK data UART, a receive FSK or Call Progress Tone energy detector, a 2100Hz detector, a DTMF generator, a Tx line driving buffer amplifier, a telephone line Ringing Signal or Line Voltage Reversal detector and a 3.579545MHz Xtal oscillator. These functions are controlled via a serial interface to the µC, which also carries the transmit and receive FSK modem data.
