UX-68DE FO-78DE (4) Modem (FM209V) block FEATURES INTRODUCTION • The CONEXANT FM209V MONOFAX modem is a synchronous 9600 bits per second (bps) half-duplex modem with error detection and DTMF reception. It has low power consumption and requires a single +5V and +3.3V DC power supply. The modem is housed in a single VLSI device package. The modem can operate over the public switched telephone network (PSTN) through line terminations provided by a data access arrangement (DAA).
