73M223

1200 Baud FSK Modem

February 1998

DESCRIPTION

FEATURES

The 73M223 modem device receives and transmits

serial and binary data over existing telephone

networks using Frequency Shift Keying (FSK). It

provides the filtering, modulation, and demodulation

•

Low cost FSK Modem

1200 baud operation

CMOS switched capacitor technology

Built-in self-test feature

to implement

serial, asynchronous data

communication channel. The 73M223 employs the

CCITT V.23 signaling frequencies of 1302 and 2097

Hz, operating at 1200 baud, and is intended for half

duplex operation over a two-line system.

On-chip filtering, and

Modulation/Demodulation

•

Uses CCITT V.23 frequencies

On chip crystal oscillator

Low power/High reliability

Does not require a microprocessor

10 mW @ 5 V supply

The 73M223 provides a cost-effective alternative to

existing modem solutions. It is ideally suited for R.F.

data links, credit verification systems, point-of-sale

terminals, and remote process control.

CMOS technology ensures small size, low-power

consumption and enhanced reliability.
