73M223
1200 Baud FSK Modem
February 1998
DESCRIPTION
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
to
implement
a
serial,
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.
asynchronous
data
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.
