SSI73M223

The SSI73M223 is a kind of modem device. SSI73M223 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, asynchronous data communication channel. SSI73M223 is intended for half duplex operation over a two-line system. Besides, it is suitable for RF data links, credit verification systems, point-of-state terminals, and remote process control.

There are some features of SSI73M223 as follows: (1)low cost FSK modem; (2)1200 baud operation; (3)CMOS switched capacitor technology; (4)built-in self-test feature; (5)on-chip filtering, and modulation/demodulation; (6)uses CCITT V.23 frequencies; (7)on chip crystal oscillator; (8)low power/high reliability; (9)16-pin plastic packages.

The following is about the absolute maximum ratings of SSI73M223: (1)power supply voltage, VDD-VSS: 14 V; (2)analog input voltage at RXA: -0.3 to VDD V; (3)analog input voltage at RXF: -3 to VDD V; (4)digital input voltage: VSS-0.3 to VDD+0.3 V; (5)storage temperature range: -65 to +150; (6)operating temperature range: -25 to +70; (7)lead temperature (10 secs soldering): 260.
