Single–Chip 300–Baud Modem  
Legacy Device: Motorola MC145442B, MC145443B  
The ML145442 and ML145443 silicon–gate CMOS single–chip low–speed  
modems contain a complete frequency shift keying (FSK) modulator, demod-  
ulator, and filter. These devices are compatible with CCITT V.21 (ML145442)  
and Bell 103 (ML145443) specifications. Both devices provide full–duplex or  
half–duplex 300–baud data communication over a pair of telephone lines.  
They also include a carrier detect circuit for the demodulator section and a  
duplexer circuit for direct operation on a telephone line through a simple  
transformer.
