Single–Chip 300–Baud Modem

Legacy Device: Motorola MC145442B, MC145443B The ML145442 and ML145443 silicongate CMOS singlechip lowspeed 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 fullduplex or halfduplex 300baud 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. By Lansdale Semiconductor, Inc.
