Product Summary
The MC145443P silicon–gate CMOS single–chip low–speed modem contains a complete frequency shift keying (FSK) modulator, demodulator, and filter. It is with Bell 103 specification. The MC145443P provides full–duplex or half–duplex 300–baud data communication over a pair of telephone lines. It also includes a carrier detect circuit for the demodulator section and a duplexer circuit for direct operation on a telephone line through a simple transformer.
