SEMICONDUCTOR TECHNICAL DATA

The MC145442 and MC145443 silicon–gate CMOS single–chip low–speed

modems contain a complete frequency shift keying (FSK) modulator, demodu-

lator, and filter. These devices are with CCITT V.21 (MC145442) and Bell 103

(MC145443) 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.
