ML145443

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 (ML145442)

.21

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.

This Device Offers The Following Performance Features:

•

ML145442 Compatible with CCITT V

.21

ML145443 Compatible with Bell 103

Low–Band and High–Band Band–Pass Filters On–Chip

Simplex, Half–Duplex, and Full–Duplex Operation

Originate and Answer Mode

Analog Loopback Configuration for Self Test

Hybrid Network Function On–Chip

Carrier Detect Circuit On–Chip

Adjustable Transmit Level and CD Delay Timing

On–Chip Crystal Oscillator (3.579 MHz)

Single +5 V Power Supply Operation

Internal Mid–Supply Generator

Power–Down Mode

Pin Compatible with MM74HC943

Capable of Driving –9 dBm into a 600 W Load

Operating Temperature Range = TA –40° to +85°C
