DESCRIPTION
The 73K212AL is a highly integrated single-chip modem IC which provides the functions needed to construct a typical Bell 212A full-duplex modem. Using an advanced
CMOS process that integrates analog, digital and switched-capacitor filter functions on a single substrate, the 73K212AL offers excellent performance and a high level of functional integration in a single 28-pin DIP or PLCC package. The 73K212AL operates from a single +5V supply. The 73K212AL is a new version replacing the 73K212L. The 73K212AL should be specified for all new designs.
The 73K212AL includes the DPSK and FSK modulator/demodulator functions, call progress and handshake tone monitor test modes and a DTMF dialer. This device supports all Bell 212A modes of operation allowing both synchronous and asychronous communications.
Test features such as analog loop, digital loop, and remote digital loopback are provided. Internal pattern generators are also included for self-testing. The 73K212AL is designed to...
