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 di...
