Product Summary

The 73K222AL-IP is a highly integrated single-chip modem IC which provides the functions needed to construct a CCITT V.22, V.21 and Bell 212A compatible modem, capable of 1200 bit/s full-duplex operation over dial-up lines. In Bell 212A mode, the 73K222AL provides the normal Bell 212A and 103 functions and employs a 2225 Hz answer tone. The 73K222AL in V.22 mode produces either 550 or 1800Hz guard tone, recognizes and generates a 2100 Hz answer tone, and allows 600 bit/s V.22 or 0-300 bit/s V.21 operation. The 73K222AL integrates analog, digital, and switched-capacitor array functions on a single substrate, offering excellent performance and a high level of functional integration in a single 28-pin DIP, PLCC and 44-pin TQFP configuration. The 73K222AL operates from a single +5V supply.
