Product Summary
73K324L-28IHR is a highly integrated single-chipmodem IC, which provides the functions, needed to design a Quad-mode CCITT and Bell 212A compatible modem capable of operation over dial-up lines. The 73K324L-28IHR adds V.23 capability to the CCITT modes of TERIDIAN Semiconductor Corporation 73K224 one-chip modem, allowing a one-chip implementation in designs intended for European markets, which require this added Modulation mode. The 73K324L-28IHR offers excellent performance and a high level of functional integration in a single IC.
