73K224BL V.22bis/V.22/V.21/Bell 212A/103 Single-Chip Modem w/ Integrated Hybrid DESCRIPTION The 73K224BL is a highly integrated single-chip modem IC which provides the functions needed to construct a V.22bis compatible modem, capable of 2400 bit/s full-duplex operation over dial-up lines. The 73K224BL is an enhancement of the 73K224L single-chip modem which adds the hybrid hook switch control, and driver to the 73K224L. The 73K224BL integrates analog, digital, and switchedcapacitor array functions on a single chip, offering excellent performance and a high level of functional integration in a 32-Lead PLCC and 44-Lead TQFP package. The 73K224BL operates from a single +5 V supply for low power consumption.
