73K324L

73K324L CCITT V.22bis, V.22, V.21, V.23, Bell 212A Single-Chip Modem DESCRIPTION The 73K324L is a highly integrated single-chip modem 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 adds V.23 capability to the CCITT modes of TDK Semiconductor Corporation's 73K224 one-chip modem, allowing a one-chip implementation in designs intended for European markets which require this added Modulation mode. The 73K324L offers excellent performance and a high level of functional integration in a single IC. The device supports V.22bis, V.22, Bell 212A, V.21, and V.23 operating modes, allowing both synchronous and asynchronous operation as defined by the appropriate standard. The 73K324L is designed to appear to the Systems Engineer as a microprocessor peripheral, and will easily interface with popular one-chip microcontrollers (80C51 typical) for control of modem functions through its 8-bit mu...
