73K324L
CCITT V.22bis, V.22, V.21, V.23, Bell 212A
Single-Chip Modem
April 2000
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
microcontrollers (80C51 typical) for control of
modem functions through its 8-bit multiplexed
address/data bus. A serial control bus is available
for applications not requiring a parallel interface. An
optional package with only the serial control bus is
also available. Data communications occurs through
a separate serial port.
