DESCRIPTION:
TheIDT72V73273hasanon-blockingswitchcapacityof 32,768x32,768
channels at 32.768Mb/s. With 64 inputs and 64 outputs, programmable per
stream control, and a variety of operating modes the IDT72V73273 is
designed for the TDM time slot interchange function in either voice or data
applications.
Some of the main features of the IDT72V73273 are LOW power 3.3 Volt
operation, automatic ST-BUS® /GCI sensing, memory block programming,
simple microprocessor interface , JTAG Test Access Port (TAP) and per
stream programmable input offset delay, variable or constant throughput
modes, output enable and processor mode, BER testing, bypass mode, and
advanced block programming.
