DESCRIPTION:
The IDT72V73260 has a non-blocking switch capacity of 16,384 x 16,384
channels at 32.768Mb/s. With 32 inputs and 32 outputs, programmable per
stream control, and a variety of operating modes the IDT72V73260 is designed
for the TDM time slot interchange function in either voice or data applications.
Some of the main features of the IDT72V73260 are LOW power 3.3 Volt
operation, automatic ST-BUS
廬
/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.
