DESCRIPTION:
The IDT72V70840 has a non-blocking switch capacity of 1,024 x 1,024
channels at 2.048 Mb/s, 2,048 x 2,048 channels at 4.096 Mb/s, and 4,096 x
4,096 channels at 8.192 Mb/s. With 32 inputs and 32 outputs, programmable
per stream control, and a variety of operating modes the IDT72V70840 is
designed for the TDM time slot interchange function in either voice or data
applications.
Some of the main features of the IDT72V70840 are low power 3.3 Volt
operation, automatic ST-BUS
