DESCRIPTION:
The IDT72V70800 is a non-blocking digital switch that has a capacity of
512 x 512 channels at a serial bit rate of 8.192 Mb/s. Some of the main features
are: programmable stream and channel control, Processor Mode, input offset
delay and high-impedance output control.
Per-stream input delay control is provided for managing large multi-chip
switches that transport both voice channel and concatenated data channels. In
addition, input streams can be individually calibrated for input frame offset.
