A ST-BUS® compatible digital switch controlled by a
microprocessor which can handle from 128 x 128 to 32K x 32K inputs to multiple outputs.

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.
