DESCRIPTION:
The IDT72V70200 is a non-blocking digital switch that has a capacity of
512 x 512 channels at 2.048 Mb/s. Some of the main features are: program-
mable 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.
