Switch Fabric 256 x 256 3.3V 64-Pin TQFP Tray

The IDT72V70190 is a non-blocking digital switch that has a capacity of 256 x 256 channels at 2.048 Mb/s. Some of the main features are: programmable stream and channel control, Processor Mode, input offset delay and highimpedance 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.
