72V70180数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The IDT72V70180 is a non-blocking digital switch that has a capacity of 128 x 128 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.
