Introduction
The PT7D5820/5820L is a Large Digital Switch (LDS).
It provides 2,048 x 2,048 channel non-blocking switching
among 16 input streams and 16 output streams at most.
Its serial bit rate can be 8.192Mb/s, 4.096Mb/s or
2.048Mb/s.
The device has many features that are programmable
on stream or channel basis, including message mode,
input offset delay and high impedance output control.
Per steam input delay control is particularly useful
for managing large multi-chip switches that transport
both voice channel and concatenated data channels.
In addition, input stream can be individually
calibrated for input frame offset using a dedicated
pin.
