Description
The
non-blocking switch capacity of 2,048 x 2,048
channels at a serial bit rate of 8.192Mb/s, 1,024 x
1,024 channels at 4.096Mb/s and 512 x 512
channels at 2.048Mb/s. The device has many
features that are programmable on per stream or per
channel basis, including message mode, input offset
delay and high impedance output control.

Per stream 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.
