Description

•

Automatic frame offset delay measurement

Per-stream frame delay offset programming

Per-channel high impedance output control

Per-channel message mode

The MT90823 Large Digital Switch has

non-blocking switch capacity of: 2,048 x 2,048

channels at a serial bit rate of 8.192 Mb/s; 1,024 x

1,024 channels at 4.096 Mb/s; and 512 x 512

channels at 2.048 Mb/s. The device has many

features that are programmable on a per stream or

per channel basis, including message mode, input

offset delay and high impedance output control.

Control interface compatible to Motorola

non-multiplexed CPUs

•

Connection memory block programming

3.3V local I/O with 5V tolerant inputs and

TTL-compatible outputs

Per stream input delay control is particularly useful

for managing large multi-chip switches that transport

both voice channel and concatenated data channels.

•

IEEE-1149.1 (JTAG) Test Port

Applications

•

Medium and large switching platforms

In addition, the input stream can be individually

calibrated for input frame offset using a dedicated

pin.
