Description

•

Compatible to HMVIP and H.100 speciﬁcations

Automatic frame offset delay measurement

Per-stream frame delay offset programming

Per-channel message mode

The MT90863 Rate Conversion Switch provides

switching capacities of 2,048 × 512 channels

between backplane and local streams, and 512 x

512 channels for local streams. The connected serial

inputs and outputs may have 32, 64 and 128 64kb/s

channels per frame with data rates of 2.048Mb/s,

4.096Mb/s and 8.192Mb/s respectively.

Per-channel direction control

Per-channel high impedance output control

Non-multiplexed microprocessor interface

Connection memory block programming

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

TTL-compatible outputs

The MT90863 also offers a sub-rate switching

conﬁguration which allows 2-bit wide 16kb/s data

channels to be switched within the device.

•

IEEE-1149.1 (JTAG) Test Port

Applications
