Description

Sub-rate switching (2 or 4 bits) conﬁguration for

local streams at a data rate of 2.048Mb/s

The MT90866 Digital Switch provides switching

capacities of 4,096 x 2,432 channels between

backplane and local streams, 2,432

Per-channel variable or constant throughput

delay

2,432

channels among local streams and 2,048 x 2,048

channels among backplane streams. The local

connected serial inputs and outputs have 32, 64 and

128 64kb/s channels per frame with data rates of

2.048, 4.096 and 8.192Mb/s respectively. The

backplane connected serial inputs and outputs have

128 and 256 64kb/s channels per frame with data

rates of 8.192 and 16.384Mb/s respectively.

•

Fully compliant to H.110 Timing speciﬁcations

Automatic frame offset delay measurement for

backplane streams

•

Per-stream input frame delay offset, up to 128

bytes, programmable for local streams on a per

quarter bit or per channel basis

•

Per-stream output frame advancement,

programmable for backplane and local streams

The MT90866 also offers a sub-rate switching

conﬁguration which allows 2-bit wide 16kb/s or 4-bit

wide 32kb/s data channels to be switched within the

device.

Per-channel direction control for backplane

streams

Per-channel message mode for backplane and

local streams

Per-channel high impedance output control for

backplane and local streams

The device has features that are programmable on

per-stream or per-channel basis including message

mode, input delay offset, output advancement offset,

direction control and high impedance output control.

Pseudo-Random Binary Sequence (PRBS)

pattern generation and testing for backplane

and local streams

•

5V tolerant PCI driver on CT-Bus I/O’s

Integrated PLL, compatible to Stratum 4

Enhanced clock switching standard

•

Non-multiplexed microprocessor interface

Connection memory block programming for fast

device initialization

•

Tristate-control outputs for external drivers

Conform to the mandatory requirements of the

IEEE-1149.1 (JTAG) standard
