MT90840

Distributed Hyperchannel Switch

Advance Information

ISSUE 1

June 1995

Features

•

Time-slot interchange function between 8 pairs

of ST-BUS/GCI/MVIP streams (512 channels)

and a Parallel Data Port (PDP)

Ordering Information

MT90840AK

MT90840AP

100 Pin PQFP

84 Pin PLCC

Supports star, point to point connections and

unidirectional or bidirectional ring topologies for

distributed systems

-40°C to 85°C

•

Input to Output Bypass function with minimum

delay for shared ring applications

•

Special diagnostic alarm functions for statistical

analysis

Provides an internal latency adjustment buffer

for ring applications

JTAG boundary scan

Applications

•

Parallel port data rates up to 19.44Mbyte/s

•

Bridging ST-BUS/MVIP buses to high speed

Time Division Multiplex backplanes at SONET

rates (STS-1/3)

Programmable data rates on the serial port side

(2.048 Mb/s, 4.096 Mb/s or 8.192 Mb/s)

•

Unidirectional Parallel switching mode for up to

2430 channels non-blocking

High speed isochronous backbones for

distributed PBX and Local Area Network

systems

Per-channel direction control on the serial port

side

Switch platforms of up to 2430 channels with

guaranteed frame integrity for wideband

channels

Per-channel message mode and high-

impedance control on both parallel and serial

port sides

•

Serial bus control and monitoring

Data multiplexer

•

8-bit multiplexed port compatible with Intel and

Motorola microcontrollers

Guarantees frame integrity when switching

wideband channels such as ISDN H0 channel

High speed communications interface

Isochronous switching/multiplexing to support

IEEE 802.9 standards

Provides external control lines allowing the fast

parallel interface to be shared with other

devices
