PAC - Parallel Access Circuit

ISSUE 3

January 1993

Features

•

Configurable for parallel-to-serial or

serial-to-parallel conversion of 1024 channels

Ordering Information

MT9085AP

68 Pin PLCC

•

Interfaces to Mitel’s MT9080 Switch Matrix

Module (SMX). Generates all framing signals

required in 1K or 2K switching applications

-40°C to 70°C

•

Serial data rates of 2.048 Mbit/s or 4.096 Mbit/s

Mitel ST-BUS compatible serial inputs/outputs

Description

The MT9085 Parallel Access Circuit (PAC) provides

an interface between an 8 bit, parallel time division

multiplexed bus and

serial time division

Applications

multiplexed bus. A single PAC device will accept

data clocked out on the parallel bus of the Mitel

MT9080 (SMX) and output it on 32/16 time division

multiplexed serial bus streams. A second device can

be configured to perform the conversion from the

serial format into an SMX compatible parallel format.

The time division, serial multiplexed streams may

operate at 2.048 Mbit/s or at 4.096 Mbit/s. The PAC

generates all framing signals required by the SMX

for 1024 and 2048 channel configurations.
