Description
The MT9085 Parallel Access Circuit (PAC) provides an
interface between an 8 bit, parallel time division
multiplexed bus and a serial time division multiplexed
bus. A single PAC device will accept data clocked out
on the parallel bus of the Zarlink 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.
