MT9085

• Configurable for parallel-to-serial or serial-to-parallel conversion of 1024 channels
• Interfaces to Mitel's MT9080 Switch Matrix Module (SMX). Generates all framing signals required in 1K or 2K switching applications
• Serial data rates of 2.048 Mbit/s or 4.096 Mbit/s
• Mitel ST-BUSä compatible serial inputs/outputs

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 Mitel MT9080 (SMX) and output it on 32/16 time division multiplexed serial bus streams. A second device of MT9085 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 of MT9085 generates all framing signals required by the SMX for 1024 and 2048 channel configurations.
