MT90210 Datasheet Multi-rate Parallel ACcess Circuit

Manufacturer: Mitel Networks Corporation

Overview: MT90210 Multi-Rate Parallel Access Circuit Preliminary Information.

General Description

The MT90210 is a 100-pin device used to interface a parallel bidirectional 8 bit bus to 24 time division multiplexed (TDM) serial streams.

The device is configured to perform simultaneous parallel-to-serial and serial-to-parallel conversion with the capability of handling up to 3072 channels, 1536 on the transmit and 1536 on the receive direction.

Depending on the operation mode selected at the mode pins, the individual 64 Kb/s channels on the serial links may be configured as inputs or outputs.

Key Features

  • Parallel-to-serial and serial-to-parallel conversion of up to 1536 full duplex channels or 3072 time-slots Serial port data rates selectable between 2.048, 4.096 or 8.192 Mb/s Provides a mechanism for a double buffer function to be implemented in external memory 24 serial I/O lines programmable in different modes: 12 in/12 out at 8.192 Mb/s (1536 full duplex channels) or 24 bidirectional line modes for 2.048 and 4.096 Mb/s Provides a bidirectional 8-bit parallel port operating at 16.38.
