描述 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.

特性 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 16.384 or 32.768 MByte/s for direct interface to external memory (dual port)

• Provides an external 13-bit output address bus for direct connection with an 8K-position dual port memory

• JTAG boundary scan

Applications

• Fast access to ST-BUS, SCSA, MVIP, and H-MVIP serial backplanes

• Voice processing cards for Computer Telephony Integration (CTI)

• Video and teleconferencing bridge cards

• Fast DSP access to serial TDM buses
