Description

Features:

• 16,384-channel x 16,384-channel non-blocking
   unidirectional switching.The Backplane and
   Local inputs and outputs can be combined to
   form a non-blocking switching matrix with 64
   stream inputs and 64 stream outputs.
• 8,192-channel x 8,192-channel non-blocking Backplane to Local stream switch.
• 8,192-channel x 8,192-channel non-blocking Local to Backplane stream switch.
• 8,192-channel x 8,192-channel non-blocking Backplane input to Backplane output switch.
• 8,192-channel x 8,192-channel non-blocking Local input to Local output stream switch.
• Rate conversion on all data paths, Backplane to Local, Local to Backplane, Backplane to
   Backplane and Local to Local streams.
• Backplane port accepts 32 ST-BUS streams with data rates of 2.048Mb/s, 4.096Mb/s,
   8.192Mb/s or 16.384Mb/s in any combination, or a fixed allocation of 16 streams at
   32.768Mb/s.
• Local port accepts 32 ST-BUS streams with data rates of 2.048Mb/s, 4.096Mb/s, 8.192Mb/s
   or 16.384Mb/s, in any combination.
• Per-stream channel and bit delay for Local input streams.
• Per-stream channel and bit delay for Backplane input streams.
• Per-stream advancement for Local output streams.
• Per-stream advancement for Backplane output streams.
• Constant throughput delay for frame integrity.
• Per-channel message mode for local and backplane output streams.
• Connection memory block programming for fast device initialization.
• BER testing for local and backplane ports.
• Automatic selection between ST-BUS and GCI-BUS operation.
• Non-multiplexed Motorola microprocessor interface.
• Conforms to the mandatory requirements of the IEEE-1149.1 (JTAG) standard.
• Memory Built-In-Self-Test (BIST), controlled via microprocessor registers.
• 1.8V core supply voltage.
• 3.3V I/O supply voltage.
• 5V tolerant inputs, outputs and I/Os.
• Per stream subrate switching at 4 bit, 2 bit and 1 bit depending on stream data rate.

Description

The MT90869 has two data ports, the Backplane and the Local port. The Backplane port has two modes of operation, either 32 input and 32 output streams operated at 2.048Mb/s, 4.096Mb/s, 8.192Mb/s or 16.384Mb/s, in any combination, or 16 input and 16 output streams operated at 32.768Mb/s. The Local port of MT90869 has 32 input and 32 output streams operated at 2.048Mb/s, 4.096Mb/s, 8.192Mb/s or 16.384Mb/s, in any combination.
