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
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.
The data on the parallel bus is in a format suitable for
interfacing with a dual-port RAM. Depending on the
data rate selected by the MD0-MD2 input pins, serial
data is clocked in and out on the serial streams at
either 2.048, 4.096 or 8.192 Mb/s.
