Description
The device has sixteen ST-BUS inputs (STi0-15) and sixteen ST-BUS outputs (STo0-15). It is a non-blocking digital
switch with 512 64 kb/s channels and performs rate conversion between the ST-BUS inputs and ST-BUS outputs.
The ST-BUS inputs accept serial input data streams with the data rate of 2.048 Mb/s, 4.096 Mb/s or 8.192 Mb/s on
a per-stream basis. The ST-BUS outputs deliver serial output data streams with the data rate of 2.048 Mb/s,
4.096 Mb/s or 8.192 Mb/s on a per-stream basis. The device also provides sixteen high impedance control outputs
(STOHZ 0-15) to support the use of external high impedance control buffers.
The ZL50012 has features that are programmable on per-stream or per-channel basis including message mode,
input bit delay, output bit advancement, constant throughput delay and high impedance output control.
