Non
Input
CONTROL SIGNAL INPUT
Synchronous
Signal levels are LVCMOS/LVTTL compatible.
Used to select the output data bus width in SMPTE or Data-Through
modes. This signal is ignored in DVB-ASI mode.
When set HIGH, the parallel output will be 20-bit demultiplexed data.
When set LOW, the parallel outputs will be 10-bit multiplexed data.
