4.4.3 Serial Digital Output Mute
4.5 Serial-To-Parallel Conversion
The GS1559 will automatically mute the serial digital loop-through output in both
master and slave modes when the internal carrier_detect signal indicates an
invalid serial input.
The loop-through output will also be muted in slave mode when SDO/SDO is
selected as reclocked, (RC_BYP = HIGH), but the lock detect block has failed to
lock to the data stream, (LOCKED = LOW).
Table 4-1
data stream.
Table 4-1: Serial Digital Loop-Through Output Status
The retimed data and phase-locked clock signals from the reclocker are fed to the
serial-to-parallel converter. The function of this block is to extract 10-bit or 20-bit
parallel data words from the reclocked serial data stream and present them to the
SMPTE and DVB-ASI word alignment blocks simultaneously.
