15.4. WORD CLOCK PHASE ALIGNMENT TO VIDEO
Whenever mathematically possible, the DCD-24 will achieve accurate alignment
between the vertical sync of the incoming video and the rising edge of the output
wordclock. Accuracy is per the original AES requirement of 5% of the sample
clock period. This phase adjustment begins immediately after intial lock has been
achieved. Please allow up to 30 seconds for this state to be realized.
The table below indicates when alignment will occur between the input video “refer
-
ence point” (vertical sync) and the output wordclock rising edge.
