Output Data Definition and Timing

2.2.3.1

Timing for all output types

CLK+ *
OUTx +/- **
For I/Q merged output, RS CADU output and LDPC CADU output:
t = 1/2BR - 500 ps
s
t = 1/2BR - 500 ps
h
For normal I and Q outputs:
t = 1/BR - 500 ps
s
t = 1/BR - 500 ps
h
* Clock polarity: Normal Output Clock
** Except when OUT3 = CLK
Remark: For data output after specific decoding process (example: TCM + RS-DVB, punctured
Viterbi), "holes" inside the output data and clock signals can be present. These "holes" are due to the
delayed check symbols and / or synchronization words. Nevertheless it has to be considered that for
each data corresponds an edge of the clock.
