Figure 12: QVCP and FGPO I/O Timing
See timing measurement conditions
Timing applies when the data is output on a positive or a negative edge in double edge clock
mode, see
If the VDO_CLK[1,2] is inverted internally then the timing applies to the negative edge.
Timing applies for VDO_D[29], FGPO_REC_SYNC and FGPO_BUF_SYNC. VDO_D[29]
and FGPO_BUF_SYNC. This inputs are assumed asynchronous.
In double edge clock mode, the maximum VDO_CLK1 frequency is lower than in single edge
clock mode. Refer to
The SAA7104H/5H input hold time specification for the data lines, PD[11:0], is actually 1.2
ns. The SAA7104H/5H input hold time specification for the xSVGC lines (SYNC signals)
remains 1.5 ns; therefore traces on the board should compensate for the missing 0.3 ns
delay.
