SYNC REGENERATION
The hsync regeneration reproduces a regular hsync, e.g.
in case of equalizing pulses or an absent hsync during
vsync. The input selection is shown in Table 23.

ELECTION OF SYNCS FOR LINE
-
LOCKED
PLL
The source signals of the line-locked PLL are selected
according to Table 24 as either HSYNC and VSYNC from
the input pins or the composite sync decoder outputs
HS_CS and VS_CS.

ELECTION OF SYNCS FOR MODE DETECTION AND
INPUT INTERFACE
The output selection for input interface and mode
detection allows to choose between the input signals
HSYNC and VSYNC, composite sync decoder outputs
HS_CS and VS_CS and the syncs decoded from the DVI
input HS_DVI and VS_DVI. The regenerated hsync
HS_REGEN can be selected as source
(see Tables 25 and 26).
