Description
*****0**
Bit 2—Output Vsync Select. Logic 0 selects raw Vsync as the output
Vsync. Logic 1 selects sync separator output as the active Vsync. Note
that the indicated Vsync is used only if Bit 3 is set to Logic 1.
******0*
Bit 1—COAST Select. Logic 0 selects the COAST input pin used for the
PLL coast. Logic 1 selects Vsync to be used for the PLL coast.
*******1
Bit 0—PWRDN. Full Chip Power-Down, active low. Logic 0 = full chip
power-down; Logic 1 = normal.

Sync Separator
Threshold
Sync Separator Threshold. Sets the number of clock cycles that the sync
separator counts before toggling high or low. This should be set to a
number greater than the maximum Hsync or equalization pulse width.
