DIV2

Phase Select [4:0]: ADC sampling clock phase select. (1 LSB = 360/32 = 11.25°). A host-based automatic phase control algorithm can be

used to control this setting to optimize graphics sampling phase.

00h = 0 degrees

10h = 180 degrees (default)

1Fh = 348.75 degrees

DIV2: DATACLK divide-by-2. H-PLL post divider. May be used with a 2x H-PLL feedback divider to improve jitter at low frequencies. When

used, only half of the Phase Select [4:0] settings are functional.

0 = DATACLK/1 (default)

1 = DATACLK/2

Clamp Start [7:0]

Clamp Start [7:0]: Positions the clamp signal an integer number of clock periods after the HSYNC signal. If external clamping is selected

this value has no meaning. Clamp Start must be correctly positioned for proper operation. See Table 13 for the recommended settings.
