SOG LPF SEL [1:0]: SOG low-pass filter selection. The SOG low-pass filter can be used to attenuate glitches present on

the SOG input. Excessive filtering can lead to sync detection issues and increased sample clock jitter.

00 = 2.5-MHz low-pass filter

01 = 10-MHz low-pass filter

10 = 33-MHz low-pass filter

11 = Low-pass filter bypass (default)

CLP LPF SEL [1:0]: Coarse clamp low-pass filter selection. This filter effects the operation of all enabled coarse clamps which is generally

the SOG coarse clamp only.

00 = 4.8-MHz low-pass filter (default). Suitable for HDTV and graphics formats.

01 = 0.5-MHz low-pass filter. Suitable for SDTV formats.

10 = 1.7-MHz low-pass filter

11 = Reserved

CLK SEL: Clock reference select for Sync Processing block. The internal reference clock is typically 6.5 MHz, but it should not be

interface, Sync Separator, and activity detection circuitry always uses the internal clock reference.

0 = Internal clock reference (default)

1 = External clock reference (EXT_CLK)

NOTE: The external clock input can also be selected as the sample clock for the ADCs (see bit 1).

VS SEL: VSYNC input select

0 = VSYNC_A input selected (default)

1 = VSYNC_B input selected

PCLK SEL: Pixel clock selection. When the external clock input (pin 80) is selected as the ADC sample clock, the external clamp pulse

(pin 76) should also be selected (Bit 7 of subaddress 0Fh).

0 = ADC samples data using external clock input (pin 80)

1 = ADC samples data using H-PLL generated clock (default)

NOTE: The external clock input can also be selected as the reference clock for the Sync Processing block (see bit 3).

HS SEL: HSYNC input select

0 = HSYNC_A input selected (default)

1 = HSYNC_B input selected

NOTE: See the Sync Control register at subaddress 0Eh.
