3.22.15 Luminance Processing Control #3 Register

Address 0Eh

7 6 5 4 3 2 1 0

Reserved Luminance trap filter select

Luminance filter stop band bandwidth (MHz):

00 = No notch (default)

01 = Notch 1

10 = Notch 2

11 = Notch 3

Luminance filter select [1:0] selects one of the four chroma trap filters to produce luminance signal by removing

the chrominance signal from the composite video signal. The stopband of the chroma trap filter is centered

at the chroma subcarrier frequency with stopband bandwidth controlled by the two control bits. Please refer

to Figure 3−5, for the frequency responses of the filters.

3.22.16 Configuration Shared Pins

Address 0Fh

7 6 5 4 3 2 1 0

Reserved LOCK23 LOCK24A LOCK24B FID/GLCO VSYNC/PALI INTREQ/GPCL/VBLK SCLK/PCLK

LOCK23 (pin 23) function select:

0 = FID (default, if bit 3 is selected to output FID)

1 = Lock indicator (Indicates whether device is locked both horizontally and vertically)

LOCK24A (pin 24) function select:

0 = VSYNC (default, if bit 2 is selected to output VSYNC)

1 = Lock indicator (Indicates whether device is locked both horizontally and vertically)

LOCK24B (pin 24) function select:

0 = PALI (default, if bit 2 is selected to output PALI)

1 = Lock indicator (Indicates whether device is locked both horizontally and vertically)

FID/GLCO (pin 23) function select (also refer to register 03h for enhanced functionality):

0 = FID

1 = GLCO (default)

VSYNC/PALI (pin 24) function select (also refer to register 03h for enhanced functionality):

0 = VSYNC (default)

1 = PALI

INTREQ/GPCL/VBLK (pin 27) function select:

0 = INTREQ (default)

1 = GPCL or VBLK depending on bit 7 of register 03h

SCLK/PCLK (pin 9) function select:

0 = SCLK (default)

1 = PCLK (1x pixel clock frequency)
