2.11.50 Back-End AGC Control Register

Functional Description

2.11.50 Back-End AGC Control Register

Subaddress		6Ch

Default		08h

7		6			5	4	3	2	1	0

			Reserved				1	Peak	Color	Sync

This register disables the back-end AGC when the front-end AGC uses specific amplitude references (sync-height, color burst, or composite peak) to decrement the front-end gain. For example, writing 0x09 to this register disables the back-end AGC whenever the front-end AGC uses the sync-height to decrement the front-end gain.

Peak: Disables back-end AGC when the front-end AGC uses the composite peak as an amplitude reference.

0 = Disabled (default)

1 = Enabled

Color: Disables back-end AGC when the front-end AGC uses color burst as an amplitude reference.

0 = Disabled (default)

1 = Enabled

Sync: Disables back-end AGC when the front-end AGC uses the sync height as an amplitude reference.

0 = Disabled (default)

1 = Enabled

2.11.51 AGC Decrement Speed Control Register

Subaddress		6Fh

Default		04h

7		6		5	4	3	2		1		0

				Reserved				AGC decrement speed [2:0]

AGC decrement speed: Adjusts gain decrement speed. Only used for composite/luma peaks.

111 = 7 (slowest)

110 = 6 (default)

L

000 = 0 (fastest)
