RGB Coarse Clamp Control

Subaddress

2Fh

(Default 8Ch)

Reserved

RGB leakage [5:0]

RGB leakage [5:0]: RGB channel coarse clamp leakage current switch. Increasing the coarse clamp leakage current increases horizontal

droop but improves hum rejection.

00h = 0.5

μA

0Ch = 6.5

μA when IBIAS = 2 μA (default)

3Fh = 32.0

μA when IBIAS = 2 μA

Droop_Current = 0.5 + (IBIAS/4) × NDC, where 0 ≤ NDC ≤ 63

SOG Coarse Clamp Control

Subaddress

30h

(Default 04h)

Reserved

SOG leakage [5:0]

SOG leakage [5:0]: SOG coarse clamp leakage current switch. The SOG coarse clamp leakage current is derived from the bias current.

Increasing the coarse clamp leakage current increases horizontal droop but improves hum rejection.

00h = 0.01

μA

04h = 0.21

μA when IBIAS = 2 μA (default)

3Fh = 3.16

μA when IBIAS = 2 μA

Droop_Current = (0.01 + (IBIAS/40) × NDC, where 0 ≤ NDC ≤ 63

NOTE: IBIAS is controlled using Trim clamp [3:0] at subaddress 2Ch.

ALC Placement

Subaddress

31h

(Default 5Ah)

ALC placement [7:0]

ALC placement [7:0]: Positions the ALC signal an integer number of clock periods after either the leading edge or the trailing edge (default)

of the HSYNC signal. Bit 3 of subaddress 15h allows selecting which edge of HSYNC is used as the timing reference for ALC placement.

The ALC must be applied after the end of the fine clamp interval.

0 = Minimum setting

18h = PC graphics and SDTV with bi-level syncs

5Ah = HDTV with tri-level syncs (default)
