ADV7183A
SDP COLOR CONTROLS
The following registers provide user control over the picture
appearance, including control of the active data in the event of
video being lost. They are independent of any other controls.
For instance, brightness control is independent from picture
clamping, although both controls affect the signal’s dc level.
Rev. A | Page 25 of 104
CON[7:0] Contrast Adjust (SDP), Address 0x08, [7:0]
This is the user control for contrast adjustment for the SDP
block only.
Table 44. CON Function
CON[7:0]
Description (Adjust Contrast of the Picture)
0x80*
Gain on luma channel = 1.
0x00
Gain on luma channel = 0.
0xFF
Gain on luma channel = 2.
*Default value.
SAT[7:0] Saturation Adjust (SDP), Address 0x09, [7:0]
The user can adjust the saturation of the color output using this
register. This registers affects the SDP core only.
ADI encourages users not to use the SAT[7:0] register, which
may be removed in future revisions of the ADV7183A. Instead,
the SD_SAT_Cb and SD_SAT_Cr registers should be used.
Table 45. SAT Function
SAT[7:0]
Description (Adjust Saturation of the Picture)
0x80*
Chroma gain = 0 dB.
0x00
Chroma gain = –42 dB.
0xFF
Chroma gain = 6 dB.
*Default value.
SD_SAT_Cb[7:0] SD Saturation Cb Channel (SDP),
Address 0xE3, [7:0]
This register allows the user to control the gain of the Cb
channel only.
For this register to be active , SAT[7:0] must be programmed
with its default value of 0x80. If SAT[7:0] is programmed with a
different value, SD_SAT_Cb[7:0] and SD_SAT_Cr[7:0] are
inactive.
Table 46. SD_SAT_Cb Function
Description
(Adjust Saturation of the Picture)
0x80*
Chroma gain = 0 dB.
0x00
0xFF
*Default value.
SD_SAT_Cb[7:0]
SD_SAT_Cr[7:0] SD Saturation Cr Channel (SDP),
Address 0xE4, [7:0]
This register allows the user to control the gain of the Cr
channel only. This register affects the SDP core only.
For this register to be active, SAT[7:0] must be programmed
with its default value of 0x80. If SAT[7:0] is programmed with a
different value, SD_SAT_Cb[7:0] and SD_SAT_Cr[7:0] are
inactive.
Table 47. SD_SAT_Cr Function
Description
(Adjust Saturation of the Picture)
0x80*
Chroma gain = 0 dB
0x00
0xFF
*Default value.
SD_SAT_Cr[7:0]
SD_OFF_Cb[7:0] SD Offset Cb Channel (SDP),
Address 0xE1, [7:0]
This register allows the user to select an offset for the Cb
channel only. This register affects the SDP core only. There is a
functional overlap with the Hue [7:0] register.
Table 48.SD_OFF_Cb Function
Description
(Adjust Hue of the Picture by Selecting an
Offset for Data on the Cb Channel)
0x80*
0x7F
0xFF
*Default value.
SD_OFF_Cb[7:0]
SD_OFF_Cr [7:0] SD Offset Cr Channel (SDP),
Address 0xE2, [7:0]
This register allows the user to select an offset for the Cr
channel only. This register affects the SDP core only. There is a
functional overlap with the Hue [7:0] register.
Table 49. SD_OFF_Cr Function
Description
(Adjust Hue of the Picture by Selecting an
Offset for Data on Cr Channel)
0x80*
0x7F
0xFF
*Default value.
SD_OFF_Cr[7:0]
