ADV7183B
Rev. B | Page 32 of 100
For example, program the ADV7183B into manual fixed gain
mode with a desired gain of 0.89.
1.
Use Equation 1 to convert the gain:
0.89 × 2048 = 1822.72
2.
Truncate to integer value:
1822.72 = 1822
3.
Convert to hexadecimal:
1822d = 0x71E
4.
Split into two registers and program:
Luma Gain Control 1[3:0] = 0x7
Luma Gain Control 2[7:0] = 0x1E
5.
Enable manual fixed gain mode:
Set LAGC[2:0] to 000
BETACAM Enable Betacam Levels, Address 0x01[5]
If YPrPb data is routed through the ADV7183B, the automatic
gain control modes can target different video input levels, as
outlined in
192H
Figure 40. The BETACAM bit is valid only if the
input mode is YPrPb (component). The BETACAM bit sets the
target value for AGC operation.
A review of the following sections is useful:
193H
INSEL[3:0] Input Selection, Address 0x00[3:0] to find how
component video (YPrPb) can be routed through the
ADV7183B.
194H
Video Standard Selection to select the various standards,
such as those with and without pedestal.
The automatic gain control (AGC) algorithms adjust the levels
based on the setting of the BETACAM bit (see
195H
Table 37).

Selecting PAL without pedestal selects SMPTE
Selecting NTSC with pedestal selects MII
Selecting NTSC without pedestal selects SMPTE

PW_UPD Peak White Update, Address 0x2B[0]
The peak white and average video algorithms determine the
gain based on measurements taken from the active video. The
PW_UPD bit determines the rate of gain change. The
LAGC[2:0] must be set to the appropriate mode to enable the
peak white or average video mode in the first place. For more
information, refer to the
196H
LAGC[2:0] Luma Automatic Gain
Control,
Address 0x2C[7:0] section.
Setting PW_UPD to 0 updates the gain once per video line.
Setting PW_UPD to 1 (default) updates the gain once per field.
Chroma Gain
CAGC[1:0] Chroma Automatic Gain Control,
Address 0x2C[1:0]
The two bits of the Color Automatic Gain Control mode select
the basic mode of operation for automatic gain control in the
chroma path.
Table 38. CAGC Function
CAGC[1:0]
Description
00
Manual fixed gain (use CMG[11:0])
01
Use luma gain for chroma
10 (default)
Automatic gain (based on color burst)
11
Freeze chroma gain
CAGT[1:0] Chroma Automatic Gain Timing,
Address 0x2D[7:6]
The chroma automatic gain timing register allows the user to
influence the tracking speed of the chroma automatic gain con-
trol. This register has an effect only if the CAGC[1:0] register is
set to 10 (automatic gain).
