Preset Value
CVBS / Y GAIN
Switches output gain.
Gain of CVBS / Y / G OUT outputs (pins 2) is controlled.
00: 0dB
01: -3dB

+
3dB
11: Not available
Remark: GAIN = 01 (-3dB) is recommended for the 1125/50p/60p format since
this offers superior frequency characteristics to those of other modes.
CbCr GAIN
Switches output gain.
Gain of CbCr(B/R) OUT outputs (pins 4,6) is controlled.
00: 0dB
01: -3dB

1: Separated C and CVBS input t
(pin 58: Y, pin 56: C, pin 54: CVBS)
* If ”1: Separated C and CVBS input” is selected for CbCr PIN3, then CLAMP3
mode is set for “SYNC TIP CLAMP (for CVBS/Y) & SYNC TIP CLAMP (for
CVBS)”
Cb/Cr input
(0)
CLAMP1(3)
Switches Y1 (3)/G1(G3) & Cr1(3)/R1(3) clamping mode.
The clamping mode for pin 40(58) & pin 36(54) is set.
0: SYNC TIP CLAMP (for Y/G with sync) & BIAS (Cr/R )
1: BIAS (for RGB without sync)
* If ”1: Separated C and CVBS input” is selected for CbCr PIN1(3), then CLAMP
mode is set for “SYNC TIP CLAMP (for CVBS/Y) & SYNC TIP CLAMP (for
CVBS/Y)”
SYNC TIP
(0)
CLAMP2
Switches Y2 clamping mode.
The clamping mode for pin 52 is set.
0: SYNC TIP CLAMP (for Y/G with sync)
