VENH2 to VENH0 : Set vertical enhancer gain.
000 : (+0.0) to 111 : (+1.5)
PDSOFF : Switches pedestal clip ON / OFF after vertical edge enhancement circuit.
0 : ON
1 : OFF
CB : Sets Color Killer mode to ON / OFF
0 : Y signal comb function ON
1 : Y signal comb function OFF (Same composite signal is output from Y and C pins.)
VNIR3 to VNIR0 : Set vertical enhancer non-linear point.
0000 : 4 LSB (internal set of IC to 4 LSB) to 1111 : 64 LSB (internal set of IC to 64 LSB)
GSEL1 : Sets Y output horizontal peaking gain.
0 : 1.5 dB
1 : 3.0 dB
GSEL0 : Switches Y output horizontal peaking ON / OFF.
0 : ON
1 : OFF
COR1 and COR0 : Set vertical enhancer coring level.
00 : 0 LSB to 11 : 3 LSB
TRAP : Sets C output 1 / 2 fsc trap ON / OFF.
0 : ON
1 : OFF
CHTRAP : Sets C output trap gain.
0 :
24 dB
1 :
16 dB
CBPF : Switches C output BPF ON / OFF (BPF characteristic after dynamic comb filter output).
0 : Narrow band
= BPF → ON
1 : Wide band
= BPF → OFF
ENHOFF : Sets KILLER pin function.
0 : Comb ON / OFF
1 : Comb ON / OFF and vertical edge enhancement ON / OFF
Signal level inside the IC
The sync tip of the input video signal is clamped to an internal level equivalent to 6 LSB. When a signal
amplitude of 1.0 V is equivalent to 140 IRE, 100% white status becomes an internal level of 209 LSB. At this
time, the input dynamic range of 256 LSB is equivalent to 1.3 Vp-p.
