TC90A92AFG
(7) Take off filter (TOF)
TC90A92AFG has a take off filter in front of internal color decoder.
Characteristic of TOF is set via [TOF] at sub address 0F hex.
000 : OFF
001 : BPF for cross color reduction is active.
010 –111Ftype2 – type7
(8) Y process
a) Vertical enhance : available to set coring, gain and non-linear performance
b) LTI function
f0 is selectable (3.3MHz/ 2.2MHz).
Coring level is selectable (0.8IRE/ 1.6IRE/ 3.2IRE/ 6.4IRE).
Gain is selectable (OFF/ x1/8 / x1/4 / x1/2).
c) Sharpness
f0 is selectable (4.2MHz/ 3.3MHz).
Coring level is selectable (0.8IRE/ 1.6IRE/ 3.2IRE/ 6.4IRE).
Gain is selectable (OFF/ x1/8 / x1/4 / x1/2).
d) Noise chancellor
f0 is 4.2MHz.
Gain is selectable (OFF/ x1/4 / x1/2 / x1).
Coring level is selectable (0.8IRE/ 1.6IRE/ 3.2IRE/ 6.4IRE).
e) Contrast
Control range is –6dB --- +7.6dB
(The color becomes a saturation depending on input level.)
f) Brightness control
Control range is 0LSB ---+ 60LSB (10bit unit)
Brightness control is effective at the period of picture area.
(9) C process
a) ACC control : A reference level is set up by register ACC LEVEL. (Recommended value is under 3)
b) Killer control : sensitivity of killer is set via [COLOR KILL LEVEL] at sub address 0E hex.
In case Killer detection, comb filter for Y becomes off.
c) HUE control : Hue control is available for CVBS and C signal of NTSC system.
Hue bias : 0 --- +45degree
Hue range : -45 degree --- +43.6degree
Base band Tint control is available for component signal input mode.
Hue range : -45 degree --- +43.6degree
