d) Sub color gain control
a) ACC control : A reference level is set up by register ACC LEVEL.
b) Killer control : sensitivity of killer is set via [BUS KILLV] at sub address 37 hex.
c) HUE control : Hue control is available for CVBS and C signal of NTSC system.
5. H/V Sync processing
6. D2 signal (525p/525p component) processing
7. T.O.F (Take Off filter)
8. Y process
9. C process
TC90101FG has H/V sync separation circuit and regenrates HD/VD pulse.
The phase and width of HD/VD pulse are controled via THRHV at sub address 22hex.
[0] : 656 format.
TC90101FG has D1 and D2 detection circuit and Sync processing for D2 signal.
D2 signal is converted as 4:2:2 digital signal by internal ADC. (Sampling rate of Y ADC is 27MHz.)
ID-1 data slice for 525p is available but It’s not available to use picture implrovement function and
TC90101FG has Take Off filiter which is in front of color decoder.
Characteristic of T.O.F is set via TOF at sub address 0C hex.
[000] : Off
(Type 1 : BPF.)
a) Vertical enhancement : adjustable coring, gain, and non-linear performance
b) LTI function
c) Sharpness
d) Noise canceller
e) Contrast
[1] : Syncronized with input signal.
Noise level detection, (The sliced data of ID-1 can be read via IIC.)
f) Brightness
Amplitude of Cb and Cr signals are controlled via IIC.
Control range is –6dB --- +2.8dB
The performance of this function is controlled via Iregisters at 04 and 05 hex.
The performance of this function is controlled via Iregisters at 02 and 03 hex.
The performance of this function is controlled via Iregisters at 04 hex.
Control range : ×(1/2) - ×2.4
it’s effective at the periode of picture signal portion.
Control range : -128LSB - 128LSB ( 10bit unit)
Coring : 0.8IRE/1.6IRE/3.2IRE/6.4IRE
Coring : 0.8IRE/1.6IRE/3.2IRE/6.4IRE
Coring : 0.8IRE/1.6IRE/3.2IRE/6.4IRE
Gain : Off / 1/8 / 1/4 / 1/2
Gain : -1/4 - Off - 1/2
Gain : -1/4 - Off - 1/2
f0 : 3.3MHz / 2.2MHz
f0 : 4.2MHz / 3.3MHz
f0 : 4.2MHz / 3.3MHz ( It uses same register with f0 of sharpness control.)
In case Killer detection, comb filter for Y becomes off.
[001] : type 1- [111] : type 7
Hue range : -45 degree --- +43.6degree
Hue bias : 0 --- +45degree
