8 / 36 page  Feb./2005 8 TC90101FG 5. H/V Sync processing 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. [1] : Syncronized with input signal. 6. D2 signal (525p/525p component) processing 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 Noise level detection, (The sliced data of ID-1 can be read via IIC.) 7. T.O.F (Take Off filter) 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 [001] : type 1- [111] : type 7 (Type 1 : BPF.) 8. Y process a) Vertical enhancement : adjustable coring, gain, and non-linear performance b) LTI function The performance of this function is controlled via Iregisters at 04 and 05 hex. f0 : 3.3MHz / 2.2MHz Coring : 0.8IRE/1.6IRE/3.2IRE/6.4IRE Gain : Off / 1/8 / 1/4 / 1/2 c) Sharpness The performance of this function is controlled via Iregisters at 02 and 03 hex. f0 : 4.2MHz / 3.3MHz Coring : 0.8IRE/1.6IRE/3.2IRE/6.4IRE Gain : -1/4 - Off - 1/2 d) Noise canceller The performance of this function is controlled via Iregisters at 04 hex. f0 : 4.2MHz / 3.3MHz ( It uses same register with f0 of sharpness control.) Coring : 0.8IRE/1.6IRE/3.2IRE/6.4IRE Gain : -1/4 - Off - 1/2 e) Contrast Control range : ×(1/2) - ×2.4 f) Brightness it’s effective at the periode of picture signal portion. Control range : -128LSB - 128LSB ( 10bit unit) 9. C process 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. 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 d) Sub color gain control Amplitude of Cb and Cr signals are controlled via IIC. Control range is –6dB --- +2.8dB ｆ0/Gain/Coring LTI ＋ Sharpness/ Noise canceｌ ｆ0/Gain/Coring |
