Function
TC90A67F has horizontal and vertical sync separation circuit for sub picture, color demodulation circuit for sub picture, horizontal and vertical timing generation circuit for main picture, PIP control circuit. Color demodulation circuit consists of digital circuit, and corresponds to M-NTSC, PAL, M-PAL, N-PAL system. It is possible to process the sub picture easily, according to adopting system clock of 24 MHz by digital PLL circuit locked fH. Horizontal and vertical timing generation circuit uses system clock (24 MHz) generated by analog PLL circuit locked main picture's fH. PIP control circuit consists of filter for horizontal and vertical reduction, line memory, field memory and according to changing horizontal and vertical reduction factors, it is possible to carry out various pip sizes.
1. ADC, Clamping Circuit
Dynamic range of ADC is 1.32 Vp-p whose voltage is fixed in IC. (top voltage is 2.31 V, bottom voltage is 0.99 V) ADC has pedestal clamp function, base voltage is output from CLMP terminal. The pedestal level becomes about 1.32 V. (64LSB)
2. Horizontal and Vertical Sync for Main Picture
It is necessary to input main picture's H-sync and V-sync at PHD and PVD terminal in order to make system clock for readout stored data into the internal field memory. PHD and PVD are fitted to 5 V. It can be inverted the polarity using IICBUS registers WHINV and WNINV at sub address 29hex. At terminals of IC, polarity of H-sync is positive and V-sync is negative. The clocks from external VCO are selectable in 24 MHz and 48 MHz, it can be switched by given voltage to CKPSEL (SDIP: 52 pin, QFP: 57 pin) terminal. (CKPSEL = L: 24 MHz, CKPSEL = H: 48 MHz)
3. The System Clock Locked to the Sub Picture's Horizontal Sync.
The signal converted into the digital environment passes through horizontal sync separation circuit, horizontal locked circuit, which construct PLL circuit, it makes the system clock locked to the sub picture's horizontal sync. This clock is put in internal VCO and generated the system clock of 24 MHz.
4. Horizontal Reduction
It is necessary to limit to frequency bandwidth for Y signal and color difference signal concerning PIP mode. Horizontal reduction is selectable using HWS. (HWS: sub address 10hex)
HWS [1:0] 00 01 10 11
Horizontal Reduction 1/3 1/4 1/6 1/8
Sampling Rate for Y 4 MHz 3 MHz 2 MHz 1.5 MHz
Sampling Rate for Color Difference 1 MHz 0.75 MHz 0.5 MHz 0.375 MHz
In order to horizontal reduction, LPFs are used for Y signal and color difference signal. It is selectable in two kinds of LPF for Y signal and six kinds of LPF for color difference signal.

5. Vertical Reduction
It is necessary to reduce vertical direction concerning PIP mode, and vertical reduction is carried out from multiplication of coefficient as below. Vertical reduction is selectable using VWS. (VWS: sub address 10hex)

Vertical Reduction 1/3 (VWS [1:0] = 00) 1/4 (VWS [1:0] = 01) 1/5 (VWS [1:0] = 10) 1/6 (VWS [1:0] = 11)
6. The Sub Picture's Area of Writing in the Field Memory and Reading from the Field Memory
Writing start position is defined horizontal start point to write (sub address 16hex: CHS) and vertical start point to write. (sub address 16hex: CVSN or sub address 17hex: CVSP) CVSN: Vertical frequency of sub picture is 60 Hz CVSP: Vertical frequency of sub picture is 50 Hz Horizontal width of the sub picture is defined by sampling number of horizontal direction. (sub address 1Ahex: HSPL) The number of writing vertical lines is determined internally according to vertical frequency of the main picture and VWS. Reading start position is defined horizontal start point to read (sub address 14hex: PHS) and vertical start point to read. (sub address 14hex: PVSN or 15hex: PVSP) PVSN: Vertical frequency of sub picture is 60 Hz PVSP: Vertical frequency of sub picture is 50 Hz Horizontal display size of the sub picture is defined by PHW (sub address 12hex) and the readout number of vertical lines is defined by PVWN (sub address 12hex) or PVWP (sub address 13hex). PVWN: Vertical frequency of sub picture is 60 Hz PVWP: Vertical frequency of sub picture is 50 Hz
7. DACs for Y Signal and Color Difference Signal
TC90A67F is built-in three 8 bit-DAC in motion on 24 MHz. Output dynamic range is determined by the difference between VDD and VREFD terminal voltage. Standard level is 1.5 Vp-p.
8. ACC Control
ACC control is carried out comparing demodulation result of color burst signal with set reference level by ACCPAL or ACCNTSC register. (ACCPAL, ACCNTSC: sub address 21hex) When compared value is less than the reference level, controller puts on gain, and more than reference level, controller cuts down one.
9. Peaking Circuit for Y Signal
It is possible to carry out a clear picture according to putting up some frequency bandwidth when sub picture becomes indistinct picture for reducing high frequency bandwidth using LPF for Y signal. There are two kinds of characteristics for LPF, and it is selectable about gain of four stages respectively using YPKGS and YPKGG. YPKGS: select for LPF characteristics (sub address 10hex) YPKGG: select for gain (sub address 10hex)
10. PGB Matrix Circuit
For a built-in RGB matrix circuit, and when RGBON = 1, it can be changed R-Y, Y, B-Y into RGB signal. How to find the value of coefficient (a, b, c) is as below. < 1Chex: MTXCR: a, MTXCG2: b, MTXCG1: c (on condition 0 < a < 1, 0 < b < 1, 0 = c < 1) = = R = a (R - Y) + Y G = b {-(R - Y)} + c {-(B - Y)} + Y B = (B - Y) + Y

11. Blue Back Function
It is possible to control blue back function using BBACK resister. (BBACK: sub address 13hex, BBACK = 1: blue back mode) It is available for only sub picture set to live mode. BBACK is useful when detected V chip or no signal. it can be selected in four kinds of colors using BLEVEL. (BLEVEL: sub address 13hex)
12. Addition of Frame
It is possible to add the frame to the sub picture. It is selectable frame width by FRAMEW and adjustable frame color for RGB or R-Y, Y, B-Y respectively by FRAMEYG, FRAMER, FRAMEB. (FRAMEW, FRAMEYG, FRAMER, FRAMEB: sub address 1Ehex)
