Gamma compensation and clamping operation are performed based on this level. Reference signal RGB signal input XCLP1 1.2µ 0.4µ 0.4µ XCLP2 Bright adjustment The position of the RGB signal relative to the reference level changes according to the voltage applied to RGB MBRT (Pin 1). Bright can be controlled without changing the γ characteristics to the panel because the input bias is changed with the breakpoint for output kept constant.

The black and white side gains and the black and white side gain change points can each be adjusted independently. Output Output Reference level Reference level Input Input Gain adjustment Breakpoint variation Sample-and-hold, gain control and pedestal clamp Since sample-and-hold circuits are established in the R, G and B lines and each of these circuits is operated by an independent pulse, the delay can be set freely. In addition, the pulse leak is canceled by establishing a sample-and-hold circuit in the clamp loop and inputting the differential input of the gain control circuit.

The relationship between input and output is as shown in the figure below. RGB IN FRP Signal center RGB OUT SID output The CXA1853Q outputs a side black signal for 4:3/16:9 aspect conversion. The black level is adjusted by the SID CTR pin. In addition, the PRG level can be set in part of the side black signal by inputting the PRG pulse. The PRG level is adjusted by the PRG CTR pin. The relationship between each input and output is as shown in the figure below. PRG SIDFRP Signal center SID OUT PRG level Signal center control The RGB and SID output center voltages are adjusted by the SIG CENT CTR (Pin 37). When SIG CENT CTR is preset, the output pin center voltage goes to VCC2/2. Output clamp The average value of each RGB and SID output signal is detected with external RC circuits and input to the RGB CLP and SID CLP pins. Then the center voltage offsets among R, G, B and SID outputs are reduced by feedback which equalizes these detected values and the signal center voltage set by the SIG CENT CTR pin. – 32 – CXA1853AQ Notes on Operation 1) R IN (Pin 9), G IN (Pin 10), B IN (Pin 11) input signal impedance An external capacitor is used as the hold capacitor for the clamp at the input of this IC. Therefore, the input signal impedance must be sufficiently low (75Ω or less) and the external capacitor must have a small leak current. 2) Clamp hold capacitors (Pins 51 to 53 and 65 to 67) The external capacitors connected to these pins must have a small leak current. 3) R, G, B, SID OUT load capacitance The output signal will tend to oscillate if the R, G, B and SID OUT load capacitance increases. Be sure to insert a 100 to 220Ω resistor in series to these output pins, and design to keep the load capacitance from exceeding 30pF. 4) External capacitor at the output The leak current absolute value and tolerance for the R, G, B and SID OUT average value detecting capacitors should be small. Note that if there is an offset in the leak current between R, G and B, offset voltage is also generated between R, G and B in the external resistor, which causes a DC offset of the output signal. R, G, B, SID OUT 100 to 220Ω Load capacitance 30pF or less 390kΩ R, G, B, SID CLP 1µF 5) GND and power supply pins Pins 12, 22, 34, 48, 55 and 64 (GND) should be set to the minimum identical potential applied to the IC, and should not be left open. In addition, the potential at Pins 8, 18, 50 and 62 should be the same. – 33 – CXA1853AQ Application Circuit CXD2412AQ Timing Generator 5V 0.01µ VR 100 100 100 100 VR VR 100 100 VR 100µ 0.1µ 0.1µ 0.1µ GCA DETG GCA DETR GCA DETB 33k RGB GAIN CAM SEL 42 WHT LIM 41 SIG SEL R GAIN B GAIN XCLP1 44 60 5V SH1 PVCC 0.01µ 100µ SH IN GND 0.1µ 0.1µ 0.1µ B CLAMP G CLAMP R CLAMP VR VR VR VR VR VR VR VR VR VR VR VR RGB GAM GAIN1 R GAM GAIN1 B GAM GAIN1 RGB GAM GAIN2 R GAM GAIN2 B GAM GAIN2 RGB GAM CTR2 R GAM CTR2 B GAM CTR2 RGB GAM CTR1 R GAM CTR1 B GAM CTR1 N.C. 61 62 63 64 65 66 67 68 69 70 GND 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 XCLP2 43 VCC4 IREF N.C.
