(During internal sync separation signal input) During RGB input: The G signal is input to Pins 71 and 69, the B signal to Pin 70, and the R signal to Pin 72. During Y/color difference input: The Y signal is input to Pins 71 and 69, the B-Y signal to Pin 70, and the R-Y signal to Pin 72. (During external sync signal input) During RGB input: The G signal is input to Pin 71, the B signal to Pin 70, the R signal to Pin 72, CSYNC/HD to Pin 5, and VD to Pin 10. During Y/color difference input: The Y signal is input to Pin 71, the B-Y signal to Pin 70, the R-Y signal to Pin 72, CSYNC/HD to Pin 5, and VD to Pin 10. • NTSC/PAL switching The input system (NTSC/PAL) can be switched by the serial communication settings. • Picture circuit This performs aperture correction for the Y signal. The center frequency to be corrected and the correction amount are controlled by serial communication. In addition, when not using the picture circuit, it can be turned off by serial communication. • Hue circuit This is the hue adjustment circuit for the color difference signal. It is controlled by serial communication. • Matrix circuit This circuit converts Y, R-Y and B-Y signals into RGB signals. • LPF circuit This is the band limitation filter for the RGB signal. It is used to eliminate the noise component generated at the front end of this IC. The cut-off frequency can be controlled by serial communication. In addition, when not using the LPF, it can be turned off by serial communication. • Trap circuit This is used to eliminate the DSP clock and RGB decoder carrier leak generated at the front end of this IC. The center frequency can be switched between 13.5MHz and 14.3MHz by serial communication. In addition, when not using the trap, it can be turned off by serial communication. • Contrast adjustment circuit This adjusts the white-black amplitude to set the input RGB signal to the appropriate output level. • OSD This inputs the OSD pulses. There are two input threshold values: Vth1 (VCC1 × 1/3) and Vth2 (VCC1 × 2/3). When an input exceeds Vth1, the corresponding output falls to the level specified by BLACK-LIMITER. When an input exceeds Vth2, the corresponding output rises to the level specified by WHITE-LIMITER. Also, when one of the RGB inputs exceeds Vth1, any signal outputs not exceeding Vth1 also fall to the level specified by BLACK-LIMITER. – 23 – CXA3522R • Sample-and-hold circuit This circuit performs time axis correction for the RGB output signals in order to support the RGB simultaneous sampling systems of LCD panels.

Since LCD panels perform color coding using an RGB delta arrangement, each horizontal line must be compensated by 1.5 dots. This relationship is reversed during right/left inversion. This compensation and other timing is also generated by the digital block. The sample-and-hold timing changes according to the phase relationship with the HCK pulse, so the timing should be set to the SHS1 to SHS6 position in accordance with the actual board. • γ correction In order to support the characteristics of LCD panels, the I/O characteristics are as shown in Fig. 1. The γ1 gain transition point A voltage changes as shown in Fig. 2 by adjusting the serial bus register γ1, and the γ2 gain transition point B voltage changes as shown in Fig. 3 by adjusting γ2. Output Output Output B' A' B' B A A B Input Fig. 1 A B Input Fig. 2 – 24 – Input Fig. 3 CXA3522R • Bright circuit This is used to adjust the black-black amplitude of polarity-inverted RGB output signals. It is not interlinked with the γ transition points. • White balance adjustment circuit This is used to adjust the white balance. The black level is adjusted by SUB-BRIGHT, and the black-white amplitude is adjusted by SUB-CONTRAST. • Output circuit RGB output (Pins 70, 71, and 72) signals are inverted each horizontal line by the FRP pulse (internal pulse) supplied from the TG block as shown in the figure below. Feedback is applied so that the center voltage (SIG.C) of the output signal matches the reference voltage (VCC2 + GND2)/2 (or the voltage input to SIG.C (Pin 30)). In addition, the white level output is clipped at the limiter operation point that is set by the serial communication WHITE-LIMITER, and the black level output is clipped at the limiter operation point that is set by the serial communication BLACK-LIMITER. The output PSIG signal level is normally adjusted by PSIG-BRIGHT, but during black frame display the level is specified by BLACK-LIMITER during V blanking. In addition, the RGB output also simultaneously goes to BLACK-LIMITER level output.

The voltage is offset by serial communication using the SIG.C voltage as the reference and then output. 3) DAC output circuit There are two DAC output circuit systems. The DA OUT output circuit outputs DC 3.0V at equal divisions. The REF output circuit generates and supplies the REF voltage for the panel level shifter circuit to the LCD panel. Both circuits are controlled by serial communication. 4) Sync system • H FIL This amplifies the sync signal of the input video signal and eliminates the noise with an internal LPF. The sync signal is clamped at the input, so be sure to input via a capacitor. • SYNC SEP This inputs the FIL OUT (Pin 2) output and performs sync separation. The signal is output from SYNC OUT (Pin 4) as a positive polarity pulse. 5) Power saving circuit (PS circuit) A power saving system can be realized together with the LCD panel by independently controlling (serial communication) the operation of each output block. This system is also effective for improving picture quality during power-on/off. The serial data PS0, PS1, PS2, PS4 and SYNC GEN must be set in order to use this IC. For details of the setting methods, see the "Description of Serial Control Operation" and "Power Supply and Power Saving Sequence" items. – 26 – CXA3522R 6) TG block • PLL and AFC circuits A PLL circuit can be comprised by connecting a PLL circuit phase comparator and frequency division counter and external VCO and LPF circuits. The PLL error detection signal is generated using the phase comparison output of the entire bottom of the horizontal sync signal and the internal frequency division counter as the RPD output. RPD output is converted to DC error voltage with the lag-lead filter, and then it changes the capacitance of the varicap diode to stabilize the oscillation frequency. The PLL of this system is adjusted by setting the reverse bias voltage of the varicap diode so that the point at which RPD changes is at the center of the horizontal sync signal window as shown in the figure below. Horizontal sync signal WS WS RPD (Pin 24) WL WH WL WH WL = WH • H-Position This adjusts the horizontal display position. Set this function so that the picture center matches the center of the LCD panel. • Right/left (RGT) and/or up/down inversion (DWN) The video display direction can be switched. The horizontal direction can be switched between right scan and left scan, and the vertical direction between down scan and up scan. Set the display direction in accordance with the LCD panel mounting position. • Overscan display mode Displaying black in the up/down 6 lines and right/left 18 (19) dots of the display area generates overscan area (black frame) in the display area. 453 DOTS Black display 490 DOTS 6 LINES 240 LINES Display area Display area 228 LINES 6 LINES Normal display Black frame display • AC driving of LCD panels during no signal The output signal runs freely so that the LCD panel is AC driven even when there is no sync signal from the FIL IN (Pin 69) pin or from the CSYNC/HD (Pin 5) and VD (Pin 10) pins. It also runs freely when there is no sync signal during 281H (NTSC) and 331H (PAL) of display system. Respective cycles are 281H (NTSC) and 331H (PAL). – 27 – CXA3522R Description of Serial Control Operation 1) Control method Control data consists of 16 bits of data which is loaded one bit at a time at the rising edge of SCK. This loading operation starts from the falling edge of SEN and is completed at the next rising edge. Digital block control data is established by the vertical sync signal, so if data is transferred multiple times for the same item, the data immediately before the vertical sync signal is valid. Analog (electronic attenuator) block control data becomes valid each time the SEN signal is input. In addition, if 16 bits or more of SCK are not input while SEN is low, the transferred data is not loaded to the inside of the IC and is ignored. If 16 bits or more of SCK are input, the 16 bits of data before the rising edge of the SEN pulse are valid data.

The power supplies should also use a plain pattern. • Use ceramic capacitors for the by-pass capacitors between the power supplies and GND, and connect these capacitors as close to the pins as possible. • The resistor connected to Pin 8 should be connected as close to the pin as possible, and the wiring from the pin to GND should be as short as possible. Also, do not pass other signal lines close to this pin or the connected resistor. • The resistor connected to Pin 17 should be located as close to the pin as possible. Also, do not pass other signal lines close to this pin. • The capacitors connected to Pins 7 and 42 should be located as close to the LCD panel as possible. • The PLL block (LPF/VCO) should be compact and located near the IC. (2) The R/R-Y (Pin 72), G/Y (Pin 71), B/B-Y (Pin 70) and FIL IN (Pin 69) pin input signals are clamped at the inputs using the capacitors connected to each pin, so these signals should be input at sufficiently low impedance. (Input at an impedance of 1kΩ (max.) or less.) (3) The smoothing capacitor of the DC level control feedback circuit in the capacitor block connected to the RGB output pins should have a leak current with a small absolute value and variance. Also, when using the pulse elimination (PAL display, WIDE display) function, the picture quality should be thoroughly evaluated before deciding the capacitance value of the capacitor. (4) A thorough study of whether the capacitor connected to the COM output pin satisfies the LCD panel specifications should be made before deciding the capacitance value. (5) If this IC is used in connection with a circuit other than an LCD, it may cause that circuit to malfunction depending on the order in which power is supplied to the circuits. Thoroughly study the consequences of using this IC with other circuits before deciding on its use. (6) Since this IC utilizes a C-MOS structure, it may latch up due to excessive noise or power surge greater than the maximum rating of the I/O pins, or due to interface with the power supply of another circuit, or due to the order in which power is supplied to circuits. Be sure to take measures against the possibility of latch up. (7) Be sure to observe the power supply and power saving sequence specifications specified for this IC. (8) Do not apply a voltage higher than VDD or lower than VSS to I/O pins. (9) Do not use this IC under operating conditions other than those given. (10) Absolute maximum rating values should not be exceeded even momentarily. Exceeding ratings may damage the device, leading to eventual breakdown. (11) This IC has a MOS structure which is easily damaged by static electricity, so thorough measures should be taken to prevent electrostatic discharge. (12) Always connect the VSS, GND1, GND2 and GND3 pins to the lowest potential applied to this IC; do not leave these pins open. The voltages applied to the power supply pins should be as follows. VSS = GND1 = GND2 = GND3 ≤ VDD = VCC1 ≤ VCC2 = VCC3. – 40 – CXA3522R Package Outline Unit: mm 72PIN LQFP (PLASTIC) 12.0 ± 0.3 14.5 ± 0.2 10.0 ± 0.2 0.65 ± 0.2 54 39 38 72 19 11.0 ± 0.2 55 1 0.5 18 0.2 ± 0.08 0.08 M A 0.15 ± 0.05 0.1 0.1 ± 0.1 0° to 10° DETAIL A PACKAGE STRUCTURE SONY CODE LQFP-72P-L111 EIAJ CODE P-LQFP72-10X10-0.5 PACKAGE MATERIAL EPOXY RESIN LEAD TREATMENT SOLDER PLATING LEAD MATERIAL 42 ALLOY PACKAGE MASS 0.3g JEDEC CODE – 41 – Sony Corporation
