The initialization of the internal circuit should be also performed by maintaining the system clear pin at low during the specified time after setting the supply voltage in the range of recommended operating conditions and stabilizing as shown in the figure below. Keep in mind that the internal circuit may not be initialized correctly if system clear cancellation is performed before the supply voltage is set in the range of the recommended operating conditions. VDD1, VDD2 VDD1, VDD2 VSS VDD2 XCLR1, XCLR2, XCLR3 VSS TR TR > 200ns – 13 – CXD3511Q Description of Operation 1. Description of Input Pins (a) System clear pins (XCLR1, XCLR2 and XCLR3) All internal circuits are initialized by setting XCLR1 (Pin 27) low. In addition, the internal PLL is initialized by setting XCLR2 (Pin 28) low, and RGB output is initialized (preset) by setting XCLR3 (Pin 29) low. Initialization should be performed when power is turned on. There are no particular restrictions on the initialization order. (b) Sync signal input pins (HDIN and VDIN) Horizontal and vertical separate sync signals are input to HDIN (Pin 31) and VDIN (Pin 32), respectively. The CXD3511Q supports only non-interlace sync signals with a dot clock of 200MHz or less. (c) Master clock input pins (CLKP/CLKN and CLKC) Phase comparison is performed by an external circuit and a clock synchronized to the sync signal is input. The master clock input pins have two systems consisting of CLKP/CLKN (Pins 38 and 39) for small-amplitude differential input (center level: 2.0V, amplitude: ±0.4V), and CLKC (Pin 35) for CMOS level input. In addition, be sure to make the number of dot clocks in 1H as even number. Note that if there is an odd number of dot clocks, the internal phase compensation PLL will not operate properly. (d) Clock selection pins (CLKSEL1 and CLKSEL2) The master clock input pins can input either the system dot clock or the 1/2 frequency-divided clock. The internal clock path is selected according to CLKSEL1 (Pin 41) and CLKSEL2 (Pin 44).

The half-tone processing setting is as follows. YM signal input: 1 = Half tone processing ON, 0 = OFF Here, the video signal level is halved by shifting the input data by one bit to the LSB side when YM = 1. For example, when 0F0h is input, 078h is output. The selector selects one of four types of data with respect to the OSD signal value as shown in the table below. The selected data becomes the OSD signal scale data. The selected scale data can be set independently in 10 bits for R, G and B, so 4 scales can be selected as desired from among 1024 scales for each of R, G and B. Therefore, the desired 64 (= 2^6) colors can be selected from among the total 1.07374 billion (= 2^30) colors for R, G and B. OSD signal input Selected scale data 0h R, G, B_OSD_DAT1 1h R, G, B_OSD_DAT2 2h R, G, B_OSD_DAT3 3h R, G, B_OSD_DAT4 The OSD-MIX processing setting is as follows.

GAM_ON: 1 = Normal operation, 0 = Standby mode GAM_SEL: 1 = Path passing through the RAM, 0 = Path not passing through the RAM (All settings shared by R, G and B) When operating the RAM, be sure to set GAM_ON = 1. Data cannot be written to or read from the RAM in standby mode. The RAM data is set through the parallel I/F block. Note that the RAM output is undetermined while data is being set in this RAM, and also during power-on. RAM ON/OFF (GAM_ON) Select signal (GAM_SEL) Input 10 RAM 10 bits × 1024 words 10 – 33 – Selector 10 Output CXD3511Q (m) Color shading correction block This block corrects color shading by adding a correction signal to the video signal. Correction points are set at fixed intervals in the horizontal, vertical and scale directions of the video signal. The correction data for these correction points is written in the RAM, and a smooth correction curve is created by reading this data and performing interpolation operations. The settings are as follows. CSC_ON: 1 = Color shading correction processing ON, 0 = processing OFF CSC_H_MODE: Sets the horizontal correction interval to 32, 64 or 128 dots CSC_V_MODE: Sets the vertical correction interval to 32, 64 or 128 lines CSC_G_MODE: 1 = Scale correction processing ON, 0 = processing OFF CSC_HNUM: Sets the number of horizontal correction points CSC_VNUM: Sets the number of vertical correction points CSC_HP: Sets the horizontal correction start position in 2-dot units CSC_VP: Sets the vertical correction start position in 1-line units CSC_R (G, B)_RGT: 1 = Reflects the TG block RGT setting, 0 = Reflects the inverse of the TG block RGT setting CSC_DWN: 1 = Reflects the TG block DWN setting, 0 = Reflects the inverse of the TG block DWN setting CSC_XH_ON: 1 = Cross hatch insertion ON, 0 = OFF (All settings except CSC_R (G, B)_RGT shared by R, G and B) The RAM size is 8 bits × 520 words, so up to 520 correction points can be set. The correction data is set as 8-bit data with code. Correction data can be set in the range of –128 to +127 scale. The example shown in the figure below is for a 1024-dot × 768-line XGA video signal divided into 9 points at 128-dot intervals in the horizontal direction and 7 points at 128-line intervals in the vertical direction. The relationship between the correction point coordinates (m, n) and the RAM address is obtained as follows. RAM address = (m – 1) + (n – 1) × (Number of horizontal correction points) For the example in the figure below, this is as follows. (9 – 1) + (7 – 1) × 9 = 62 Thus, the correction data must be set in the RAM from address 0 to address 62. Up/down and/or right/left inversion of the LCD panel is supported by controlling the method of reading the correction data set in the RAM. Up/down and/or right/left inversion are set from DWN and RGT of the TG block. CSC_DWN and CSC_R (G, B)_RGT control the linking with the TG block settings. 1 1 2 3 4 5 6 7 8 9 2 (m, n) 4 768 lines 3 Color shading correction range 5 128 lines Vertical correction start position Horizontal correction start position 6 128 dots 7 1024 dots – 34 – CXD3511Q Interpolation operations in the horizontal and vertical directions are performed using the 16 points of correction data ( marks in the figure below) around the pixel to be corrected. First, interpolation operations are performed in the vertical direction using two upper and lower points of correction data at a time to obtain four data (× marks in the figure below). Next, interpolation operations are performed in the horizontal direction using these data to obtain the final correction data ( mark in the figure below). 1 1 2 3 4 5 6 7 8 9 2 3 4 5 6 7 : Correction data set in the RAM : Vertical interpolation operation results : Horizontal interpolation operation result Interpolation operations in the scale direction are performed using the correction data in the five RAMs. When CSC_G_MODE = 1, interpolation operations are performed in the scale direction. There are 5 correction points in the scale direction. The data set in RAM1 to RAM5 is treated as each scale level correction data as shown in the table below, and interpolation operations are performed in the horizontal and vertical directions for each RAM. Then the four operation results ( mark in the figure above) for that same pixel (coordinates) are selected according to the scale level of the video signal input to the color shading correction block, and interpolation operations are performed in the scale direction. Thus, when interpolation operations are performed in the scale direction, the correction data for each pixel is obtained from a total 64 points of correction data. When CSC_G_MODE = 0, correction operations are not performed in the scale direction, and the correction data calculated using the data set in RAM1 is reflected to all scales. The calculated correction data is added to the video signal. If these operation results overflow or underflow, clipping is performed and 3FFh or 000h is output.

When CSC_XH_ON = 1, the cross hatch is inserted. The cross hatch level is 3FFh. When CSC_XH_ON = 0, the cross hatch is not inserted. The color shading correction block RAM output is undetermined during power-on. When performing color shading correction, be sure to set data in these RAMs. When performing color shading correction in only the horizontal and vertical directions, be sure to set CSC_ON = 1 before setting data in RAM1 of each color. When performing color shading correction in the scale direction in addition to the horizontal and vertical directions, set CSC_ON = 1 and CSC_G_MODE = 1 before setting data in RAM1 to RAM5 of each color. When CSC_ON = 0 and CSC_G_MODE = 0, the RAMs are in standby mode and data cannot be set.

This block is comprised of five selectors: dot shift selector, right/left inversion selector, dot/line selector, up/ down inversion pre-selector, and up/down inversion post-selector. The delay line size is 1200 words. The data paths for this block are shown in the figure below. Port switching during right/left inversion depends on the Cond1 value, and port switching during up/down inversion (when dot/line inversion support is ON) depends on the Cond2 value.

Timing Generator (TG) Block This block generates the timing pulses required to drive Sony LCD panels. Of the output pulses, the required pulses differ according to the LCD panel type, so be sure to also check the specifications of the panel used. The output timing pulses are all set by the parallel I/F. For a detailed description, see the description of the parallel I/F TG block. The TG block diagram is shown below.

Parallel I/F Block Register data settings in this IC are performed by parallel data. As shown in the Timing Chart below, the parallel I/F comprises a total 12-bit wide bus consisting of control signal PCTL (Pin 12), clock signal PCLK (Pin 13) and 10-bit wide data signal PDAT[9:0] (Pins 14 to 17, 20 to 24 and 26). The data signal is input in the order of main address, sub address and data. When setting data in this IC, divide the data into 22 blocks as shown in the table on the next page. Next, the sub address specifies the initial address of the data to be written in the block designated by the main address. The data is set sequentially from the data at the address designated by the sub address. The address of each data set thereafter is automatically incremented by +1 from the address designated by the sub address, so further address setting is unnecessary. This makes it possible to set only the necessary data from the desired address of the desired block.

(a) Clock settings (1) CLKPOL (sub address: 000h) This sets the internal clock polarity. Setting value: 1 = Inverted, 0 = Not inverted The clock flow from the clock input pins to the PLL block is shown below. CLKP 1/2 CLKN To PLL Block CLKC CLKSEL1 CLKSEL2 CLKPOL (2) CLKOUT (sub address: 02Ch) This sets the Pin 47 clock output limit. Setting value: 1 = Inverted clock is output, 0 = Low is output (b) SYNC polarity settings (1) POLDET (sub address: 000h) This sets the sync polarity auto discrimination function ON/OFF. Setting value: 1 = Auto discrimination function ON, 0 = Auto discrimination function OFF When POLDET = 1, the HPOL and VPOL settings below are invalid. When using this function, the HDIN sync portion must be 1/2 or less of 1H, and the VDIN sync portion must come before the rise position of the VSTL/ R pulse. HDIN (Negative) N/2 or less N VDIN (Negative) Must come before VSTL/R VSTL/R (2) HPOL and VPOL (sub address: 001h) These set the sync signal polarity when POLDET = 0. Setting value: 1 = Positive polarity, 0 = Negative polarity The internal operation of this IC is with the input sync signal fixed to positive polarity. Therefore, these HPOL and VPOL must be set in accordance with the polarity of the sync signal input from HDIN and VDIN. Set HPOL and VPOL to "1" when the input sync signal is positive polarity, or to "0" when negative polarity. – 48 – CXD3511Q (c) Dots per 1H and lines per 1F settings (1) HR (sub address: 000h) This sets the PLL counter reset ON/OFF. Setting value: 1 = Reset enabled, 0 = Reset disabled When HR = 0, the internal frequency divider is used, and the HD1 pulse output should be used as the return pulse. The number of dot clocks per 1H is set by PLLP[11:1] below. (2) PLLP[11:1] (sub addresses: 004h and 005h) This sets the internal PLL counter reset period in 11 bits. Setting is possible in 2-dot units. When the number of dot clocks per 1H is N, set the "(N – 2)/2" value. When HR = 0, free-running occurs at the above N. When HR = 1, if the next HDIN is not input before the internal PLL counter counts up to 2047, free-running mode is established and free-running occurs at N. When HDIN is input, free-running is canceled and normal operation is established. (3) VFRRN[10:2] (sub address: 004h) This sets the number of lines in 9 bits during vertical free running. Setting is possible in 4-line units. To have operation run freely at M lines, set the "(M – 4)/4" value. If the next VDIN is not input before the internal vertical line counter counts up to 2047, free-running mode is established. When VDIN is input, free-running is canceled and normal operation is established. (d) Scan direction settings RGT and DWN (sub address: 000h) These settings switch the scan directions of the LCD panel. Setting value: 1 = Forward scan, 0 = Reverse scan When CTRL (Pin 148) is low, RGT (Pin 136) and DWN (Pin 147) function as output pins, and the data set in the respective registers is reflected. When CTRL is high, this setting is ignored, RGT and DWN function as input pins, and are reflected to internal operation. (e) Register parallel output settings PO1, PO2, PO3, PO4 and PO5 (sub address: 000h) These set the register setting parallel output. Setting value: 1 = High is output, 0 = Low is output The set data is reflected to the output pins PO1 (Pin 154), PO2 (Pin 153), PO3 (Pin 152), PO4 (Pin 164) and PO5 (Pin 166) of the same name. – 49 – CXD3511Q (f) Horizontal display position and horizontal direction pulse settings (1) HP[11:0] (sub addresses: 006h and 007h) HP[11:1] sets the horizontal pulse position for the LCD panel in 11 bits. The position can be set in 2-dot units using the internal pulse INT_HD generated from the front edge of HDIN as the reference. The HP setting range is from "0 to (N – 2)". If the HP value is set to the number of frequency divisions N or higher, the HP setting is ignored and "(N – 2)" is used as the setting value. The HST, PST, HCK1, HCK2, DCK1, DCK1X, DCK2, DCK2X, ENBL, ENBR, VSTL, VSTR, VCKL, VCKR, FRP, XFRP, PCG, PRG, BLK and HD2 horizontal timing pulses are linked according to the HP setting. The internal reference pulse INT_HD rises at the 5th clock from the front edge of the HDIN input, and all the pulses are synchronized using this as the reference. Increasing HP shifts the output positions of the linked pulses toward the rear of the time series. The example below shows the shortest output position from HDIN when HP is set to 000h. (Note that the output position changes according to the settings in (2) below.) HP[0] can shift the video in 1-dot units. See 3.

The respective rise and fall positions can be set in 2-dot units. Settings ending in "U" set the rise position, and settings ending in "D" set the fall position. Horizontal pulses are divided into the following two types. (A) CLP and HD1 → Pulses synchronized to the PLL counter Set the "(rise position/fall position – 10)/2" value. (B) PRG, SHST, DEN, PCG, ENBL, ENBR and HD2 → Pulses synchronized to the HP counter Set the "(rise position/fall position – HP setting value – 16)/2" value. An outline of each type is shown below. When ∗∗U and ∗∗D are set to the same value, "1" is output.

Setting value: 1 = Pulse is output, 0 = Output is fixed to "0" – 50 – CXD3511Q (g) Vertical display position setting VP[9:0] (sub address: 008h) This sets the vertical display start position in 10 bits. The position can be set in 1-line units using the front edge of VDIN as the reference. The VSTL/VSTR, VCKL/VCKR, FRP and XFRP pulse phases change by linking with this setting.

Setting value: 1 = Twice the HCK period width, 0 = HCK period width Set the width according to the LCD panel specifications. (2) PSTM (sub address: 002h) This sets the pulse width for dot sequential precharge start timing pulse PST.

HSTFIX HSTPOL RGT Output polarity 0 0 0 Positive 0 0 1 Negative 0 1 0 Negative 0 1 1 Positive 1 0 0 Negative 1 0 1 Negative 1 1 0 Positive 1 1 1 Positive – 52 – CXD3511Q (4) HSTPC[7:0], HSTPF[5:0], PSTPC[7:0] and PSTPF[5:0] (sub addresses: 015h to 018h) These set the HST and PST pulse phases. Reset is applied when the internal HP counter reaches "0", and the HST and PST pulse phases within 1H can be set at the HCK1 and HCK2 period, respectively, by HSTPC and PSTPC. HSTPF and PSTPF can set the HST and PST pulse phase relative to HCK1 and HCK2 in 1-dot units. Do not set HSTPC and PSTPC to 00h, as the pulses may not be output correctly in this case. The HSTPF and PSTPF values can be set up to "(HCKC × 2 – 2)". If higher values are set, the pulses are not output. Set the "(phase difference from HCK pulse)" value. The figures below show the timings for HSTPC: 04h and HSTPF: 04h, respectively. These timings are the same for the PST pulse. HSYNC 0 HP counter HP[11:0] HCK1 0 1 2 3 4 HST Setting prohibited MCLK HCK1 HST HSTPF: 04h (5) HSTOE and PSTOE (sub address: 02Dh) These set the HST and PST pulse output limits, respectively. Setting value: 1 = Pulse is output, 0 = Output is fixed to "0" – 53 – HSTPF[5:0] 5 6 7 CXD3511Q (i) HCK1 and HCK2 pulse settings (1) HCKC[5:0] (sub address: 019h) This sets the HCK1 and HCK2 period (LCD panel sampling period). Settings which result in an odd number for Tckw in the figure below are prohibited, so be sure to set a value that results in an even number. Set the "(Tckw – 1)" value according to the LCD panel specifications. When this setting is changed, the HST and PST pulse phases also change, so first set HCKC to the correct value and then make the HST and PST settings. Example setting values are shown in the table below. LCD panel Tckw HCKC setting SVGA, WXGA 6 clk 05h XGA, SXGA 12 clk 0Bh UXGA 24 clk 17h MCLK HCK1 Tckw 1 clk (2) HCKFIX and HCKPOL (sub addresses: 001h and 002h) These set the HCK pulse output polarity.

Using a multi-layer substrate and a solid ground is recommended. • Connect each power supply pin to GND via a ceramic chip capacitor of 0.1µF or more located as close to each pin as possible. • Do not use this IC under conditions other than the recommended operating conditions. • Absolute maximum rating values should not be exceeded even momentarily. Exceeding ratings may damage the device, leading to eventual breakdown. • This IC has a MOS structure which is easily damaged by static electricity, so thorough measures should be taken to prevent electrostatic discharge. • Since this IC utilizes a MOS structure, it may latch up due to excessive noise or power surge greater than the maximum rating of the I/O pins, interface with two power supplies of another circuit, or the order in which power is supplied to circuits. Make a thorough study of measures against the possibility of latch up before use. • When the initialization of this IC is performed at power-on, system clear cancellation is performed after the supply voltage is set in the range of the recommended operating conditions and stabilized. Keep in mind that the internal circuit may not be initialized correctly if system clear cancellation is performed before the supply voltage is set in the range of the recommended operating conditions. • When designing the substrate, take sufficient care for the surrounding temperature and heat radiation, and make sure the IC junction temperature does not exceed the maximum value. • Be sure to make the number of dot clocks input to the CXD3511Q in 1H an even number. Note that if there is an odd number of dot clocks, the internal phase compensation PLL will not operate properly. • Be sure to make a thorough evaluation of any items not listed in this data sheet. – 77 – CXD3511Q Application Circuit CTRL From A/D converter Auxiliary pulse To S/H driver To LCD panel To LCD panel To D/A converter +2.5V +3.3V 10µ 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ 10µ VSTR VCKR 181 R1IN2 182 R1IN1 R1OUT7 120 R1OUT6 119 183 R1IN0 R1OUT5 118 184 R2IN7 R1OUT4 117 185 R2IN6 R1OUT3 116 VSS 115 186 VDD2 From A/D converter 0.1µ 0.1µ 188 R2IN5 R1OUT2 113 189 R2IN4 R1OUT1 112 190 R2IN3 R1OUT0 111 191 R2IN2 R2OUT9 110 192 R2IN1 R2OUT8 109 193 R2IN0 R2OUT7 108 194 G1IN7 R2OUT6 107 195 G1IN6 R2OUT5 106 196 G1IN5 R2OUT4 105 197 VDD1 R2OUT3 104 198 VSS R2OUT2 103 199 G1IN4 VSS 102 200 G1IN3 VDD1 101 201 G1IN2 VDD2 100 202 G1IN1 R2OUT1 99 203 G1IN0 R2OUT0 98 204 G2IN7 G1OUT9 97 205 G2IN6 G1OUT8 96 206 G2IN5 G1OUT7 95 207 G2IN4 G1OUT6 94 208 G2IN3 G1OUT5 93 209 VDD1 G1OUT4 92 210 VSS G1OUT3 91 212 G2IN1 VDD1 89 213 G2IN0 G1OUT2 88 214 B1IN7 G1OUT1 87 215 B1IN6 G1OUT0 86 216 B1IN5 G2OUT9 85 217 B1IN4 VDD2 84 218 B1IN3 G2OUT8 83 219 B1IN2 G2OUT7 82 220 B1IN1 G2OUT6 81 221 VDD1 G2OUT5 80 222 VSS G2OUT4 79 224 B2IN7 VDD1 77 225 B2IN6 G2OUT3 76 226 B2IN5 G2OUT2 75 227 B2IN4 G2OUT1 74 228 B2IN3 G2OUT0 73 229 B2IN2 B1OUT9 72 230 B2IN1 B1OUT8 71 231 B2IN0 B1OUT7 70 232 R1OSD1 B1OUT6 69 233 R1OSD0 B1OUT5 68 0.1µ 0.1µ VSS 67 234 VDD2 VDD2 66 235 VSS 237 G1OSD0 B1OUT3 64 238 B1OSD1 B1OUT2 63 239 B1OSD0 B1OUT1 62 B1OUT0 61 10µ 0.1µ B2OUT9 B2OUT8 B2OUT7 B2OUT6 B2OUT5 VSS VDD2 B2OUT4 B2OUT3 B2OUT2 B2OUT1 B2OUT0 VSS CLKOUT VSS PLLDIV VSS VDD1 VDD2 CLKN CLKP VDD1 VDD1 CLKC VSS VSS VDIN HDIN VSS XCLR3 XCLR2 XCLR1 PDAT0 VDD1 PDAT1 PDAT2 PDAT3 PDAT4 PDAT5 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 VSS B2OSD0 8 VDD2 B2OSD1 7 PDAT6 VSS 6 PDAT7 VDD2 5 PDAT8 G2OSD0 4 PDAT9 G2OSD1 3 PCLK R2OSD0 2 PCTL R2OSD1 1 YS2 YS1 240 YM1 CLKSEL2 B1OUT4 65 CLKSEL1 236 G1OSD1 YM2 OSD input 0.1µ VSS 78 223 B1IN0 0.1µ 0.1µ VSS 90 211 G2IN2 0.1µ 0.1µ VDD2 114 187 VSS 10µ 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ GND OSD input Parallel data input To D/A converter CLKOUT +3.3V CLKN CLKP 10k CLKC +3.3V VDIN1 1µ 1µ GND GND PLLDIV 1µ CLKSEL2 10k CLKSEL1 10k HDIN1 Application circuits shown are typical examples illustrating the operation of the devices.
