CTRL Up/down and/or right/left inversion control signal selection setting. (For the DWN and RGT control signals, Pins 5 and 6 are selected when CTRL is H, and the settings from the internal register made via the serial interface are selected when CTRL is L.) DOUT00 to DOUT25 Digital data outputs. The data input to the DAC is output as is when OLIM (Pin 33) is L. Normally, output is not performed. Set OLIM to H and leave these open. 31 DACKO 32 DACKI Internal DAC clock input/output. DAC clock generated inside the IC is output from DACKO. Normally, input this DACKO output to DACKI. 33 OLIM Digital data output limiter. When OLIM is L, the data input to the DAC is output from the DOUT00 to DOUT25 output pins. When OLIM is H, these output pins go to high impedance state. 36, 41, 46 DACO2, 1, 0 Analog outputs from the internal DAC. The output impedance varies from several ten to several thousand Ω depending on the output voltage level, so connect these pins to BFIN2, 1 and 0 (buffer inputs), respectively. 37, 42, 47 BFIN2, 1, 0 Internal operational amplifier buffer inputs. Connect to DACO2, 1 and 0, respectively. 38, 43, 48 AOUT2, 1, 0 Analog correction signal outputs 40 VRL DAC L side reference voltage input (Input via buffer.) 44 VRH DAC H side reference voltage input (Input via buffer.) 57 SCTR 58 SCLK 59 SDAT 60 HSYNC This pin is a reference of horizontal output timing. Normally, input horizontal sync signal. 61 XCLR System clear. Internal register is initialized by setting to L. Input pins are pulled up to H internally. 63 CKI Master clock input. Input level is TTL. 64 SLCK Clock switching (H: Clock obtained by 1/2 frequency-dividing CKI using the internal frequency divider is selected. L: CKI input is selected. The selected clock is an internal master clock.) 7 11 to 16, 18 to 23, 25 to 30 Serial control inputs. Timing control and correction point data are all set by these pins. For details, see page 12 "Serial Transfer Operation". 17, 35, 49, 62 DVSS 24, 34, 56 DVDD 39 AVSS 45 AVDD Power supply inputs. Do not raise either analog power supply or digital power supply. –9– CXD3503R Clock input (CKI: Pin 63) The master clock input (CKI: Pin 63) of this IC supports TTL level input. In addition, two modes can be set: a mode in which the CKI is used as is for the internal master clock (SLCK (Pin 64): L) and a mode in which CKI is halved using the internal frequency divider (SLCK: H). In the latter mode, all internal operation is at 1/2 clock, so "clock" in the description below refers to this 1/2 clock when SLCK is H. Internal operation is at a frequency up to 41 MHz, so when inputting a clock faster than this to CKI1, be sure to set SLCK to H. selector D Q b XQ a Internal master clock (41MHz or less) s CKI SLCK HSYNC, VST, HST Input a standard horizontal sync signal to the input HSYNC (Pin 60). At this time, the input polarity is not fixed and is set by the serial data setting HSYNCPOL. In addition, make sure the VST and HST pulses satisfy the following phase relationship. However, when not using pulse eliminator display, HST (Pin 4) can be fixed to H level. Normally input the VST pulse to the LCD panel for the VST input. HSYNC toVst VST toHst HST toDisp Blanking portion Video signal toVst: VST shall rise 20 clocks or more after the front edge of HSYNC, and after the HST pulse. toHst: The front edge of HST shall follow the rear edge of HSYNC toDisp: There shall be 1.5H or more from the rise of VST to the start of the video signal. The Sony timing generator ICs (CXD2464R, CXD3500R) pulses of the same name satisfy the above conditions. System clear pin input Set the system clear pin (XCLR: Pin 61) to L and apply a forced reset in order to initialize the internal circuits during power-on. – 10 – CXD3503R Description of Output Correction Signal Operation Horizontal direction The correction data set in the SRAM by serial transfer is arithmetically processed inside the IC to determine the output position corresponding to the value set by serial register HP7 to 0 using the front edge of HSYNC as the reference. Interpolation is not performed for the horizontal direction, and interpolated data is output at the cycle set by serial register HINT7 to 0 for the vertical direction. In addition, the maximum amplitude of the correction signal output voltage is determined by VRH (Pin 44) and VRL (Pin 40). The internal DAC outputs at the resistive potential division (VRH to VRL: 213Ω typ.), so be sure to input to VRH and VRL via buffers having current capacity. HSYNC Set by HINT7 to 0 Set by HP7 to 0 DACKO/I DOUT VRH DACO VRL The internally generated digital data DOUT is input to the internal D/A converter, latched by the D/A converter clock input from DACKI, and output from DACO2, 1 and 0 as an analog signal. Note) If edges remain, these level differences may appear as vertical stripes. Therefore, when using this as a correction signal, be sure to eliminate the edges using an LPF, etc. before input to the CXA2111R or CXA2112R. Vertical direction The vertical correction points set in the SRAM are arithmetically processed inside the IC to output interpolated data for the lines other than correction points. m m+1 n n+1 fm, n fm + 1, n 1 (fm fm, n + a + 1, n – fm, n) 2 fm, n + a (fm + 1, n – fm, n) fm, n + a–1 a (fm + 1, n – fm, n) VINT line(s) 1 fm, n + 1 + a (fm + 1, n + 1 – fm, n + 1) 2 fm, n + 1 + a (fm + 1, n + 1 – fm, n + 1) fm, n + 1 + a' lines a–1 a (fm + 1, n + 1 – fm, n + 1) fm + 1, n fm + 1, n + 1 fm, n: Correction data for point (m, n) – 11 – Vertical correction point interval Set by VINT4 to 0 and ANM5 to 0 Assuming ANM5 to 0 = a, a' = VINT × a CXD3503R Serial Transfer Operation Control method The operation timing of this IC is controlled by serial data. The control data is divided into 8-bit units. The first 8 bits are the main address, the next 8 bits are the sub address, and the subsequent data is 8-bit data blocks. The main address specifies which of the blocks in the table below are to be set. Data is set in the blocks indicated by "1", so if the main address is set to "0F", the subsequent data is set in all data blocks. In addition, the value set in the sub address sets the initial write address in the block specified by the main address. Thereafter, the write address is incremented by +1 while SCTR is L for each 8 bits of data from the address set by the sub address. This makes it possible to set only the necessary data from an optional address. The data set by serial register INIT5 to 0 is output in place of the correction data during serial transfer.

The correction point data set in the SRAM is reflected to the outputs of the corresponding numbers. Correction point data 0, 1 and 2 Correction point data is set in the 6-bit × 208 words (16 horizontal points, 13 vertical points) SRAM. The set correction data undergoes vertical interpolation and other arithmetic processing, and is then reflected to the DACO0, 1 and 2 outputs, respectively. The correction point data is 6 bits, and is set in D5, 4, 3, 2, 1 and 0. Setting to D7 and 6 is invalid. See the figure on page 13 for the relationship between the correction point data position and the SRAM address. Example) When the main address is set to 04 and the sub address is set to 08, data is written from address 08 of correction point data 2 (SRAM2), then the address is automatically incremented and written to the SRAM. – 12 – CXD3503R Timing control data Main address 08h Sub address D7 D6 D5 D4 D3 D2 D1 D0 00h HB3 HB2 HB1 HB0 HE3 HE2 HE1 HE0 01h VB3 VB2 VB1 VB0 VE3 VE2 VE1 VE0 02h HP7 HP6 HP5 HP4 HP3 HP2 HP1 HP0 03h HINT7 HINT6 HINT5 HINT4 HINT3 HINT2 HINT1 HINT0 04h — — — — VP3 VP2 VP1 VP0 05h — — — VINT4 VINT3 VINT2 VINT1 VINT0 06h — — ANM5 ANM4 ANM3 ANM2 ANM1 ANM0 07h — 1/A6 1/A5 1/A4 1/A3 1/A2 1/A1 1/A0 08h HSOFF HPOL VSPOL DWN RGT 09h STBY1 STBY0 INIT5 INIT4 INIT3 DACKP2 DACKP1 DACKP0 INIT2 INIT1 INIT0 —: Setting invalid Data settings HB3 to 0, HE3 to 0, VB3 to 0, VE3 to 0 These set the range of the correction point data to be used. Expressed in model format, the correction points appear as shown in the figure below. To use only the shaded area, set HB: 2, HE: D, VB: 1 and VE: B. Normally set HB: 0, HE: F, VB: 0 and VE: D (16 × 13). Horizontal direction Address 00 Specified by HB Specified by HE 0F Vertical direction Specified by VB Specified by VE C0 CF Dots in the lattice above represent correction points, and the white circles are the data settings. – 13 – CXD3503R HP7 to 0 This sets the correction signal output start position in the horizontal direction. The timing until the start of correction signal output is set using the front edge of HSYNC as the reference. However, do not set HP7 to 0 to a value of 54 or less, as the arithmetically processed correction signal may not be output correctly in this case. In addition, the waveform may be disturbed by the HP and HINT values and the VST phase. In these cases, eliminate the disturbance by adjusting the HP and DACKO phase. Set by HP7 to 0 HSYNC DACO HINT7 to 0 This sets the correction point interval in the horizontal direction. Normally, when using 16 points in the horizontal direction, calculate the number of clocks at which the horizontal period can be divided into 16 sections taking into account the input clock and the system clock speed, and then set this value – 1. However, do not input a value of 11 or less to HINT7 to 0, as the internal arithmetic processing may not be able to keep up and the correct value may not be output in this case. Example 1) Inputting a dot clock 40MHz signal to a SVGA panel (800 × 600) If 1/2 the dot clock is input as the master clock and the mode without internal 1/2 frequency division (SLCK: L) is used: HINT = (800 ÷ 16 ÷ 2) – 1 = 24 Example 2) Inputting a dot clock 65MHz signal to a XGA panel (1024 × 768) If 1/2 the dot clock is input as the master clock and the mode with internal 1/2 frequency division (SLCK: H) is used: HINT = (1024 ÷ 16 ÷ 4) – 1 = 15 Set by HINT Internal clock DACO fm, n fm, n + 1 HINT = 15 – 14 – CXD3503R VP3 to 0 This sets the correction signal output start position in the vertical direction. The number of line counted from the front edge of the VST pulse at which vertical arithmetic processing of the correction signal starts is set. The correction data for the initial line is output continuously only for the number of lines set by VP. VINT4 to 0 This sets the arithmetic processing interval for vertical correction. Vertical correction arithmetic processing is performed every number of lines set by VINT. Normally set arithmetic processing for each line (VINT = 1). ANM5 to 0 This sets the correction point interval in the vertical direction. There are 13 vertical correction points with respect to the actual panel display area switching, so this sets the number of lines at which correction points are spaced for the internal arithmetic processing. Example) To use the full correction point data in the vertical direction, set the correction point interval ANM as follows. SVGA panels: ANM = 600 ÷ 12 = 50 (110010) XGA panels: ANM = 76 ÷ 12 = 64 (000000) 1/A6 to 0 This sets the inverse of ANM. Set the 6th to 12th digits below the decimal point in binary format with 7 bits. Linear interpolation with an accuracy of 1 bit is performed using this setting value. Example) ANM = 50: 1/50 (decimal) = 0.000001010010 (binary) Set the 6th to 12th digits. Example) ANM = 64: 1/64 (decimal) = 0.000001000000 (binary) Set the 6th to 12th digits. VST HSYNC DACO 0 0 0 0 1 1 2 2 ANM – 1 ANM – 1 VP VINT VINT VINT ANM – 15 – VINT 0’ 0’ CXD3503R HSOFF This is the correction ON/OFF setting. When H, correction is on; when L, correction is off and the INIT5 to 0 data is output constantly. Normally set HSOFF to H. HPOL This sets the HSYNC input signal polarity. Set HPOL to H for positive polarity, and to L for negative polarity. Be sure to set the polarity correctly in accordance with the input signal. VSPOL This sets the VST input signal polarity. Set VSPOL to H for positive polarity, and to L for negative polarity. Be sure to set the polarity correctly in accordance with the input signal. The Sony timing generator ICs CXD2464R and CXD3500R output an inverse polarity VST pulse for up/down inverse drive of a SVGA panel. Therefore, take special care for the VST polarity when using this IC with a SVGA panel. DWN, RGT DWN and RGT set up/down and right/left inversion, respectively. Normal scan is supported when DWN is H and RGT is H, and up/down and/or right/left inversion of the panel is supported by reading the correction data set in the RAM in the reverse order when these are set to L, respectively. These settings can be controlled from the external pins of the same name DWN (Pin 5) and RGT (Pin 6) by setting CTRL (Pin 7) to H. In this case these serial settings are invalid. DACKP2 to 0 This sets the DAC clock phase. Normally set to "2" to satisfy the internal DAC clock and data setup/hold specifications. STBY1 and 0 This is the standby setting. Standby mode results when STBY1, 0 are set to H, L. At this time, the internal clock is supplied only to the serial interface block, and operation of all other blocks is stopped. Buffer outputs AOUT2, 1 and 0 and digital outputs DOUT25 to 20, 15 to 10 and 05 to 00 are all high impedance at this time. INIT5 to 0 This sets the DACO output level when correction is off. When serial data HSOFF is set to L, the data for this setting is output regardless of the correction data set in the RAM. – 16 – 70 80 90 D20 100 110 HINT 120 D21 130 140 – 17 – DACO2 DACO2 DACO2 VRL VRH VRL VRH VRL VRH D00 D10 D01 D11 D01 D00 HP 60 DOUT05 to 00 50 D11 40 D10 30 DOUT15 to 10 20 D21 10 D20 0 DOUT25 to 20 DACKO (I) (BLK) HSYNC MCK Timing Chart 160 170 180 D02 D12 D02 D12 D22 D03 D13 D23 Effective video signal D22 150 D03 D13 D23 190 210 D04 D14 D24 200 D04 D14 D24 220 230 CXD3503R CXD3503R Application Circuit To CXA2111R Bright pins (Pins 30, 31 and 32) LPF LPF LPF Analog 5V Digital 5V OLIM DVSS1 DVDD1 DACO2 BFIN2 AVSS AOUT2 VRL BFIN1 DACO1 VRH AOUT1 AVDD BFIN0 DACO0 AOUT0 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 49 DVSS2 DACKI 32 50 NC DACKO 31 51 NC DOUT25 30 52 NC DOUT24 29 53 NC DOUT23 28 54 NC DOUT22 27 55 NC DOUT21 26 56 DVDD2 DOUT20 25 CXD3503R 57 SCTR DOUT14 22 60 HSYNC DOUT13 21 61 XCLR DOUT12 20 62 DVSS3 DOUT11 19 63 CKI1 DOUT10 18 64 SLCK DOUT05 DOUT04 TEST1 DOUT03 TEST0 DOUT02 CTRL DOUT01 RGT DOUT00 DWN TEST2 DVSS0 17 HST From PLL CXA3106(A)Q 59 SDAT VST 1µ/16V DOUT15 23 NC 10k DVDD0 24 58 SCLK NC Serial I/F 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 From TG CXD3500R Application circuits shown are typical examples illustrating the operation of the devices.
