CXA2076Q
Description of Operation 1. Power-on sequence The CXA2076Q does not have an internal power-on sequence. Therefore, power-on sequence is all controlled by the set microcomputer (I2C bus controller). 1) Power-on The IC is reset and the RGB outputs are all blanked. Hdrive starts to oscillate, but oscillation is at the maximum frequency (16kHz or more) and is not synchronized to the input signal. Output of vertical signal VTIM starts, but Vdrive is DC output. Bus registers which are set by power-on reset are as follows. AGING RON GON BON PICON VOFF VFREQ FHHI HSIZESW CD-MODE AKBOFF = 0: All white output aging mode OFF = 0: Rch video blanking ON = 0: Gch video blanking ON = 0: Bch video blanking ON = 0: RGB all blanking ON = 1: VDRIVE output stopped mode = 0: Automatic identification mode (identification starts at 50Hz) = 1: H oscillator maximum frequency mode = 0: Normal = 0: Automatic selection mode of the countdown mode = 0: AKB mode
2) Bus register data transfer The register setting sequence differs according to the set sequence. Register settings for the following sequence are shown as an example. Set sequence Power-on Degauss VDRIVE oscillation CXA2076Q register settings Reset status in 1) above. Reset status in 1) above. The CRT is degaussed in the completely darkened condition. The IC is set to the power-on initial settings. (See the following page.) A sawtooth wave is output to VDRIVE and the IC waits for the vertical deflection to stabilize. The HDRIVE oscillator frequency goes to the standard frequency. PICON is set to 1 and a reference pulse is output from Rout, Gout and Bout. Then, the IC waits for the cathode to warm up and the beam current to start flowing. Status register IKR is monitored. IKR = 0: No cathode current IKR = 1: Cathode current Note that the time until IKR returns to 1 differs according to the initial status of the cathode. RON, GON and BON are set to 1 and the video signal is output from Rout, Gout and Bout. - 33 -

2. Various mode settings The CXA2076Q contains bus registers for deflection compensation which can be set for various wide modes. Wide mode setting registers can be used separately from registers for normal picture distortion adjustment, and once deflection adjustment has been performed in full mode, wide mode settings can be made simply by changing the corresponding register data. * VDRIVE signal picture distortion adjustment registers V-SIZE, V-POSITION, S-CORR, V-LIN * E/WDRIVE signal picture distortion adjustment registers H-SIZE, PIN-COMP, PIN-PHASE, UP-CORNER-PIN, LO-CORNER-PIN * Wide mode setting registers V-ASPECT, ZOOMSW, HBLKSW, V-SCROLL, JMPSW, HSIZESW, UP-VLIN, LO-VLIN, LEFT-BLK, RIGHT-BLK

Examples of various modes are listed below. These modes are described using 570 (NTSC: 480) lines as the essential number of display scanning lines. Wide mode setting register data is also listed, but settings may differ slightly due to IC variation. The standard setting data differs for 16:9 CRTs and 4:3 CRTs. Register V-ASPECT V-SCROLL ZOOMSW UP-VLIN LO-VLIN JMPSW HSIZESW HBLKSW LEFT-BLK RIGHT-BLK 16:9 CRT 0h 1Fh 1 0h 0h 0 0 0 7h 7h 4:3 CRT 2Fh 1Fh 0 0h 0h 0 0 0 7 7h
1) 16:9 CRT full mode This mode reproduces the full 570 (NTSC:480) lines on a 16:9 CRT. 4:3 images are reproduced by stretching the picture to the left and right. Normal images are compressed vertically, but 16:9 images can be reproduced in their original 16:9 aspect ratio with a video source which compresses (squeezes) 16:9 images to 4:3 images. The register settings are the 16:9 CRT standard values. 2) 16:9 CRT normal mode In this mode, 4:3 images are reproduced without modification. A black border appears at the left and right of the picture. In this mode, the H deflection size must be compressed by 25% compared to full mode. The CXA2076Q permits compression with a register (HSIZESW) that compresses the H size by 25%. Because excessive current flows to the horizontal deflection coil in this case, adequate consideration must be given to the allowable power dissipation, etc., of the horizontal deflection coil in the design of the set. In addition, this concern can also be addressed through measures taken external to the IC, such as by switching the horizontal deflection coil. Full mode should be used when using memory processing to add a black border to the video signal. H blanking of the image normally uses the flyback pulse input to AFCPIN (Pin 38). However, the blanking width can be varied according to the control register setting when blanking is insufficient for the right and left black borders. The following three settings are added to the 16:9 CRT standard values for the register settings. HBLKSW = 1 LEFT-BLK = Adjustment value RIGHT-BLK = Adjustment value The H angle of deflection also decreases, causing it to differ from the PIN compensation amount during H size full status. Therefore, in addition to the wide mode registers, PIN-COMP must also be readjusted only for this mode. 3) 16:9 CRT zoom mode In this mode, 4:3 images are reproduced by enlarging the picture without other modification. The top and bottom of normal 4:3 images are lost, but almost the entire picture can be reproduced for vista size video software, etc. which already has black borders at the top and bottom. The enlargement ratio can be controlled by the V-ASPECT register, and enlarging the picture by 33% compared to full mode allows zooming to be performed for 4:3 images without distortion. In this case, the number of scanning lines is reduced to 430 lines compared to 570 lines for full mode. The zooming position can be shifted vertically by the V-SCROLL register. V blanking of the image normally begins from V sync and continues for 2H after the AKB reference pulse, and the top and bottom parts are also blanked during this mode. Adjust the following two registers with respect to the 16:9 CRT standard values for the register settings. V-ASPECT = 2Fh V-SCROLL = 1Fh or user control - 37 -
CXA2076Q
4) 16:9 CRT subtitle-in mode When CinemaScope size images which have black borders at the top and bottom of the picture are merely enlarged with the zoom mode in 3) above, subtitles present in the black borders may be lost. Therefore, this mode is used to super-compress only the subtitle part and reproduce it on the display. Add the LO-VLIN adjustment to the zoom mode settings for the register settings. V-ASPECT = 2Fh V-SCROLL = 1Fh or user control LO-VLIN = Adjustment value The LO-VLIN register causes only the linearity at the bottom of the picture to deteriorate. Therefore, UP-VLIN should also be adjusted if the top and bottom of the picture are to be made symmetrical. Since the picture is compressed vertically, the number of scanning lines exceeds 430 lines. 5) 16:9 CRT V compression mode This mode is used to reproduce two 4:3 video displays such as for PandP. The V size must be compressed to 67% in order to reproduce two displays on a 16:9 CRT without distortion using 480 scanning lines, and this can be set by JMPSW. Compression is performed after the AKB reference pulse, so the reference pulse remains in the overscan position. The V blanking width after the reference pulse becomes larger than normal and can be varied by the VBLKW register. During this mode, the bottom V blanking width is also expanded to 3H wider than normal so that the bottom of the picture is not overscanned. 16:9 CRT standard values are used with only the JMPSW setting changed for the register settings. JMPSW = 1 6) 16:9 CRT wide zoom mode This mode reproduces 4:3 video software naturally on wide displays by enlarging 4:3 images without other modification and compressing the parts of the image which protrude from the picture into the top and bottom parts of the picture. The display enlargement ratio is controlled by V-ASPECT, and the compression ratios at the top and bottom of the picture are controlled by UP-VLIN and LO-VLIN. Adjust the following three registers with respect to the 16:9 CRT standard values for the register settings. V-ASPECT = Adjustment value UP-VLIN = Adjustment value LO-VLIN = Adjustment value 7) 4:3 CRT normal mode This is the standard mode for 4:3 CRTs. The register settings are the 4:3 CRT standard values. 8) 4:3 CRT V compression mode This mode is used to reproduce M-N converter output consisting of 16:9 images expanded to a 4:3 aspect ratio and other squeezed signals without distortion on a 4:3 CRT. The V size must be compressed to 75% in order to reproduce a 4:3 squeezed signal at a 16:9 aspect ratio without any distortion. Compressing the V size with the JMPSW register used in mode 5) above, compresses the V size to 67%. Therefore, V-ASPECT is set to enlarge the V size by 8%. AKB reference pulse handling and V blanking are the same as for mode 5) above. 4:3 CRT standard values are used with the V-ASPECT and JMPSW settings changed for the register settings. V-ASPECT = 3Fh JMPSW =1

3. Signal processing The CXA2076Q is comprised of sync signal processing, H deflection signal processing, V deflection signal processing, and Y/C/RGB signal processing blocks, all of which are controlled by the I2C bus. 1) Sync signal processing Pin 48 (SYNC OUT) outputs at 2Vp-p either the internal signal (CVIN/YIN) selected by the internal video switch, or the external sync signal input from Pin 56 (EXT SYNC IN). This selection is controlled by the I2C bus. The signal output from Pin 48 is buffered by a PNP Tr. and is then input to HSIN (Pin 47) or VSIN (Pin 46) through a suitable filter. The Y signals input to Pins 46 and 47 are sync separated by the horizontal and vertical sync separation circuits. The resulting horizontal sync signal and the signal (FH = 15625Hz or 15734Hz) obtained by frequency dividing the 32FH-VCO output using the ceramic oscillator (frequency 500kHz or 503.5kHz) by 32 are phasecompared, the AFC loop is constructed, and an H pulse synchronized with the H sync is generated inside the IC. Adjustment of the H oscillator frequency is unnecessary. When the AFC is locked to the H sync, 1 is output to the status register (HLOCK) and that can be used to detect the presence of the video signal. The vertical sync signal is sent to the V countdown block where the most appropriate window processing is performed to obtain V sync timing information which resets the counter. AKB and other V cycle timing are then generated from this reset timing. 2) H deflection signal processing The H pulse obtained through sync processing is phase-compared with the H deflection pulse input from Pin 38 to control the phase of the HDRIVE output and the horizontal position of the image projected on the CRT. In addition, the compensation signal generated from the V sawtooth wave is superimposed, and the vertical picture distortion is compensated. The H deflection pulse is used for H blanking of the video signal. When the pulse input from Pin 38 has a narrow width, the pulse generated by the IC can be added to the H deflection pulse and used as the H blanking pulse (HBLKSW). Pin 38 is normally pulse input, but if the pin voltage drops to the GND level, HDRIVE output stops and 1 is output to the status register (XRAY). To release this status, turn the power off and then on again. 3) V deflection signal processing The V sawtooth wave is generated at the cycle of the reset pulse output from the countdown system. After performing wide deflection processing for this sawtooth wave, picture distortion adjustment is performed by the VDRIVE and E/WDRIVE function circuits and the signal is output as the VDRIVE and E/WDRIVE signals. 4) Y signal processing Either CVIN, input from Pin 53, or YIN, output from Pin 55, is selected by the video switch and then is passed to the Y signal processing circuit as the Y signal. The input level is 1Vp-p. The Y signal passes through the subcontrast control, the trap for eliminating the chroma signal, the delay line, the sharpness control, the clamp and the black expansion circuits, and is then output to Pin 5 as YOUT. The differentiated waveform of the Y signal, advanced for about 200ns from YOUT is output from Pin 49 as the VM signal. The delay time is set by the bus register (DL). When CVIN is selected, the trap is on; when YIN is selected, the trap is off. The f0 of the internal filter is automatically adjusted within the IC. Because the f0 of the filter is not specified when the color killer function is operating, turn the trap off if there are any difficulties. In addition, the f0 of the trap will be affected slightly by variations among IC, so fine adjustment through the I2C bus (TRAP-F0) may be required. - 40 -
CXA2076Q
5) C signal processing The CVBS signal or chroma signal (specified input level: burst level of 300mVp-p) selected by the video switch passes through the ACC, TOT, chroma amplifier and demodulation circuits, becomes the R-Y and B-Y color difference signals, and is inverted for output on Pins 3 and 4. The color difference signals are averaged together by the external 1H delay line, and are input to Pins 7 and 8. Both color difference signals are clamped together with the Y signal input to Pin 5. They are then combined with the G-Y signal in the color control and axis control circuits. After Y/C mixing, the signals become the RGB signals. If the burst level goes to -35dB or less with respect to the specified input level, the color killer operates. In addition, the color system (PAL/NTSC) and the subcarrier frequency (4.43MHz/3.58MHz) are automatically identified according to the input chroma signal, and the internal VCO, demodulation circuit, axis control circuit, etc., are adjusted automatically. Furthermore, SECAM signals can also be identified if an external SECAM decoder is connected to Pin 1. In this case, Pins 3 and 4 and the SECAM decoder color difference output are linked together directly, and automatically one side goes to high impedance, the other goes to low impedance according to the input chroma signal, and then they are input to the external 1H delay line. System identification can be set to automatic or forced mode by the I2C bus (XTAL and COLOR SW). The color system is output to the status register (COLOR SYS). 6) RGB Signal processing The RGB signals obtained from the Y/C block pass through the half-tone switch circuit (YM SW), the two switch circuits for the external RGB signals (YS1, YS2 SW), the picture control, dynamic color, gamma compensation, clamp, brightness control, drive adjustment, cut-off adjustment and auto cut-off circuits, and are output to Pins 22, 24 and 26. The RGB signals input to Pins 12, 13, 14, 17, 18, and 19 are 100 IRE, 100% white 0.7Vp-p signals, in accordance with the standard for normal video signals. If signals of 1.5Vp-p or more are input to Pins 17, 18, and 19, 67 IRE output is obtained (digital input). The voltage applied to Pin 28 (ABLIN) is compared with the internal reference voltage, integrated by the capacitor which is connected to Pin 29, and performs picture control and brightness control. In order to adjust the white balance (black balance), this IC has a drive control function which adjusts the gain between the RGB outputs and a cut-off control function which adjusts the DC level between the RGB outputs. Both drive control and cut-off control are adjusted by the I2C bus, with the Rch fixed and the G and Bch variable. An auto cut-off function (AKB) which forms a loop between the IC and CRT and performs adjustment automatically has also been added. This function can compensate for changes in the CRT with time. Auto cutoff operation is as follows. * R, G and B reference pulses for auto cut-off, shifted 1H each in the order mentioned, appear at the top of the picture (actually, in the overscan portion). The reference pulse uses 1H in the V blanking interval, and is output from each R, G and B output pin. * The cathode current (Ik) of each R, G and B output is converted to a voltage and input to Pin 27. * The voltage input to Pin 27 is compared with the reference voltage in the IC, and the current generated by the resulting error voltage charges the capacitors connected to Pins 21, 23 and 25 for the reference pulse interval and is held during all other interval. * The loop functions to change the DC level of the R, G and B outputs in accordance with the capacitor pin voltage so that the Pin 27 voltage matches the reference voltage in the IC. The Rch for the reference voltage in the IC is fixed and the G and Bch are cut-off controlled by the I2C bus. During G/B-CUTOFF center status, the loop functions so that the Rch for the reference pulse input to Pin 27 is 1Vp-p and the G and Bch are 0.81Vp-p. The reference pulse timing can be varied by the I2C bus. When AKB is not used, the IC can be set to manual cut-off mode with I2C bus settings. In this case, the DC level of the R, G and B outputs can be varied by applying voltages independently to Pins 21, 23 and 25. - 41 -
CXA2076Q
4. Notes on operation Because the RGB signals and deflection signals output from the CXA2076Q are DC direct connected, the board pattern must be designed consideration given to minimizing interference from around the power supply and GND. Do not separate the GND patterns for each pin; a solid earth is ideal. Locate the power supply side of the bypass capacitor which is inserted between the power supply and GND as near to the pin as possible. Also, locate the XTAL oscillator, ceramic oscillator and IREF resistor as near to the pin as possible, and do not wire signal lines near this pin. Drive the Y, external Y/color difference and external RGB signals at a sufficiently low impedance, as these signals are clamped when they are input using the capacitor connected to the input pin. DC bias is applied to the chroma signal within the IC. Input the chroma signal with low impedance via an external capacitor. Use a resistor (such as a metal film resistor) with an error of less than 1% for the IREF pin. Use a capacitor, such as an MPS (metalized polyester capacitor) with a small tan for SAWOSC. When using a line frequency FH of 15625Hz for the main clock (PAL-B, G, etc.), Murata's Ceralock CSB500F63 is recommended. This will yield a free-run frequency in the neighborhood of 15625Hz.
