VM OUT/ V PROT
Output of luminance signal differential waveform for VM (Velocity Modulation). The phase of VM output is synchronized to the phase of RGB output. It is approximately 250ns ahead of RGB output. This pin is also used for V protect signal input. When the large current (4mA) is forcibly drawn through this pin, all RGB output is blanked, and 1 is output to the status register VNG.

16
H deflection pulse input for H AFC. The 5Vp-p pulse is input via a capacitor. Since this pin is also used to input an X­RAY protect signal, a hold down function activates if this pin's voltage goes above a "7V cycle" and below 1V. If this occurs, HD output goes high impedance, RGB output is blanked, and 1 is output to the status register HNG. It is necessary to turn the IC's power OFF then ON again to cancel this status.
Pin No.

IK IN
CRT beam current input (cathode current IK). This current is converted into voltage within the IC. In order to eliminate any adverse effects exercised by CRT leak current (max. 100µA) for AKB operation, it is clamped at the V blanking interval. The AKB loop is activated by comparing the reference pulse component of this signal to the reference voltage within the IC. The RGB output cutoff can be varied using CUTOFF of the bus. The IK reference signal current can be controlled ±50% around a 13µA center. Since the beam current of the video section is large, be sure to attach a zener diode of about 4V to the pin to protect the IC.

Description of Operation
1. Power-On Sequence
The CXA2060BS does not have an internal power-on sequence. Therefore, all power-on sequences are controlled by the set microcomputer (I2C bus controller).
(1) Power-on
The IC is reset and the RGB outputs are all blanked. H drive starts to oscillate, but oscillation is at the maximum frequency (16kHz or more) and is not synchronized with the input signal in order to prevent FBT (flyback transformer for generating high voltage) H squealing. Output of vertical signal V TIM starts, but V drive is DC output. Bus registers which are set by power-on reset are as follows.
P ON = 0: RGB all blanked ON HD W = 0: Normal mode V ON = 0: V output stopped mode FH HIGH = 0: H oscillator maximum frequency mode AGING = 0: All white output aging mode OFF YUV OUT= 0
(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.

V drive oscillation The IC is set to the power-on initial settings. (See the following page.)
A sawtooth wave is output to V drive and the IC waits for the vertical deflection to stabilize. The H drive oscillator frequency goes to the standard frequency.
↓ ↓
AKB operation start R ON, G ON and B ON are set to 0. P ON is set to 1 and a reference pulse is
output from RGBOUT. Then, the IC waits for the cathode to warm up and the beam current to start flowing.
↓ ↓
AKB loop stable Status register IKR is monitored.
IKR = 0: Unstable
IKR = 1: Stable Note that the time until IKR = 1 is returned differs according to the initial status of the cathode. Also note that the time until IKR = 1 results may differ from the actual time until the cathode current stabilizes. It is recommended that video output start after IKR = 1 has been established for 1 or 2 seconds.
↓ ↓
Video output R ON, G ON and B ON are set to 1 and the video signal is output from RGBOUT.

2. Various Mode Settings
The CXA2060BS 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 picture distortion adjustment has been performed in full mode, wide mode settings can be made simply by changing the corresponding register.
• Vertical picture distortion adjustment registers V SIZE, V POSITION, S CORRECTION, V LINEARITY
• Horizontal picture distortion adjustment registers H SIZE, EW DC, PIN AMP, CORNER PIN, TRAPEZIUM, AFC BOW, AFC ANGLE, H POSITION
• Wide mode setting registers LEFT HBLK, RIGHT HBLK, ASPECT, HBLK, V UNDER SCAN, SCROLL, V ZOOM, UPPER VLIN, LOWER VLIN

Mode examples are given below. The 570 actual number of scanning lines displayed under PAL (480 lines for NTSC) will be used in the description. Data stored in the wide mode setting registers is also given. Note that actual adjustment values may differ slightly due to variations among different ICs. Standard setting data differs for 16:9 CRTs and 4:3 CRTs.
(Standard value)
Register 16:9 CRT 4:3 CRT
ASPECT 0h 2Fh SCROLL 1Fh 1Fh V ZOOM 1 0 UPPER VLIN 0h 0h LOWER VLIN 0h 0h V UNDER SCAN 0 0 HBLK 0 0 LEFT HBLK 7h 7h RIGHT HBLK 7h 7h
1) Full mode
This mode reproduces the full 570 (NTSC: 480) lines on a 16:9 CRT. Normal 4:3 images are compressed vertically, but in the case of a squeezed video source which compresses 16:9 images to 4:3 images, 16:9 images are reproduced in their original 16:9 aspect ratio. The register settings are the 16:9 CRT standard values.
2) Normal mode
In this mode, 4:3 images are reproduced without modification on a 16:9 CRT. 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 CXA2060BS performs compression with a register (EW DC) that compresses the H size. Because excessive current flows to the horizontal deflection circuit 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 switching the horizontal deflection coil. Full mode should be used when performing memory processing to add a black border to the video signal. H blanking of the image normally uses the flyback pulse input from HP/PROTECT (Pin 18). However, the blanking width can be varied according to the control register setting when blanking is insufficient for the right and left black borders. Change the following three settings with respect to the 16:9 CRT standard values for the register settings.
HBLK = 1 LEFT HBLK = Adjustment value
RIGHT HBLK = Adjustment value The H angle of deflection decreases, causing it to differ from the PIN compensation amount during H size full status. Therefore, in addition to the wide mode registers, PIN AMP must also be readjusted only for this mode.

CXA2060BS
3) Zoom mode
In this mode, 4:3 images are reproduced on a 16:9 CRT 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. Setting the ASPECT register to 2Fh (100%) 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 SCROLL register. V blanking of the image normally begins from V sync and continues for 2H after the AKB reference pulse, but the top and bottom parts which are lost are also blanked during this mode. Adjust the following two registers with respect to the 16:9 CRT standard values for the register settings.
ASPECT = 2Fh SCROLL = 1Fh or user control
4) Subtitle-in mode
When Cinema Scope images which have black borders at the top and bottom of the picture are merely enlarged with the zoom mode in 3) above, the 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 LOWER VLIN adjustment to the zoom mode settings for the register settings.
ASPECT = 2Fh SCROLL = 1Fh or user control
LOWER VLIN = Adjustment value LOWER VLIN causes the linearity at the bottom of the picture to deteriorate. Therefore, UPPER 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) Two-picture mode
This mode is used to reproduce two 4:3 video displays on a 16:9 CRT such as for P and P. To achieve this, the V size must be further compressed from the condition where ASPECT = 0 (V size 75%: full mode). This IC performs this compression with V UNDER SCAN. 16:9 CRT standard values are used with only V UNDER SCAN changed to 1 for the register settings.
V UNDER SCAN = 1
6) 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 ASPECT, and the compression ratios at the top and bottom of the picture are controlled by UPPER VLIN and LOWER VLIN. Adjust the following three registers with respect to the 16:9 CRT standard values for the register settings.
ASPECT = Adjustment value
UPPER VLIN = Adjustment value
LOWER 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.

CXA2060BS
8) V compression mode
This mode is used to reproduce M-N converter output consisting of 16:9 images expanded to 4:3 aspect ratio and other squeezed signals without distortion on a 4:3 CRT. In this case, the V size must be compressed to 75%. This is done using V UNDER SCAN in 5) above. Setting V UNDER SCAN to ON compresses the V size to 75%. Fine adjustment of the V size is possible by adding the ASPECT adjustment. 4:3 CRT standard values are used with the ASPECT and V UNDER SCAN settings changed for the register settings.
ASPECT = Adjustment V UNDER SCAN = 1

3. Signal Processing
The CXA2060BS consists of separate blocks for sync signal processing, H deflection signal processing, V deflection signal processing and Y/C and RGB signal processing, all controlled by an I2C bus.
1) Sync signal processing
The Y signal selected by the video switch is sync separated by a horizontal/vertical sync separation circuit. A phase comparison between the horizontal sync split signal obtained and the H VCO output signal is conducted and an AFC loop is configured, and an H pulse synchronized to H sync is created within the IC. When AFC is locked to H sync, 1 is output to the status register (H LOCK). This can be used to detect the presence of a video signal. The vertical sync split signal is sent to the V countdown block and V deflection timing is obtained by the appropriate window processing. V cycle timing such as the AKB reference pulse is generated using this V timing pulse. The V retrace timing pulse and sync split signal are output on V TIM (Pin 5) according to the V TIMSEL register setting.
2) H deflection signal processing
A phase comparison is conducted between the H pulse obtained from sync processing and the H deflection pulse input on Pin 18 (HP/PROTECT) and the horizontal position of the picture displayed on the CRT is controlled by controlling the phase of H drive output. The compensation signal created using the vertical sawtooth wave is superimposed and vertical picture distortion compensation is also performed. The H deflection pulse is used for H blanking of the video signal. If the width of the H deflection pulse is narrow, a pulse created by the IC can be added and the result used as the H blanking pulse (HBLK). Although Pin 18 is for normal pulse input, the pin is kept lowered to near GND level, H drive output is stopped and 1 is output to the status register (H NG). It is necessary to turn the IC's power OFF and ON again in order to cancel this status.
3) V deflection signal processing
The vertical sawtooth wave oscillates in sync with the V timing pulse cycle output by the countdown. After wide deflection processing is added to this sawtooth wave, it undergoes picture distortion adjustment by the function circuits V drive and EW drive, respectively, and the result is output as the V drive and EW drive signals.
4) Y signal processing
The Y/CVBS signal selected by the video switch is sent to the Y signal processing circuit. The Y signal is sent to the RGB signal processing circuit via a trap filter for eliminating the chroma signal, a delay line, sharpness control, clamp, and black expansion circuits. In addition, the output of the Y signal processing circuit can be monitored using Pin 32 (R2 IN) by setting register YUV OUT to 1. (At this time, be sure to connect a 10kΩ resistor to Vcc as a load for Pin 32.) Also, a differential waveform of the Y signal synchronized with YOUT (RGB OUT) is output from Pin 15 as VM OUT. When the CVBS signal is selected, set the C TRAP OFF register to 0 (trap filter ON), and when the Y signal split from Y/C separation is selected, set this register to 1 (trap filter OFF). The internal filter f0 is adjusted automatically within the IC. Since the filter f0 does not settle down while the color killer is operating, be sure to set the trap filter to OFF if it is an obstacle.

5) C signal processing
The TV, CVBS or chroma (PAL, NTSC) signals (specified input: burst level 300mVp-p) selected by the Video SW pass through an ACC, chroma band-pass filter, chroma amplifier, and demodulation circuit to form the color difference signals R-Y and B-Y. After being processed by 1HDL the signals are input to the RGB signal processing circuit. The output signals (color difference signals) of this C signal processing circuit can be monitored, just like Y output, using Pin 30 (B2 IN) and Pin 31 (G2 IN) by setting the register YUV OUT to 1. B-Y is output from Pin 30 (B2 IN) and R-Y is output from Pin 31 (G2 IN). (At this time, be sure to connect a 10kΩ resistor to Vcc as a load for Pins 30 and 31.) The color killer is activated when the burst level falls –36dB or more below the specified input. The SECAM signal (specified input: R-YID: 215mVp-p, B-YID: 167mVp-p) passes through an ACC, bell filter, limiter amplifier, demodulation circuit, line blanking circuit, and de-emphasis circuit to form the color difference signals R-Y and B-Y. After being processed by 1HDL the signals are input to the RGB signal processing circuit. In addition, the color system (PAL, NTSC or SECAM) and sub-carrier frequency (4.43MHz or 3.58MHz) are automatically identified according to the input chroma signal. Circuits such as the internal VCO, demodulation circuit and color axis circuit of the RGB signal processing block (described below) are automatically adjusted. The system is selected either automatically by the I2C bus (COL SYSTEM and X'TAL) or by forcible modes. The color system status selected using the status registers NTSC/PAL, SECAM and X'TAL ID is output (refer to the color status table).
6) RGB signal processing
The Y and color difference signals obtained by the Y/C signal processing circuit are first input to the YUV SW, then selected and switched with the external Y and color difference signals. After the selected Y and color difference signals are used to form the G-Y signal in the next axis circuit (including color control), they are used for the RGB signals. Next, these signals pass through the external RGB signal SW circuits YS1 SW and YM SW (half-tone SW), external RGB signal SW circuit YS2 SW, dynamic color, picture control, gamma correction, clamp, brightness control, drive control, and cutoff control circuits, and are then output on Pin 22 (ROUT), Pin 23 (GOUT), and Pin 24 (BOUT). An external RGB signal (100 IRE 100% white: 0.7Vp-p) conforming to normal video signal specifications is input to Pins 26, 27 and 28 and Pins 30, 31 and 32. The voltage added to Pin 3 (ABL IN) is compared to the reference voltage within the IC and then integrated by the capacitor connected to Pin 42 (ABL FIL) to form a control signal used for picture control and brightness control. The ABL mode can be selected using the register ABL MODE for switching such that only picture control is performed or so that both picture control and brightness control are performed. There is a protective function such that brightness control is activated even when only picture control is being performed if beam current flows excessively.
This IC includes two functions for performing white balance and black balance adjustments: drive control for performing gain adjustment between RGB outputs and cutoff control for performing DC level adjustments between RGB outputs. These can be independently controlled for three channels by the I2C bus. In addition to this, the cutoff control function also includes an auto-cutoff function (AKB) which performs automatic adjustment by forming a loop between the IC and CRT. This can compensate for temporal variations of the CRT.

Auto-cutoff functions are as follows.
• R, G, and B reference pulses for auto cutoff, 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 RGB cathode current (IK) is input to Pin 21 (IK IN).
• The cathode current input to Pin 21 (IK IN) is converted to a voltage within the IC. The reference pulse
interval of this voltage is compared with the reference voltage within the IC, and a current generated by this voltage difference is used to charge a capacitor within the IC. This charge is held at times other than the reference pulse interval.
• The DC level of the RGB output changes according to the voltage generated by the capacitor. A loop functions to make the voltage converted from the current input to Pin 21 (IK IN) match the reference voltage within the IC.
The IC internal reference voltages for R, G and B undergo cutoff control by the I2C bus and can be independently adjusted. The cathode signal current flowing during the reference pulse interval should be about 13µA at the cutoff control center. The IC can also handle up to 100µA cathode leak current flowing during blanking. Large current flows during the video interval, and this leads to destruction around IK IN, be absolutely sure to connect a zener diode of about 4V to the IK IN pin.

4. Notes on Operation
Because the R, G and B signals and deflection signals output from the CXA2060BS are DC direct connected, the pattern (set board) must be designed with 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 by-pass capacitor which is inserted between the power supply and GND as near to the pin as possible. Also, locate the crystal oscillator and IREF resistor as near to the pin as possible, and be sure that signal lines do not pass close to these pins. 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. Use a resistor (such as a meal film resistor) with an error of less than 1% for the IREF pin. Be sure that Vcc1 and Vcc2 have the same electric potential. Use crystals manufactured by Daishinku Corp. Properties of this IC are not guaranteed if used with crystals from another manufacturer.
