NOTES: Absolute maximum rating indicates the limit beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the electrical characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. 3. VCC supply pins 6, and 25 must be externally wired together to prevent internal damage during VCC power on/off cycles. 4. The supply current specified is the quiescent current for VCC1/VCC2 and VCC3 with RL = , The supply current for VCC2 (pin 25) also depends on the output load. 5. Output voltage is dependent on load resistor. Test circuit uses RL = 390 6. Measure gain difference between any two amplifiers Vin = 560mVpp. 7. When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit board without socket is recommended. Video amplifier 10MHz isolation test also requires this printed circuit board. The reason for a double sided full ground plane PCB is that large measurement variations occur in single sided PCBs. 8. Adjust input frequency from 10MHz (AV max reference level) to the-3dB frequency (f -3dB). 9. Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation. Terminate the undriven amplifier inputs to simulate generator loading. Repeat test at fin = 10MHz for Iso_10MHz. 10. A minimum pulse width of 200 ns is guaranteed for a horizontal line of 15kHz. This limit is guaranteed by design. if a lower line rate is used a longer clamp pulse may be required. 11. During the AC test the 4V DC level is the center voltage of the AC output signal. For example. If the output is 4Vpp the signal will swing between 2V DC and 6V DC. 12. These parameters are not tested on each product which is controlled by an internal qualification procedure. 1. 2.

OSD INTENSITY INPUT (ACTIVE: HIGH) This input pin is used to indicate the OSD color intensity. Thus, 15 color selection is achievable by combining this intensity pin input with R/G/B OSD input. If you do not want OSD intensity function, you have to connect this pin to ground. If this pin is in high state (normally 5V), the level of OSD output will be attenuated to 50% of original OSD output. The family of samsung OSD IC supports the OSD intensity output function. OSD INPUTS The S1D2518X01 includes all the circuitry necessary to mix OSD signals into the R/G/B video signal. You need 4 pins for function. (R/G/B OSD, OSD blanking) DATA TRANSFER All bytes are sent MSB (Most Significant Bit) bit first and the write data transfer is closed by a stop. The MCU can write data into the S1D2518X01 registers. To do that, after a start, the MCU must send: * * * * The I2C address slave byte with a low level for R/W bit (bit1) The byte of the internal register address where the MCU wants to write data (sub address) The data Stop

APPLICATION POINT
12V Power Routing Because S1D2518X01 is a wideband AMP of above 150MHz, 12V power significantly affects the video characteristics. The effects from the inductance and capacitance are different for each board, and , therefore, some tuning is required to obtain the optimum performance. The output power, VCC2, must be separated from VCC1 using a bead or a coil, which is parallel-connected to the damping resistor. In the case of using a coil , the appropriate coil value is between 0.1uH to 100uH. Parallel-connected a variable resistor to the coil and control its resistance to obtain the optimum video waveform. (Bead use: Refer to Application Circuit ) (Moreover, bead can be replaced using a coil and variable resistor to obtain the optimum video waveform.) VCC1 12V Power Use a 104 capacitor and large capacitor for the power filter capacitor. 12V Output Stage Power VCC2 Do not use the power filter capacitor or use a capacitor smaller than 22pF, because it is an important factor of video oscillation. The coil, resistor and by-pass capacitor for 27 pin B+ must be placed as close as possible to the Vcc2 pin. Output Stage GND2 Care must be taken during routing because it ,as an AMP output stage GND, is an important factor of video oscillation. R/G/B clamp cap and R/G/B load resistor must be placed as close as possible to the GND2 pin. GND2 must be arranged so that it has the minimum GND loop. R/G/B Clamp Capacitor Use the 104 capacitor for normal R/G/B clamps. During the clamp signal's input period, the clamp stage compares the video output's pedestal level and the level adjusted by sub address 01. If an error is detected, current is charged/discharged to the clamp capacitor, so that the video output pedestal level is set to the adjusted level. The current charged/discharged to the clamp cap is about 750uA. The capacitor value is very important. If the R/G/B clamp cap's charge current is different for each channel, the screen can first appear to be red or blue, then later become normal when you turn the power on. In that case, it is best to change the clamp cap value to adjust the charge/discharge time. DC Coupling Capacitor Select the video input DC coupling cap with sagging in mind. Select from between 10uF and 0.1uF.

S1D2518X01
Preliminary I2C BUS CONTROLLED R/G/B VIDEO AMPLIFIER FOR MONITORS
Clamp Pulse The clamp pulse receives its input from the U-Processor and needs a minimum pulse width of 200ns. An active low signal with a pulse width of 500 to 700ns is recommended. But you can change the clamp pulse polarity using CPS bit. If the clamp signal is high during mode change, gm2's clamp operation does not occur. A charge or discharge occurs in the output clamp cap, caused by the transistor's leakage component. This results in a change in the clamp cap's voltage, which can influence the brightness of the screen. Therefore, it is best to supply a low level clamp signal or a pseudo clamp signal during a transient period like that of mode change. Cut-Off Control and Cut-off Brightness Control (RCT, GCT, and BCT pins Applications) This feature, which is an external application for most other products, is built into the IC in S1D2518X. It controls the CRT bias voltage of each R/G/B channel to adjust the raster white balance. Also set brightness can be controlled through the same pins. If the set brightness control is not done at G1, the cut-off brightness control is very useful. Three DACs are needed.

IBRT is the cut-off brightness current which simultaneously controls 3 channels. Its range is 0 - 200uA. ICS is an offset current which simultaneously controls 3 channels through the combination of 2-bit. Its range is 0, 90, 170, and 260uA. ICT is a cut-off control which can control from 0 - 500uA per channel. ICT and ICS currents are used in white balance adjustment. IBRT and ICS currents are used when controlling brightness in the set. ICTX = ICT + ICS + IBRT (0 - 500uA) + (0 - 260uA) + (0 - 200uA) (0 - 960uA) - R.G.B Cut-off control (Raster white balance control) Maximum control current by cut-off register (8 bits): 500A 1-bit control current: 1.96A When you use 75V - 80V for cut-off stage Vcc, CS2, CS1 bit status of S1D2518X should be selected by 0. If these data selects 1, the offset current of the cut-off control will be increased to 260A. Therefore, these data (CS2, CS1) need to be set to 0. But if Vcc for the cut-off stage increases to something like 220V, you need to change the data to 1 by the set status. - Cut-off Brightness Control (Set brightness control) This function is to adjust the brightness. It is composed of 8 bits. Sub address is 06. Maximum control current is 200A (0.78A/1bit). By adjusting this sub address, you can handle the set brightness. This adjustment simultaneously moves one point of the cut-off DC to R/G/B

R/G/B cut-off control and cut-off brightness control are carried out through the same route. The amount of the voltage drop is the product of the sinking current amount of S1D2518X's pin17 and the R1 value. Therefore, the B point's voltage is 80V - (sinking current x R1) + 2Vbe. If the value of R1 is large, the Resolution quality is lessened, but the voltage control range is increased. Since the routes of the cut-off control current and the cut-off brightness control current are the same, the sinking current amount and R1 value should be adjusted for appropriate values to the set's specifications. - Cut-off and Set Brightness Control Method You can use two methods for cut-off and set brightness control. The RCT, GCT and BCT pins are composed of open collector type. The pin configuration is like that.
0.2k
The first method is using current DAC configuration. In this method, sunk current amounts decide cut-off voltage. You used 75V, 75k and 500uA sunk current in the application circuit. Then the cut-off bias voltage is 75V - (75k x 500uA) + 2Vbe = 39V. If you reduce the resistor R1 value or sunk current, then the cut-off bias voltage level goes high. (39V )

When using 10k pull-up resistor, you can get the 5V output range. But, the 5V range include cut-off bright range. So, if you set 1V bright range, you must consider 1.3 - 5V cut-off range for white balance.

ABL The ABL detects the amount of current flowing into the CRT cathode to lower the brightness of the screen. The S1D2518X uses the ABL pin's feedback voltage to control the contrast. The lower the ABL input voltage, weaker the video signal. When open, the ABL is floated to 12V and doesn't operated. When S1D2518X's ABL function is not being used, the ABL pin is connected to a cap in a series to connect to the GND. Ripple extract capacitor must be used. It's value depends on the set characteristics, but normally it uses 1uF 10uF/16V.

Video/OSD Half Tone This feature allows you to handle the OSD character information in a special way that reduces stress on your eyes even for a static screen, and significantly lessens the influence of the character information on the image signals. These effects result in facilitating the relaying of information to you. - Half tone: Loads half of the video and OSD signal gain to the OSD raster to emphasize the OSD characters and the raster.
