S1D2503X01-D0B0
I2C BUS CONTROLLED R/G/B VIDEO AMPLIFIER
32-DIP-600A
The S1D2503X01-D0B0 is a very high frequency video amplifier system with I2C bus control used in monitors with high resolution up to 1600 x 1200. It contains 3 matched R/G/B video amplifiers with OSD interface and provides flexible interfacing to I2C bus controlled adjustment systems.
FUNCTIONS
* * * I2C bus controlled 200MHz RGB video pre-amplifier for monitors The S1D2503X01-D0B0 is a very high frequency video amplifier system with OSD interface controlled by I2C bus. All controls and adjustments are digitally performed thanks to I2C bus. : Contrast, brightness and DC output level of R/G/B signals common to the 3-channel and drive adjustment (sub contrast), cut-off control (AC or DC coupling by CT bit) is separated for each channel. The S1D2503X01-D0B0 is included video & OSD half tone function. The white blance adjustment is effective on brightness, video & OSD signals. The S1D2503X01-D0B0 works for application using AC or DC coupled CRT driver. In addition to beam current limitation (ABL), OSD intensity interface and brightness uniformity (BU) interface are possible with external pins.

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 27 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 VDD with RL = , The supply current for VCC2 (pin 27) 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.

FUNCTIONAL DESCRIPTION
OSD INTENSITY INPUT (ACTIVE: HIGH) This input pin is used to indicate the OSD color intensity. Thus, 16 color selection is achievable by combining this intensity pin with R/G/B OSD input. OSD INPUTS The S1D2503X01-D0B0 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 S1D2503X01-D0B0 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
Serial Interface The 2-wires serial interface is an I2C bus interface. The slave address of the S1D2503X01-D0B0 is DC (hexadecimal) Bit8 1 Bit7 1 Bit6 0 Bit5 1 Bit4 1 Bit3 1 Bit2 0 Bit1 0 (W)

REGISTER DESCRIPTION Contrast (OSD contrast adjustment) (8-bits) The contrast adjustment is made by controlling simultaneously the gain of three internal variable gain amplifiers through the I2C bus interface. The contrast adjustment allows you to cover a typical range of 38dB. Brightness Adjustment (8-bits) The brightness adjustment controls to add the same black level (pedestal) to the 3-channel/R/G/B signals after contrast amplifier by I2C bus. Cut-Off Brightness Adjustments (8-bits) The cut-off brightness adjustment is made by simultaneously controlling the external cut-off current. SUB Contrast Adjustment (8-bits x 3) The SUB contrast adjustment allows to cover a typical range of 12dB. Cut-Off Adjustments (8-bits x 3) These adjustments are used to adjust the white balance, and the gain of each channel is controlled by I2C bus.

RECOMMENDATION
12V Power Routing Because S1D2503X01-D0B0 is a wideband AMP of above 200MHz, 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 20uH - 200uH. 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. 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. Brightness Uniformity(modulation means suppressing the ratio to the video output level) The brightness uniformity feature using the Pre AMP directly influences the video signal, so it can influence the focus as well. Therefore, it is best to minimize the modulation degree as much as possible. Try not to go above10%. When not using the IC's B/U feature, connect it to a capacitor of about 0.1uF and short it to GND.
