C BUS CONTROLLED R/G/B VIDEO AMPLIFIER
The S1D2503X01-D0B0 is a very high frequency video amplifier
system with I
2
C bus control used in monitors with high resolution up to
1600
1200.
It contains 3 matched R/G/B video amplifiers with OSD interface and
provides flexible interfacing to I
2
C bus controlled adjustment systems.
FUNCTIONS
I
2
C 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 I
2
C
bus.
All controls and adjustments are digitally performed thanks to I
2
C 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:
1.
Absolute maximum rating indicates the limit beyond which damage to the device may occur.
2.
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.
V
CC
supply pins 6, and 27 must be externally wired together to prevent internal damage during V
CC
power on/off
cycles.
4.
The supply current specified is the quiescent current for VCC
1
/VCC
2
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.

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 I
2
C 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)

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.
