C bus controlled 150MHz RGB video pre-amplifier for monitors
The S1D2518X01 is a 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 are separated for each channel.
The S1D2518X01 is included video & OSD half tone function.
The white balance adjustment is effective on brightness, video & OSD signals.
The S1D2518X01 works for application using AC coupled CRT driver.
In addition to beam current limitation (ABL), OSD intensity interface is 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 25 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 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.

FUNCTIONAL DESCRIPTION
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 I

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 I

C BUS CONTROLLED R/G/B VIDEO AMPLIFIER FOR MONITORS

Preliminary
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.
Figure 4. Internal Diagram
It is basically configured as a current mirror.
Cut-off range control through an external pin is decided by the current sinking amount at the RCT/GCT/BCT pins.

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): 500
A
1-bit control current: 1.96
A
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 260
A. 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 200
A (0.78
A/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

Preliminary
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.
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

Refer to typical application circuit.
CS1/CS2: Cut-off control offset current for AC coupling.
CS1 bit = 1: Cut-off control current + 90uA current sunk
CS2 bit = 1: Cut-off control current + 170uA current sunk
CS1 bit = 1, CS2 bit = 1: Cut-off control current + 90uA + 170uA current sunk
If CS1 bit =1, CS2 bit =1, cut-off register = FF, and cut-off brightness register = FF, then 90uA + 170uA + 500uA +
200uA = 960uA current sunk by S1D2518X 17, 18, 19 pins (each channel).

The second method is using generic cut-off control IC.
In second method, you must use pull-up resistor.
Case 1. 5V Pull-up
In above picture, RCT pins outputs 5V - (From 0 to 500uA ) x 10K = from 5V to 0.3V DC level.
So, all kinds of cut-off IC using 0 - 5V input range can be used.

5V - 10K x 500uA = 0.3V

5V - 10K x 200uA = 3V
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.

So, all kinds of cut-off IC using 0 - 5V input range can be used.

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.

Horizontal Blank Pulse
The horizontal blank pulse receives its input from the monitor horizontal scan.
The typical horizontal blank pulse width is 3
S. The pin configuration is like that.
You can use three types of horizontal blank pulse.
The first is the original positive horizontal blank pulse with integration circuit and differentiation circuit.
If you increase the width of horizontal blank pulse, you have to increase C1'S value.
The second is the positive TTL logic signal.
The threshold voltage of the horizontal blank pulse is the 0.7V.
