Next, measure the output voltages y1 to y10 which correspond to the input voltages a1 to a10 using SG9 as the
input signal.
Select the two points where | yn – yn – 1 | (n = 2 to 10) is a maximum, and label these points yh and yh – 1. Also,
label the input voltages which correspond to yh and yh – 1 as ah and ah – 1, respectively.
From the above:
Maximum gain GM = (yk – yk – 1)/(ak – ak – 1)
Minimum gain GN = (yh – yh – 1)/(ah – ah – 1)
The black side gamma gain is defined as the ratio of the maximum gain to the minimum gain. In other words:
Gamma gain = 20 log (GM/GN)
The gamma breakpoint is defined as the intersection between the straight line passing through points (ak, yk)
and (ak – 1, yk – 1) and the straight line passing through points (ah, yh) and (ah – 1, yh – 1). In other words:
Gamma breakpoint = (GM ∗ GN ∗ (ak – ah) – GN ∗ yk + GM ∗ yh)/(GM – GN)

Description of Operation
Reference signal
The reference level is inserted into the RGB signal by inputting the XCLP2 signal shown below during the RGB
input signal pedestal level interval. Gamma compensation and clamping operation are performed based on this
level.

Bright adjustment
The position of the RGB signal relative to the reference level changes according to the voltage applied to RGB
MBRT (Pin 1). Bright can be controlled without changing the γ characteristics to the panel because the input
bias is changed with the breakpoint for output kept constant.

Gamma compensation
The gamma compensation curve establishes the gain change points (breakpoints) on both the black and white
sides from the reference level. The black and white side gains and the black and white side gain change points
can each be adjusted independently.

Sample-and-hold, gain control and pedestal clamp
Since sample-and-hold circuits are established in the R, G and B lines and each of these circuits is operated
by an independent pulse, the delay can be set freely. In addition, the pulse leak is canceled by establishing a
sample-and-hold circuit in the clamp loop and inputting the differential input of the gain control circuit.

SID output
The CXA1853Q outputs a side black signal for 4:3/16:9 aspect conversion. The black level is adjusted by the
SID CTR pin. In addition, the PRG level can be set in part of the side black signal by inputting the PRG pulse.
The PRG level is adjusted by the PRG CTR pin. The relationship between each input and output is as shown
in the figure below.

Signal center control
The RGB and SID output center voltages are adjusted by the SIG CENT CTR (Pin 37).
When SIG CENT CTR is preset, the output pin center voltage goes to VCC2/2.
Output clamp
The average value of each RGB and SID output signal is detected with external RC circuits and input to the
RGB CLP and SID CLP pins. Then the center voltage offsets among R, G, B and SID outputs are reduced by
feedback which equalizes these detected values and the signal center voltage set by the SIG CENT CTR pin.

CXA1853Q
Notes on Operation
1) R IN (Pin 9), G IN (Pin 10), B IN (Pin 11) input signal impedance
An external capacitor is used as the hold capacitor for the clamp at the input of this IC. Therefore, the input
signal impedance must be sufficiently low (75Ω or less) and the external capacitor must have a small leak
current.
2) Clamp hold capacitors (Pins 51 to 53 and 65 to 67)
The external capacitors connected to these pins must have a small leak current.
3) R, G, B, SID OUT load capacitance
The output signal will tend to oscillate if the R, G, B and SID OUT load capacitance increases. Be sure to
insert a 100 to 220Ω resistor in series to these output pins, and design to keep the load capacitance from
exceeding 30pF.
4) External capacitor at the output
The leak current absolute value and tolerance for the R, G, B and SID OUT average value detecting
capacitors should be small.
Note that if there is an offset in the leak current between R, G and B, offset voltage is also generated
between R, G and B in the external resistor, which causes a DC offset of the output signal.

5) GND and power supply pins
Pins 12, 22, 34, 48, 55 and 64 (GND) should be set to the minimum identical potential applied to the IC,
and should not be left open. In addition, the potential at Pins 8, 18, 50 and 62 should be the same.
