Register Description

1. Contrast Adjustment (8-Bits)
The Contrast adustment 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 38 dB.

2. Sub Contrast Adjustments (8-Bits × 3)
These Adustments are used to adjust the gain of each channel controlled by the I2C bus. The Sub Contrast

adjustment allows you to cover a typical range of 12 dB.

13

S1D2504A01 I2C BUS COTROLLED R/G/B VIDEO AMPLIFIER

3. Brightness Adjustment (5-Bits)
The Brightness adjustment controls to add the same black level (pedestal) to the 3-channel R/G/B signals by

I2C bus.

4. Cut-Off Adjustments (8-Bits × 3)
These Adjustments are used to adjust the white balance of the each channel controlled by the I2C bus.

5. Cut-Off Brightness Adjustment (8-Bits)
The Cut-Off Brightness Adjustment controls the 3-channel Cut-Off by I2C bus.

6. Slave Address
The 2-wire serial interface is an I2C BUS interface.

The Slave address of the S1D2504A01 is DCH (hexadecimal)

Bit 8 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1

1 1 0

0 0 (W)

7. 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 S1D2504A01 registers.
To write data into the S1D2504A01, after a start, MCU must send :

- The I2C address slave byte with a low level for R/W bit (bit 1)

- The byte of the internal register address where the MCU wants to write data. (SUB Address)

- The Data sent to slave
