FUNCTIONAL 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 I
2
C bus interface.
The contrast adjustment allows 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 I
2
C BUS.
Cut-Off Brightness Adjustments (8-bits)
The Cut-Off Brightness adjustment is made by controlling simultaneously external cut-off current.
Cut-Off(SUB Contrast) Adjustment (8-bits
′
3)
These adjustments are used to adjust the white balance, and the gain of each channel is controlled by I
2
C BUS.
The SUB contrast adjustment allows to cover a typical range of 11dB.
OSD Inputs
The KA2506 includes all the circuitry necessary to mix OSD signals into the R/G/B video signal.
In order to this function needs 4 pins. (R/G/B OSD, OSD blanking)
Serial Interface
The 2-wires serial interface is an I
2
C BUS interface.
The slave address of the KA2506 is DC (in hexadecimal)
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 KA2506 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 interinal register address where the MCU wants to write data (SUB Address)
- The data
