I2C BUS CONTROLLED R/G/B VIDEO AMPLIFIER FOR MONITORS S1D2503X01-D0B0

I2C BUS CONTROLLED R/G/B VIDEO AMPLIFIER

32-DIP-600A

The S1D2503X01-D0B0 is a very high frequency video amplifier
system with I2C 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 I2C bus controlled adjustment systems.

FUNCTIONS

• I2C 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 I2C
bus.

• All controls and adjustments are digitally performed thanks to I2C 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.
