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.
