VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS
VIDEO AMP MERGED OSD PROCESSOR
The S1D2514X01 is a very high frequency video amplifier
& wide range OSD processor 1 chip system with I2C Bus
control used in monitors. It contains 3 matched R/G/B video
amplifiers with OSD processor and provides flexible
interfacing to I2C Bus controlled adjustment systems.

AC ELECTRICAL CHARACTERISTICS
(Tamb = 25 °C, VCC = 12V, VDD = VDDA = 5V, ABL input voltage = 5V, HFLB input signal = S3, load resistors =
470Ω, Vin = 0.7Vpp manually adjust video output pins 18, 21 and 24 to 4V DC for the AC test (see 11) unless
otherwise stated (see 12))
