BH7865FS
High-performance 5-channel video driver
IC for DVD
BH7865FS
BH7865FS is a 5-channel video driver IC developed for DVD player/recorder. Special filters adjusted to each band of
various video signals are incorporated into a single chip. Extended definition, size reduction, and high cost performance
can be achieved in DVD players.
zApplication
DVD players, DVD recorders
zFeatures
1) Each high-performance filter, 6dB amplifier, and 75Ω driver for DVD are incorporated into a single chip.
2) Driver 5ch (Y, C, MIX, Cb, Cr)
3) Group delay difference between chroma signal and luminance signal is a small number of nsec.
4) Drive 2 lines of each signal
5) Operating by 5V single power supply

∗1 Add the sine wave of "f=1MHz (C : f=3.58MHz)" to the input VIN and adjust the input level so that the tertiary distortion of output can be -30dB.
Then, the output voltage shall be a maximum output level VOM (VPP).
∗2 Measure the input voltage VIN50 (V) and input open circuit voltage VIN (V) when 50µA has applied to the input CIN, CbIN and CrIN. Then, the input impedance ZIN is as
follows : ZIN=|VIN50−VIN| / 50µ [kΩ]
