High-performance 6-channel video driver
IC for progressive DVD
BH7862FS
BH7862FS is a 6-channel video driver IC developed for progressive 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.

Features
1) Each high-performance filter, 6dB amplifier, and 75
driver for DVD are incorporated into a single chip.
2) Driver 6ch (Y, C, MIX, and PY, Pb, Pr for progressive)
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
6) Built-in mute circuit
