Clock Generator
for Audio/Video Equipment
BU2363FV
General Description
BU2363FV is a clock generator IC capable of
generating three types of clocks - VIDEO, AUDIO and
SYSTEM clocks that are necessary for DVD player
systems. It is a single chip solution that uses PLL
technology. Particularly, the VIDEO clock is a
DVD-Audio reference and yet achieves high C/N
characteristics necessary to provide high definition
images.
Features
Connecting a crystal oscillator generates multiple
clock signals from a built-in PLL circuit.
The AUDIO clock provides switching selection outputs
The VIDEO clock achieves high C/N characteristics.
Single power supply of 3.3 V
Applications
DVD players
