Clock Generator
for Audio/Video Equipment
BU2362FV
General Description
BU2362FV 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 AUDIO clock is a
DVD-Video reference and yet achieves high C/N
characteristics that have low level of distortion factor.
Features
■ Connecting a crystal oscillator generates multiple
clock signals from a built-in PLL circuit.
■ AUDIO clock of high C/N characteristics providing
a low level of distortion factor
■ The AUDIO clock provides switching selection
outputs.
■ Single power supply of 3.3V
Applications
DVD players
