Clock Generator

for Audio/Video Equipment

BU2280FV

General Description

BU2280FV 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 that have

low level of distortion factor

■

The AUDIO clock provides switching selection

outputs.

■

Single power supply of 3.3 V

Applications

DVD players
