TECHNICAL NOTE
High-performance Clock Generator Series
DVD-video Reference
Clock Generators
for Audio/Video Equipments
BU2280FV, BU2288FV, BU2360FV, BU2362FV
●Description
These clock generators are an IC generating three types of clocks - VIDEO, AUIDIO and SYSTEM clocks – necessary for
DVD player systems, with a single chip through making use of the PLL technology. Particularly, the AUDIO clock is a
DVD-Video reference and yet achieves high C/N characteristics to provide a low level of distortion factor.
●Features
1) Connecting a crystal oscillator generates multiple clock signals with a built-in PLL.
2) AUDIO clock of high C/N characteristics providing a low level of distortion factor
3) The AUDIO clock provides switching selection outputs.
4) Single power supply of 3.3 V
●Applications
DVD players
