BU2285FV_08 Datasheet, PDF (1/17 Pages) Rohm – DVD-Audio Reference Clock Generator for Audio/Video Appliance

TECHNICAL NOTE
High-performance Clock Generator Series
DVD-Audio Reference
Clock Generator
for Audio/Video Appliance
BU2285FV,BU2363FV
●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 VIDEO clock is a
DVD-Audio reference and yet achieves high C/N characteristics necessary to provide high definition images.
●Features
1) Connecting a crystal oscillator generates multiple clock signals with a built-in PLL.
2) The AUDIO clock provides switching selection outputs
3) The VIDEO clock achieves high C/N characteristics.
4) Single power supply of 3.3 V
