ETC BU2286FV

01W031A
Clock generator IC
BU2286FV
Description
BU2286FV is an IC that generates multiple clocks
from the built-in 2ch PLL of the external crystal
oscillator used for DVD system. This IC creates
six kinds of signals for video, audio, and low jitter
system.
Dimension (Units : mm)
Features
1) Can generate clock signals needed for DVD by a single chip
2) All output low jitter (No load 30ps)
3) Built-in PLL loop filter, No external components needed
4) 3.3V single power supply
5) Small SSOP-B16 package
