BU2288FV
The BU2288FV is an IC that generates plural clocks required for DVD system from a 2-channel PLL external crystal
oscillator. The six kinds of signals for video and audio system are generated with low jitter.
zApplication
All DVD sets
zFeatures
1) All clock signals needed for DVD can be
generated by a single chip.
2) All output low jitter (No load 30psec)
3) No need for additional components.
(BU2288FV has a PLL loop filter inside.)
4) 3.3V single power supply
5) Small SSOP-B16 package.

∗ An operation is not guaranteed.
∗ In case it is used at Ta=25°C or more, 4.5mW is reduced at every1°C.
∗ Radiation resistance design is not used.
∗ Power dissipation is measured when BU2288FV is placed on the board.
