Clock generator for PD
BU2190F
The BU2190F is a clock generator IC for PD system drives, and uses a single crystal resonator to generate the three
clock signals needed for PD system drives.
•
Applications
PD system
•
Features
1) Clock signals of three different frequencies can be
generated with a single attached crystal resonator.
2) Internal PLL loop filter, eliminating the need for an
attached loop.
3) Single 5.0V power supply.
4) SOP 8-pin package.
