BU2191F
The BU2191F is a clock generator IC for hard disk drives, and uses a single crystal resonator to generate the three
clock signals needed for hard disk drives.
Applications
Hard disk drives
Features
1) Clock signals of three different frequencies can be
generated with a single attached crystal resonator.
2) Internal loop filter, eliminating the need for an at-
tached loop.
3) Single 5.0V power supply.
4) SOP 8-pin package.
