BU2192F
The BU2192F is a clock generator IC for personal computers, and uses a single crystal resonator to generate the
three clock signals needed for personal computers.
•^Applications
Personal computers
•^Features
1) Clock signals of two different types can be generat-
ed with a single attached crystal generator.
2) Internal PLL loop filter, eliminating the need for an
attached component.
3) Single 5V power supply.
4) SOP 8-pin package.
