Clock generator for personal

computers

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.

Personal computers

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.
