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.
