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.
