Multimedia ICs 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.
