Clock generator
BU2185F
This IC generates the different clock used for DVD. Generates clocks for CD use, sound use, and MPEG use.
Applications • DVD players Features • 1) By connecting a crystal oscillating element, the different clock signals are generated. 2) Enables selection of the reference clock directly or with 1 / 2 output.
3) SOP 16-pin package. 4) Single 3.3V power supply. 5) With the standard clock output, an independent 5V power supply can be applied for a 5V output.
