BU2385KN
BU2385KN is Clock generator for digital still camera manufactured by ROHM.
feature
. Clocks can be easily changed for other applications. The internal dividing control allows the frequency to be switched outside. z Applications Digital still camera z Features 1) Multiple frequency clock signals can be generated by the built-in 3-channel PLL through connecting crystal oscillator. 2) QFN20V package 3) 3.3V single power supply 4) For crystal 14.318182MHz
- 28.636363MHz 5) No need additional ponents. (BU2385KN have PLL loop filter in side). z External dimensions (Unit : mm)
