Clock generator for digital still camera

BU2385KN

BU2385KN is a clock generator IC that can generate multiple frequencies (clocks) from one oscillator. Excellent jitter

characteristic is achieved through the built-in high-performance 3-channel PLL. High-quality sound and image equivalent

to the oscillating module are the result of this feature. Clocks can be easily changed for other applications. The internal

dividing control allows the frequency to be switched outside.
