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.
