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.

∗ An operation is not guaranteed.
∗ In case it is used at Ta=25 C or more, 5.3mW is reduced at every 1 C.
∗ Radiation resistance design is not used.
∗ Power dissipation is measured when BU2385KN is placed in the board.
