BU2385KN

Multimedia ICs BU2385KN 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. zApplications Digital still camera zFeatures 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 components.
