Datasheet
3ch Clock Generator for Digital Cameras
BU2396KN
General Description
This clock generator IC is produces three types of
clocks for CCD, USB, and VIDEO. These clocks are
necessary for digital still camera systems and digital
video camera systems. These are contained in a
single chip with the use of the PLL technology.
Generating these clocks with a single chip allows for
simplified design of the clock system. It occupies less
space and reduced number of components used for
mobile camera equipment which is increasingly being
downsized and becoming less costly.
Features
 Connecting a crystal oscillator generates multiple
clock signals with a built-in PLL.
 The CCD clock provides switching selection
outputs.
 Providing the output of Low Period-Jitter Clock.
 Uses compact package VQFN20 which makes it
suitable for mobile devices.
 Single power supply of 3.3V
