TECHNICAL NOTE

High-performance Clock Generator Series

3ch Clock Generator

for Digital Cameras

BU2394KN,BU2396KN

●Description

These clock generators are an IC generating three types of clocks – CCD, USB, and VIDEO clocks – necessary for digital

still camera systems and digital video camera systems, with a single chip through making use of the PLL technology.

Generating these clocks with a single chip allows for the simplification of clock system, little space occupancy, reduction in

the number of components used for mobile camera equipment, which is becoming increasingly downsized and less costly.

●Features

1) Connecting a crystal oscillator generates multiple clock signals with a built-in PLL.

2) The CCD clock provides switching selection outputs.

3) Providing the output of low period-jitter clock.

4) Incorporating compact package VQFN20 most suited for mobile devices.

5) Single power supply of 3.3 V
