High-performance Clock Generator Series
Compact 1ch Clock Generators
for Digital Cameras
BU3071HFV,BU3072HFV,BU3073HFV,BU3076HFV,BU7322HFV,BU7325HFV
●Description
These Clock Generators incorporates compact package compared to oscillators, which provides the generation of
high-frequency CCD, USB, VIDEO clocks necessary for digital still cameras and digital video cameras.
●Features
1) SEL pin allowing for the selection of frequencies
2) Selection of OE pin enabling Power-down function
3) Crystal-oscillator-level clock precision with high C/N characteristics and low jitter
4) Micro miniature HVSOF6 Package incorporated
5) Single power supply of 3.3 V
●Applications
Digital Still Camera, Digital Video Camera, and others
