3ch Programmable Clock Generator  
Generate  
3 application clocks  
No.09004EAT01  
BU7331EKN  
Description  
The BU7331EKN integrates a 3ch PLL.The frequency of each PLL can be set via serial interface control, making it  
compatible with a wide range of digital applications.  
In addition, sudden frequency changes are handled via rewriting through the register, and BU7331EKN is suitable for sets  
with different frequencies, resulting in more efficient parts management and shorter development time.  
Features  
1) To generate clocks by connecting reference 5.0MHz 48.0MHz.  
2) 5.0MHz75.0MHz output frequency range.  
3) All settings and operation controlled via 2-wire serial interface  
4) Individual level shifter attached to each output  
5) HQFN20V package  
Application  
General digital product of mobile phone, DSC, DVD-player etc.
