Programmable Clock Generator Optimises PCB Space

ROHM’s BU7331EKN is a three-channel programmable Phase-Locked Loop (PLL) clock generator which integrates three clocks on a single chip.

This provides a space-saving and optimised solution for digital applications that require multiple clocks.

Each programmable clock can be set arbitrarily via a serial interface. High-precision operation eliminates the interference effects of other clocks. The frequency of each PLL can be set via the serial interface control, making it compatible with a wide range of digital applications. In addition, sudden frequency changes are handled by rewriting the register.

 

FEATURES Three clocks integrated into a single chip Programmable clock frequencies 3.6mW-per-channel power consumption Pin layout designed to eliminate high-frequency noise Fully-synchronised clocks Built-in level shifter Compact package

APPLICATIONS Surveillance equipment Vending machines Measurement equipment Audio-video systems
