Why Customers Choose Murata's CERALOCK

Usefulness that comes with a simple design

Compact, low-profile and a built-in capacitance design makes it possible to reduce the number of components used.

Frequency accuracy optimized for CAN communication

LS-CAN total frequency tolerance : ±0.8% *1
HS-CAN total frequency tolerance : ±0.27%
CAN-FD total frequency tolerance : ±0.23%
*1：Total frequency tolerance varies by product series.

Quick rise times

Generally “Oscillation start up time” of CERALOCK is more than 10 times faster than conventional crystal.
