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.

CERALOCK for vehicle operations

High reliability tailored to individual power train / chassis driving, turning and stopping functionalities.
