Timing Devices (MEMS Resonator / Crystal Unit / Ceramic Resonator)Crystal Units

Smart Meter Block Diagram

"Ceramic resonators" are used in the displays, ultrasonic flowmeter sensors, and microcomputers equipped in various smart meters (power, gas, heat, waterworks) while crystal units are used in the ICs for wired and wireless communication, and "piezoelectric sounders" are used for data reading check sound devices.

This section introduces "crystal units."
