Murata's hybrid ceramic and quartz crystal resonator combines high precision, small size and low cost

The XRCGA series features a quartz crystal element manufactured by Tokyo Denpa alongside Murata's ceramic resonator technology resulting in smaller and lower cost devices that maintain the precision offered by the crystal.

Murata's production technology results in smaller and lower cost devices that maintain the precision offered by the quartz crystal.

Murata originally developed its ceramic resonator technology, called CERALOCK®, in 1977. Today, CERALOCK® resonators are widely used in consumer electronics for resonating CPU clock signals. This type of ceramic resonator is small and inexpensive. However, the adoption of SATA and USB has accelerated the transfer speed for the PC interface, so resonators used for today's High Speed Peripherals require higher precision than ceramic resonators can provide. To respond to market demands for high precision, small package, low cost resonators for USB applications, Murata has combined Tokyo Denpa's high quality quartz crystal element with its ceramic resonator and production technology to develop the hybrid resonator. In addition to CERALOCK's® stronghold in automotive and consumer applications, Murata now aims to expand its share in the consumer market where relatively high precision is required such as HDD, USB, SSD.

The XRCGA series of hybrid resonators is currently available with nominal frequencies of 30, 33.868, 40 and 48MHz. 25MHz parts are under development. The high precision resonators have initial frequency deviation of ±100 ppm and temperature characteristic of ±50 ppm over the operating temperature range -30 to +85°C. The series is RoHS compliant.
