Wide temperature automotive timing device with exceptional accuracy

Murata Manufacturing Co Ltd unveils a cutting-edge electronic timing device featuring exceptional accuracy ±40ppm and reliability even in wide-temperature conditions -40C to +125C. Managing the limitations of current timing components in automotive electronic systems improves the design and deployment of next-generation IVN, wireless communication, and ADAS functions.

As the automotive industry continues to seek greater integration and electronic downsizing to address the growing number of critical electronic systems, the performance necessities for components are growing. To achieve tighter packaging without compromising accuracy, critical components like timing devices must now have higher temperature limits. There is also a growing demand to incorporate features like BLE and ethernet in vehicles, which demands more accurate timing than what is commonly offered by automotive crystal units.

The company's high-accuracy and high-temperature automotive crystal (HCR), or XRCGE_M_F series, redefines timing component performance and reliability. It sets a new global standard to achieve a total frequency tolerance of ±40ppm throughout an operating temperature range of -40C to +125C. This combination enables automotive engineers to achieve stable and highly accurate timing without system calibration or temperature compensation measures, reducing development efforts and costs.

The company has a long-standing history of being at the forefront of automotive timing solutions, starting with introducing its ceramic resonators in 1997 and then its crystal units in 2015 – HCR is the next step. Through the optimisation of artificial crystal growth, assembly, and inspection, its groundbreaking resin-sealed package technology and crystal design optimise allow HCR to achieve high-temperature operation and high accuracy. This combination is perfectly suited to support the latest vehicle communication and safety functions such as CAN and ethernet IVNs, ADAS components like cameras, LIDAR, and RADAR, as well as wireless communication technologies such as RF, NFC, BLE, ZigbeeTM, and UWB.

"HCR is a true step forward that perfectly aligns with the latest automotive demands," said Munenori Hikita, director of Functional Devices Division at Murata. "With our 'world's first' solution, engineers will be able to deploy downsized designs and high-performance communication circuits without compromise."
