Ultra compact crystal unit for automotive applications

September 30, 2013 // By Graham Prophet
Murata has added to its XRC family of hybrid crystal timing device specifically for automotive applications. The new products are approximately 40% smaller than the industry norm and measure 2.5 x 2.0 mm.

The XRC series is available with nominal frequencies in the range of 12 - 24 MHz, and provide a highly accurate high quality clock that is required for automotive electronic control units (ECUs). Typically used for in-vehicle networks such as CAN and FlexRay, the XRC series incorporates a crystal element within a ceramic resonator package structure.

Frequency tolerance is typically ± 100 ppm at 25C. Operating temperature range is -40 to +125C. The ESR is 30-50% lower than similar devices available currently on the market in spite of the small package. This timing device has been developed in conjunction with Murata's new wholly owned subsidiary TEW.
