High-stability ceramic resonators move up to NFC and USB frequencies

Murata has extended its CERALOCK® ceramic resonators range with the CSTCE-XK series, allowing Near-Field Communications (NFC) and high-speed USB applications to benefit from a lower-cost and smaller-size alternative to quartz crystal resonators.

New members of the CSTCE-XK series include a 27.12MHz device designed specifically for use in NFC systems such as contactless payment and close-proximity file sharing. Other members of the series cover operating frequencies from 24MHz to 48MHz, serving applications such as 480Mbit/s Hi-Speed USB 2.0 communications.

The new devices deliver tight initial frequency tolerance of -250ppm to +200ppm, as well as minimal frequency shift of ±150ppm between 0°C and 70°C for stable and reliable operation. Each of the devices introduced also features built-in load capacitance, to deliver space savings and reduce part count. Available load-capacitance values are 5pF, 10pF and 15pF with ±20% tolerance.
