Ceramic resonators tout 'tightest' tolerance

Murata's CSTCE resonators

Aimed at USB 2.0 high-speed applications, Murata Electronics North America said it offers the industry's tightest tolerance500ppmceramic resonators. These CSTCE series resonators provide a smaller 3.2-by-1.3-by-1mm package and less expensive option than similar-sized quartz crystal resonators.

Murata's ceramic processing technology and unique piezoelectric material has led to the development of small and thin ceramic resonators designated as Ceralock including the CSTCE series, which offer high oscillation frequency and tight tolerance. These products are designed for use as a stable timing source for microprocessors.

As a result, the CSTCE ceramic resonator series can compete with a quartz crystal resonator's tight tolerance capabilities. In addition to the improved tight tolerance, reduced footprint and lower cost, ceramic resonators also offer built-in load capacitors (crystals do not), faster rise time, greater shock resistance of standard parts and no "drive level" concerns, said the company. The CSTCE series ceramic resonators are custom frequency correlated to a customer's ICs and PBCs.

The CSTCE series devices are available for the sample price of 48 cents (3,000 per reel). Delivery is from stock to 10 weeks.
