Semiconductors Product of the Year
Product Name: XCalibur
SiTime’s XCalibur active resonator is a MEMS solution for the timing industry’s supply chain disruption. This innovative
new product category solves supply chain constraints using programmable semiconductors to deliver a drop-in
replacement for quartz crystal resonators. Additionally, XCalibur provides higher performance and reliability while
reducing development time by up to two months in automotive, enterprise and industrial applications.
The new SiTime XCalibur active resonators solve quartz availability problems through programmability and by using the
semiconductor supply chain that is independent of quartz. Additionally, quartz resonators are notorious for posing
design challenges requiring additional testing and development, delaying customer projects. XCalibur solves these
challenges by providing a more reliable, flexible drop-in replacement that’s much easier to implement.
It is commonly known that quartz resonators have weaknesses such as being susceptible to strong EMI fields and
requiring negative resistance testing in every design and layout cycle, as well as requiring qualification for each
frequency. With SiTime’s XCalibur active resonators, customers no longer experience EMI or start-up issues. SiTime’s
XCalibur eliminates the need to send boards to quartz vendors for negative resistance testing. Furthermore, customers
can implement a new frequency in the same design without re-qualifying the part. All these benefits enable the
customer to get to market faster.
SiTime XCalibur active resonators also provide 10x better reliability than quartz, making them ideal for automotive and
industrial applications that demand robustness and long life in harsh environments. The many benefits of these MEMS-
based resonators also extend to communications and networking, enterprise, consumer electronics, mobile and IoT and
aerospace and defense applications.
The SiTime XCalibur active resonators can replace 4-pin SMD crystal resonators in demanding automotive, industrial and
enterprise equipment applications. They provide excellent stability, greater reliability, reduced BOM and ease of design.
