SiTime Corporation today announced two new Endura precision timing oscillator families. These ruggedized devices are engineered to deliver high performance in extreme conditions in aerospace-defense applications such as Positioning, Navigation and Timing (PNT), tactical communications, network synchronization and surveillance. The devices include the Endura ultra-stable Super-TCXO® and the Endura low-jitter differential oscillator. Both families deliver 10x better environmental resilience. In addition, the Endura Super-TCXO family delivers up to 5x better stability, while the differential oscillator family delivers the best jitter.
“Timing technology is ever more crucial in aerospace and defense applications where extreme conditions are the norm,” said Fari Assaderaghi, EVP, Technology and Engineering, SiTime. “Today, in these systems, timing is a major source of performance challenges during system verification, qualification, and field operation. This leads to significant engineering time spent in troubleshooting and/or negotiating waivers with end customers. With the drive to higher performance and positioning accuracy, timing requirements for new aerospace-defense electronics are only getting more stringent. It is difficult to foresee how legacy timing devices will continue to perform well in these new systems.”
“SiTime Endura precision timing solutions deliver a dramatically better user experience,” continued Assaderaghi. “Not only can designers count on the performance and reliability of Endura-based timing systems, but they can also save valuable development time that would have otherwise been spent in troubleshooting. The SiTime Endura family is fast becoming the preferred timing choice for aerospace and defense engineers.”
SiTime’s innovative MEMS, analog and systems technologies enable many features that simplify design. For example, frequencies are programmable up to 6 decimal places of accuracy and ensure that the designer can select the exact frequency they want, to enhance system performance. With a frequency stability specification as low as ±10 ppb, designers can replace unreliable, power-hungry, large OCXOs with easy-to-use Super-TCXOs. With an industry-leading power-supply noise rejection (PSNR) specification, SiTime devices are very resistant to power supply noise, which is a common problem in the dense electrical environments of aerospace-defense electronics.
