SiTime launches new generation 32 kHz MEMS TCXO

SiTime has announced the release of a 32 kHz MEMS Super TCXO that the company claims sets a new performance benchmark for electronic timing components, with production scheduled for the second quarter.

The device is part of SiTime's Endura family and is intended for aerospace and defense applications.

Devices that use GPS signals, such as ruggedized handheld radios, ground vehicles and sensors, can acquire and lock onto GPS faster and more securely with the 25x higher accuracy of this super-TCXO.

"GPS signals are ubiquitous and a critical component of national security, everyday communications, financial systems, and power grid operations," said Piyush Sevalia, executive vice president. "However, it is susceptible not only to environmental interference, but also to jamming and spoofing. GPS modernization is a multi-year, multi-billion-dollar effort to upgrade the system with better functionality, performance, and security. The tool that enables this modernization is precision timing, ensuring faster and more secure acquisition and lock on to GPS signals, even in the harshest conditions." The SiT7910 TCXO excels at overcoming these challenges. Like other SiTime products, it is another example of using SiTime's MEMS, analog, and system technologies to create precision timing solutions that solve the world's biggest problems today.

feature:

32.768 kHz frequency

±0.2 ppm frequency stability over the -55°C to +105°C temperature range is 25 times better than conventional quartz technology. The device maintains 1 second accuracy for one year, while conventional quartz devices can only maintain this accuracy for 1 to 14 days.

Best-in-class 20 ppb/g sensitivity for flexibility in high vibration environments

Ultra-low power consumption, typically 6.0µA, for portable aerospace and defense electronics

±5 ppm frequency aging for 20 years, maintaining device performance for decades

1.62 V to 3.63 V operating supply voltage range for design flexibility

Small 2.5 x 2.0 mm package for space-constrained applications

Lead-free, RoHS and REACH compliant
