SiTime Corporation announced a 32 kHz MEMS Super-TCXO® that sets a new performance benchmark for timekeeping components in electronics. The SiT7910 is part of the SiTime Endura™ ruggedized family for aerospace and defense applications. Devices that use global positioning system (GPS) signals, such as ruggedized handheld radios, ground vehicles and sensors, can acquire and lock to GPS more quickly and securely with the 25x higher precision of this Super-TCXO.

Key features of the Endura SiT7910 Super-TCXO: 32.768 kHz frequency; ±0.2 ppm frequency stability over -55°C to +105°C temperature range, up to 25x better than legacy quartz technology. The device maintains 1 second of accuracy for one year, vs. legacy quartz devices that can only maintain it for one to 14 days.

Best-in-class 20 ppb/g g-sensitivity for resilience in high-vibration environments; Ultra-low power consumption, typically 6.0 µA, for use in portable aerospace and defense electronics; ±5 ppm frequency aging over 20 years, maintains device performance over 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; Pb-free, RoHS, and REACH compliant; Endura enhanced screening flow for high quality and reliability. Availability: The SiT7910 is sampling now. Contact SiTime for order information.

Volume production for the Endura SiT7910 is expected in second quarter, 2023. Upon release, all Endura precision timing solutions will be available on the SiTimeDirect™ store for shipment in as fast as 48 hours.
