Microchip Adds the LX-820 Quartz Oscillator to its L-Series Timing Portfolio
Microchip Technology has expanded its L-Series of timing devices with the introduction of the LX-820 Radiation-Tolerant Quartz Oscillator. This new component is specifically engineered for demanding Low Earth Orbit (LEO) and other space applications, addressing the critical need for reliable and precise timing in modern satellite systems.
The L-Series portfolio, which includes the LX-820, is strategically positioned between commercial off-the-shelf (COTS) oscillators and traditional high-reliability space-grade products. This unique positioning allows Microchip to combine commercial or military-grade components with rigorous production inspection, electrical and thermal analysis, and hybrid manufacturing processes. The result is a family of oscillators that offers a balance of performance, radiation tolerance, and accessibility.
A key differentiator for the L-Series, including the LX-820, is its ability to alleviate persistent challenges faced by satellite developers: supply chain constraints and budget pressures. Unlike many space-qualified timing solutions that often come with extended lead times and significant procurement costs, the L-Series is designed to provide a more accessible alternative, with many configurations available from stock or with lead times of less than 20 weeks. This approach aims to reduce overall program costs by minimizing the need for extensive component pedigree and documentation typically associated with traditional high-reliability space-grade timing products.
