Low Earth Orbit (LEO) Quartz Oscillators

Radiation-Tolerant Oscillators for New Space

The need for economically priced oscillators for LEO applications presents a challenge for high-reliability designs. It is important to balance the need for reliability, cost and performance for oscillators in LEO environments.

To meet these requirements, we have taken oscillator designs that have proven track records for performance, yields and design margins and improved them to handle Total Ionized Dose (TID) and single event latch-up levels anticipated for LEO environments. This approach has resulted in our L series portfolio of robust oscillators that can meet the LEO requirements for mission life, launch conditions, radiation tolerance and lower cost.

Featured Products

LX-820 XO

Radiation-Tolerant Small Size

The LX-820 is a 3.2 mm x 2.5 mm quartz oscillator qualified to 50 krad for Total Ionizing Dose (TID) and 40 MeV-cm²/mg for Single Event Latchup (SEL), making it well-suited for small form factor LEO missions.
