EWOS5500 OCXO Crystal Oscillator
20 MHz Oven Controlled Crystal Oscillator
View all Oven Controlled Crystal Oscillators (OCXOs).
EWOS5500 provides a unprecedent trade-off between global performances and high reliability for large volume space applications. It can be delivered in several thousand units at low price, providing a simultaneously very high frequency stability, accuracy and very low power consumption.
It can be used for GNSS, OBC, ranging or Radio functions within Mini & Microsatellites operating in Low Earth Orbits.
Its ASIC core has been tested against radiations up to 100 krad, and this OCXO is robust against shocks & vibrations. Will be flight proven in 2018.
