OVEN CONTROLLED CRYSTAL OSCILLATORS
QEO SC - SC standard series
SC STANDARD SERIES
QEO SC
The SC-cut standard OCXO series is provided in
various package sizes with very high stability
and low ageing rates. With almost 15 years of
SC-cut crystal knowledge in design and
manufacture, the performance of our resonators
offer the best stability for applications requiring
OCXOs. Low phase noise (-160 to -165 dBc/Hz at
floor) can be achieved with our SC-cut design.
Our crystal manufacturing process includes
clean room, high temperature dynamic preageing and 100% testing of crystal parameters.
