All are available with either sinewave or CMOS logic outputs.
QT2021 is the MCXO series, available in standard frequencies from 10 to 100MHz,
Key features are radiation tolerance to 50kRad(Si) TID, frequency stability over temperature of ±10 to ±30ppb, minimum single event latch-up of 75MeVcm2/mg, acceleration-sensitivity of 1ppb/g for shock and vibration tolerance, and a phase noise floor of -168dBc/Hz at ≥100kHz offset.
Weight is 50g and maximum consumption 90mW.
The OCXOs are called Axiom75Sx and come in frequencies between 10MHz to 400MHz.
These have 50kRad(Si) TID radiation tolerance and frequency stability over temperature of better than ±50ppb. Phase noise floor is -180dBc/Hz at ≥100kHz offset.
These packages are hermetically-sealed.
Find Q-Tech and its space-qualified crystal oscillators at IMS this week on booth 2223.
