Space Qualified Crystal Oscillators with High Shock Resistance

Q-Tech Corporation has introduced the QT723 and QT735 Series of space qualified crystal oscillators, offering satellite and space craft designers exceptional performance in the industry’s smallest surface-mount packages. These New Space, Low-Earth Orbit (LEO) oscillators are 50 kRad(Si) total dose ionization radiation hardened, high shock (20,000 g) resistant and screened per MIL-PRF-55310, Level B with PIND.

The 2.5 x 3.2 mm QT723 Series offers models with user-prescribed 1.500 to 250 MHz, tri-state CMOS outputs powered by an input voltage of 1.8, 2.5 or 3.3 Vdc. The QT735 Series, in a slightly larger (3.2 x 5.0 mm) package, is offered in CMOS, LVDS and LVPECL versions with input voltages up to 5.0 Vdc and selectable frequencies from 1.000 to 250 MHz.

Q-Tech is a leading supplier of crystal oscillators for space, military, avionics and high temperature applications. These two new series of New Space crystal oscillators are answering the need of aerospace system designers for footprint-saving devices, as they work to pack more functionality into their new LEO systems.

The crystal oscillators are available now with delivery times of 8-10 weeks (Engineering models w/o MIL-PRF screening) and 12-14 weeks (Flight models with MIL-PRF screening).
