Clock oscillators screened to 100krad for space applications

New Products |
Precision Devices unveiled the flat pack Series XO clock oscillators, using premium swept quartz crystal in a 4-point mount blank. The clock oscillators are now screened to 100krad Total Ionized Dose (TID), which means that they are verified to handle the radiation they will endure in space.

The parts were tested in a proton beam of 64MeV in steps of 25krad until the total dose (TID) was 100krad. The oscillators are designed for low- to mid-orbit applications as standard, and other applications are available on request. The clock oscillators are available in a wide frequency range from 750kHz to 800MHz. Frequency stability is as low as 25ppm. Four output options are available: CMOS, LVDS, LVCMOS and LVPECL.

For maximum flexibility, the devices are available in flat pack packages with 14, 16, 20 or 24 pins. The company also offers a fully customized self-build part number to enable customers to specify the ideal device for their particular application. The oscillators have a wide ambient operating temperature range from -40°C to +85°C, with a storage temperature range of -65°C to +150°C. They are MIL-PRF-38534 and MIL-PRF-55310/QPL certified.
