Clock oscillator certified for space travel

30 April 2008 Electronics Technology

Precision Devices (PDI) has announced the introduction of a newly designed and developed ceramic J-lead crystal clock oscillator. The new J-lead package has been introduced to enable compliance with stringent type approvals.

Development and implementation of an enclosed quartz crystal design has enabled PDI to introduce a new design that compares favourably with existing hybrid IC technology which employs an open crystal blank construction. The new enclosed design provides good crystal ageing characteristics and enhances hermetic performance.

Supporting a frequency range of 750 kHz to 200 MHz, the compact 7,4 x 8,9 mm JL4 J-lead package, available with an operating voltage of 2,5 V or 3,3 V and an operating temperature range up to -55°C to 125°C, makes this clock oscillator suited to high end commercial, aviation, space flight and military applications.

The new oscillator has successfully met the environmental and screening test requirements for Class type S as required for space flight. The test requirements for Class S approval include rigorous random vibration, high frequency sine-vibration, mechanical shock and temperature cycling test profiles. The J-lead package termination method also allows the oscillator to comply with the NASA-STD-8739.3 technical standard which ensures the physical integrity and continuity of solder connections used in flight hardware and mission critical ground support equipment. The J-lead design also exceeds the 5000 G-force acceleration requirement described in many missile and rocket propulsion applications.
