Q-Tech has announced the availability of the QT6xxLW Multiple Output LVDS Series of space qualified crystal oscillators. These MIL-PRF-55310 oscillators are Type 1 Class 2 hybrids, delivering exceptional frequency and temperature stability for space satellite and other high-performance aerospace applications. Units in the series are available with from 1 to 12 LVDS differential output pairs at selected frequencies between 15 MHz to 200 MHz.

The Series is offered in two packages, depending on the number output pairs: a 20-pin, .625x.625” flat pack for one to six LVDS pairs and a 62-pin, 1.25x1.65” flat pack for eight to twelve output pairs. Terminal finish options are gold or hot solder dip.

All QT6xxLW Series oscillators operate from a 3.3 Vdc supply voltage. They are rated for operation over a full military -55C to 125C temperature range. All are quality conformance screened to MIL-PRF-38534, Class K modified standards.

Exceptional reliability – an essential requirement for devices in this class – is supported by a combination of industry-leading performance specifications, including: 100 kRad(Si) total dose ionisation radiation hardening, Integrated Phase Jitter (from 12 kHz to 20 MHz) less than 1 ps, Skew between outputs of less than 0.4 ns, and excellent shock and vibration.

“The LVDS output of the QT6xxLW LVDS Series delivers the low phase noise and virtually jitter-free performance required in many satellite and military applications,” said Scott Sentz, Q-Tech’s Director of Sales and Marketing. “The innovative multiple output packaging saves valuable board space and cost.”
