Q-Tech Corp. has announced the introduction of its QT6xxLW line of high-performance, multiple-output oscillators for space, military, avionics, and high-temperature applications. The MIL-PRF-55310 oscillators are Type 1 Class 2 hybrids which are supplied with 1 to 12 low-voltage-differential-signaling (LVDS) output pairs at frequencies from 15 to 200 MHz. The sources can be housed in a choice of two packages, depending upon the number of differential output pairs: a 20-pin flatpack housing measuring 0.625 × 0.625 in. for oscillators with one to six output pairs and a 62-pin flatpack measuring 1.25 × 1.65 in. for sources with eight or more output pairs. Terminals can be finished with gold or hot solder dip. The oscillators operate from a single +3.3-V dc supply and are designed for an operating temperature range of −55 to +125°C. All oscillators are screened to MIL-PRF-38534, Class K modified standards.
For long-term space and defense applications, the LVDS oscillators include 100 krad (Si) total dose ionization radiation hardening and feature better than 1 ps phase jitter at offsets from 12 kHz to 20 MHz from the carrier. The skew between the differential outputs is less than 0.4 ns. “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.”
