Frequency control specialist Euroquartz has launched a new range of clock oscillators from Statek offering tight frequency stability of ±20 parts per-million (ppm) over the military temperature range and ±10ppm for industrial applications.
Available in frequencies from 10MHz to 55MHz, the new STXO range also offers low root-mean-square (RMS) jitter and low phase noise.
State-of-the-art design, process, manufacturing and test capabilities have made the development of this ultra-miniature 3.2mm x 2.5mm STXO oscillator possible. Key performance capabilities include low RMS jitter typically less than 300 femtoseconds (fs), typical noise floor less than −161dBc/Hz, high-shock survival options (more than 20,000g) and ultra-low Allan Deviation and period jitter (1.4 picoseconds [ps] RMS).
Supply voltage options are 2.5V and 3.3V ±10% with low current consumption of 3.0 milliamps (mA) (no load across temperature range). Offering 15 picofarads (pF) complementary metal-oxide semiconductor (CMOS) output load with enable / disable and tri-state functions, the new Statek STXO range delivers fundamental frequency output with no PLL artefacts and is housed in a hermetically sealed, ceramic four-pad surface mount package.
Offered in versions for industrial applications more than −10°C to 85°C and military applications more than −55°C to 125°C, the new STXO clock oscillators are available with full military testing per MIL PRF 55310 on request. Tighter frequency stability performance can also be provided for special order.
Additional specifications include a start-up time of five milliseconds (ms) maximum, rise / fall time of five newton-seconds (ns) maximum, duty cycle of 45% minimum / 55% maximum and low ageing of 2ppm in the first year.
Defence and aerospace applications include smart munitions, communications, guidance and navigation.
