Frequency control specialist, Euroquartz has launched a new range of oscillators from Statek Inc. offering ultra-low power, fast start-up and high shock resistance characteristics in a surface-mount package measuring just 3.2 x 1.5 x 0.95mm.
The CXOLHG features frequency output of 32.768kHz and achieves typical low power consumption of 1µA at 3.3V supply voltage. This is comparable with a tuning fork design while fast start-up time of 3ms typical and tight frequency stability are as good as those obtainable with AT-cut crystal designs. The new oscillator is also capable of withstanding shock up to 30,000g and above, significantly higher than that achieved by tuning fork designs.
With full military testing available, Statek’s new CXOLHG oscillator also offers low acceleration sensitivity, typically 0.5ppb/g, essential in aerospace applications.
Specifications include supply voltage range from 1.8 to 3.3V, calibration tolerance of ±25ppm, output load (CMOS) of 15pF and ageing of ±3ppm in first year. Frequency stability is ±10 to ±50ppm over commercial temperature range (0 to +70°C), ±20 to ±50ppm over industrial temperature range from -40 to +85°C, and ±35 to ±50ppm over military temperature range from -55 to +125°C. Shock options encompass 30,000, 50,000, 75,000 and 100,000g (0.3ms, ½ sine) while vibration survival is 20g, 10 to 2000Hz, swept sine.
The new oscillators are hermetically sealed in 4-pad housings and not sensitive to moisture. Maximum process temperature is 260°C for 20 seconds. There are two Enable/Disable options available: E which stops oscillation when the output is put into the high Z state and N which does not have enable/disable pad connected internally.
The new Statek CXOLHG oscillators are available either in tray packs (up to 250 pieces) or 12mm tape and 178 or 330mm reels (EIA418) for more than 250 pieces.
