Frequency control specialist, Euroquartz has announced availability of Statek’s new range of miniature high performance quartz crystal oscillators designed and manufactured for high temperature applications. Offering ultra-low power consumption and high shock resistance characteristics, the new CXOLHT surface mount devices are capable of withstanding temperatures up to 200°C.
Housed in 3.2 x 1.5mm, hermetically sealed, non-magnetic ceramic packages, CXOLHT oscillators are available in frequencies from 16kHz up to 50MHz with typical supply current requirements from <20µA at 30.768kHz frequency output. Supply voltage requirements are 2.5 to 3.3V ±10% with CMOS output load of 15pF. Additional specifications include duty cycle of 45% minimum 55% maximum, ageing in first year of ±5ppm at 25°C and fast start up time of 4 to 8ms depending on frequency.
Two enable/disable options are available offering a tri-state output with oscillation disabled internally when output is put into high Z state.
The CXOLHT oscillators feature frequency stability over temperature range characteristics of ±150 to ±125ppm (25 to 150°C), ±175 to ±150ppm (25 to 175°C) and ±200 to ±175ppm (25 to 200°C) and are capable of withstanding process temperatures up to 260°C for up to 20 seconds. Packaging options are tray pack or tape and reel per EIA 481.
Ideal for use in high shock and vibration environments, applications include downhole instrumentation, underground boring tools, geothermal, measurement while drilling (MWD), industrial and avionics.
