Euroquartz has launched a new range of miniature crystal oscillators from Statek Inc offering ultra-low current and developed for high-reliability applications. Hermetically sealed in a highly reliable ceramic housing, the new CXOU oscillator is available in frequencies from 32.768kHz to 100,000kHz.
The CXOU offers ultra-low current consumption from 1.75µA to 3.9µA, depending on frequency output, with start-up voltages from 0.9V to 5.0V. Standard calibration tolerances are ±20ppm, ±50ppm and ±100ppm with tighter bands available to special order if required. Typical start-up time is 200ms with rise / fall times of 30ns, while ageing is ±2ppm for the first year. Standard CMOS output load is 10pF with other loads available to special order. The new crystal oscillators are also capable of withstanding peak shock up to 5,000g (0.3ms ½ sine).
Housed in a non-magnetic, helium-impermeable ceramic package and lid measuring just 1.2mm x 2.0mm x 0.76mm, the CXOU range of oscillators is ideal for use in many medical implantable applications including pacemakers, defibrillators and neuro devices, as well as external medical products. With full military testing per MIL-PRF-55310 available to order, the oscillators are also suitable for many defence and aerospace applications.
Additional features and specifications include tristate enable / disable options and operating temperature ranges for commercial (0°C to 70°C), industrial (-40°C to 85°C) and military (-55°C to 125°C) applications. Process temperature rating is 260°C for two minutes maximum.
Statek CXOU oscillators are available in tray packs or 12mm carrier tape 178mm or 330mm reels (EIA481).
