Euroquartz adds three Statek miniature quartz crystal ranges
Frequency control specialist, Euroquartz has announced the availability of three ranges of miniature quartz crystals from Statek. The CX16, CX18 and CX20 series are designed for use in medical-implantable wireless RF transceiver applications using Bluetooth Low Energy (BLE) or Medical Implant Communications Service (MICS) specifications.
The CX16, CX18 and CX20 series miniature devices operate in the 16MHz and above frequency range requested by BLE transceiver integrated circuits (ICs). In medical applications, where miniaturisation is paramount Statek’s, low profile CX16 AT quartz crystal is particularly suitable, measuring 2.0 x 1.2mm and 0.43mm high. Frequencies range from 24 to 50MHz. According to Euroquartz, the CX16’s resonator is manufactured using state-of-the-art photolithographic and chemical milling processes and sealed in a ceramic package for high stability and low ageing. CX16 crystals are available with tight calibration tolerances and high stability over temperature plus fast start-up times.
Medical applications include medical telemetry, pacemakers, defibrillators, neuro-stimulators, infusion pumps and cochlear implants. Additional characteristics include high shock and vibration survival with full military testing also available for defence and aerospace applications.
Smaller still is the CX18 series, measuring 1.6 x 1.0 x 0.38mm and offering frequencies from 30 to 50MHz. It is also lightweight – just 1.8mg. The CX18 series is suited to similar medical applications as the CX16, as well as military and aerospace applications such as missile telemetry, ruggedised communications, aircraft electronics and smart munitions with full military screening available. CX18 series crystals are also suitable for a range of industrial and communications applications such as bio-tracking, process control and portable instrumentation.
Statek CX20 telemetry crystals have a footprint of 2.5mm x 1.2mm and height of 0.5mm with frequency ranging from 16 to 50MHz. Suitable applications are low power wireless communications, implantable transceivers for the medical sector, as well as smart munitions, guidance and navigation and communications in military and defence. The CX20 crystals can also be used in industrial communications, transmitters, pulse generators, tracking beacons and wildlife telemetry.
All three ranges are available with commercial (-10 to +70 degree C), industrial (-40 to +80 degree C) and military (-55 to +125 degree C) operating temperature ranges with packaging options of tray pack and 12mm tape and reel (8mm for CX16).
