IQD launches miniature telemetry crystal
IQD has launched a new crystal, the CX-16 series which is designed for use in medical implantable devices. The new device is specifically targeted at applications in the fast growing medical RF telemetry market.Hous
Initially offered in frequencies of 24MHz and 26.5MHz, other frequencies are being developed throughout 2011 including 32.768kHz. The CX-16 offers a calibration tolerance of +/-5ppm and will deliver temperature stabilities of +/-10ppm over the commercial operating temperature range of -10 to +70 degrees C and +/-30ppm over the extended military temperature range of -55 to +125 degrees C.
The ceramic package with glass lid design prevents out-gassing and contamination which is crucial to achieving its excellent ageing characteristic of better than +/-3ppm max over the first year. This low ageing performance is crucial when used in medical RF telemetry applications. The specific C0/C1 ratio, Q and ESR levels which the CX-16 crystal can meet ensures that it is suitable for medical applications where remote communication between devices such as pacemakers and defibrillators etc and consultants/medical support staff is required.
