Miniature telemetry crystal for use in medical implantable devices
The crystal is manufactured using a photolithographic and chemical milling processes and then sealed within a ceramic package for high stability and low aging. Initially offered in frequencies of 24MHz and 26.5MHz, other frequencies will be developed throughout 2011 including 32.768kHz.
The CX-16 features a calibration tolerance of +/-5ppm and will deliver temperature stabilities of +/-10ppm over the commercial operating temperature range of -10 to +70ºC and +/-30ppm over the extended military temperature range of -55 to +125ºC.
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. 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 and consultants/medical support staff is required.
