The CX-16 series crystal launched by IQD is designed for use in
medical implantable devices. The device is specifically targeted at
applications in the fast growing medical RF telemetry market and comes
housed in a hermetically sealed ceramic package measuring just
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
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 aging
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.
