The latest addition to IQD's comprehensive frequency product range, the CX-18, is believed to be the smallest and lightest surface-mount crystal in the world. Housed in a hermetically sealed ceramic package, the tiny crystal measures just 1.55 x 0.95 x 0.35mm with a typical weight of 1.8mg. Frequencies can be specified between 30MHz and 50MHz with frequency temperature stabilities of +/-10ppm over the commercial operating temperature range of 0 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 +/-1ppm over the first year. This low ageing performance is crucial when used in invasive medical applications. The CX-18 is particularly suitable for use in telemetry for implantable pacemakers (CRTs). The wireless remote control of an RF pacemaker allows doctors to communicate the results of specific parameters, capture the threshold results from the atrium or the ventricle for instance and to alert clinics by sending information directly to the monitoring equipment. This crystal can also be used in hearing aids, cochlear implants, defibrillators and for retina implantable systems that use camera technology. IQD's products are specified by leading manufacturers in the aerospace, automotive, communications, computing, consumer, industrial, medical and military industries throughout the world. We work with several premier chip-set designers on a variety of key projects and hold approvals on a number of products including high specification oscillators.
