Technology Leadership: 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.
Housed in a hermetically sealed ceramic package, the tiny crystal measures just 2.0 x 1.2 x 0.4mm and 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 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.
New High Frequency VCXO: Our recently launched IQXV-100 VCXO is available over an extended frequency range from 60 to 800MHz combined with a wide pulling range up to +/-250ppm. Housed in a surface mount 14.4 x 9.5 x 6.0mm metal can package with FR4 base and an LVPECL output, this low phase noise SMD VCXO is particularly suitable for Ethernet, Fibre and Optical Networking Applications.
New Ultra Miniature Crystal: IQD Frequency Products launches a new ultra miniature crystal, the IQXC-26. This ultra miniature 4-pad crystal is housed in a 1.6 x 1.2 x 0.4mm ceramic package which has a seamed sealed metal lid. This lid is grounded in order to reduce the effects of EMC radiation. This makes the IQXC-26 ideal for use in all wireless based applications
