One of the world’s leading silicon crystal oscillator developers has launched the smallest surface mount crystal in the world for medical equipment such as pacemakers.

IQD Frequency Products in Crewekerne, Somerset, supplies oscillators to customers in over 60 countries, and has developed a hermetically sealed package measuring just 1.55 x 0.95 x 0.35mmfor frequencies between 30MHz and 50MHz.

The CX-18 was launched at Electronica this week and is aimed at implantable medical applications including cochlear implants, defibrillators and cameras that are implanted into the retina and so has a low aging characteristic of under 1ppm over the first year.

… and a high frequency MEMS oscillator

Building reliable oscillators from a silicon process rather than from pure silicon materials is a key target for reducing the cost and leadtimes of oscillators, and IQD in Somerset has developed a high frequency MEMS oscillator.

The IQMS900 series is built in a standard CMOS process, giving lower costs and lead times of 1 to 6 weeks, and runs from 1MHz to 800MHz by tuning the micromachined MEMS structures. It is aimed at telecoms infrastructure designs such as Fibre Channel, 10G Ethernet, HDMI and USB3 with a typical jitter of 0.7ps at 200MHz. The frequencies are stable to +/- 10ppm from 0 to 70degC, or +/-15ppm at -40 to +85degC.
