IQD Frequency Products debuts its first oscillator families based on MEMS (microelectromechanical systems) technology at Electronica 2009. Designed to replace standard XOs (crystal oscillators) and VCXOs (voltage controlled crystal oscillators) in mass-market applications, the new IQMS-100, IQMS-200, IQMV-300 and IQMV-400 ranges offer cost savings of up to 50%, depending on volume, at comparable levels of performance to conventional quartz-based devices.
While conventional XOs require their quartz resonators to be hermetically sealed in a metal-capped package, MEMS resonators can be encapsulated directly within a silicon substrate. MEMS oscillators therefore have a number of advantages over their quartz crystal counterparts, including:
• smaller package size
• reliability, due to inherent shock and vibration resistance
• low prices at high volumes, due to the low manufacturing cost of CMOS wafers.

IQD Frequency Products has launched a new range of low-cost miniature quartz crystals for use as timing sources in consumer electronics and computing applications. The new CFPX-181 series is available in a range of fundamental frequencies from 16.0MHz to 50MHz. Housed in a hermetically sealed, four-pad ceramic SMD package measuring just 2.5 x 2.1mm, the CFPX-181 series is suitable for use in set-top boxes and personal video recorders (PVRs), games consoles, smart card readers and a wide variety of computer peripherals and IT equipment with tight space and cost limitations. For accurate performance at high data transfer rates, the CFPX-181 can be specified to stabilities as good as 10ppm over an operating temperature range from -10° to +60°C. Crystal ageing properties are also excellent at just 1ppm per year (maximum, at +25°C).
