MEMS oscillator offers 1 to 800MHz frequency range
EDN Europe, 03 Dec 2010
The new IQMS-900 series MEMS (micro electro mechanical systems) oscillator from IQD is available in a frequency range from 1 up to 800MHz. The new model can be factory programmed with either a LVDS (low voltage differential source) or LVPECL (low voltage positive emitter coupled logic) output. The plastic packaged oscillator series is available in two sizes: either 7x5mm or 5x3.2mm. Due to its MEMS technology design, phase jitter is low being typically 0.7ps at 200MHz. Two supply voltages are available, 3.3 and 2.5V. Frequency stabilities can be specified at either ±10ppm over an operating temperature range of 0 to +70°C or ±15ppm over -40 to +85°C. The oscillator is suitable for the incorporation into infrastructure equipment where it will provide accurate timing processes coupled with the ability to drive the high-speed processors that will enable the transfer of high data rates - the fast rise and fall times contribute to this. Typical applications include Fibre Channel, Ethernet 10G, HDMI, SATA/SAS & USB3. The devices are RoHs compliant and are available on tape and reel for production purposes.
