MEMS-based programmable oscillators with sensational 600 fs of phase jitter and continuous frequency stability of ±10 ppm

As with all MEMS-based oscillators from SiTime, the new SiT8208 and SiT8209 programmable oscillators, which operate from 1 MHz to 80 MHz and 80 MHz to 220MHz respectively with supply voltages of 1.8 V and 2.5-3.3 V, also deliver six decimal places of accuracy. The programmable drive strength of the device allows a very simple impedance matching and a very effective EMI reduction. Furthermore, high-drive options that can be used to drive multiple loads without additional buffers result in a further reduction of the circuit complexity and thus a cost-reduction.



The SiT820X family comes with an array of programmable features, such as frequency, stability and supply voltage, and is suitable for use in telecom, networking, storage and wireless applications. According to customer request, devices of the SiT820X family, with over 200 derivatives, can be configured as drop in replacements for existing quartz and SAW oscillators and are available in industry standard 3225, 5032 and 7050 packages.



Customized samples of the MEMS-based programmable oscillators, available for both the commercial temperature range of -20°C to +70°C and the industrial temperature range of -40°C to +85°C, can be shipped in three to five working days and production quantities in three to five weeks after receipt of the order.
