In the last decade, micro-electromechanical systems (MEMS)
oscillators began replacing quartz
oscillators in many applications, including high-reliability automotive applications [4].
0 mm (7050) standard plastic packages, and are pin-to-pin compatible with traditional crystal
oscillators, making them an ideal upgrade solution.
According to industry executives, iPhone 5's crystal
oscillators command higher profit than iPhone 4's, inspiring estimates that the brisk additional orders would considerably increase the company's gross margin for the third quarter by 10% sequentially.
Also Q can be approximated by R[square root of C/L] for the LC
oscillators where the variables are the resonator components.
Made by European frequency product specialists Euroquartz, HCK series
oscillators are available now from Saelig Co.
Against this background, how do MEMS-based resonators and
oscillators compare?
Here you have parts pricing reduced compared to programmable quartz
oscillators, and the lead time is reduced if not better.
COMING ATTRACTIONS Scientists are considering where, beyond MRAM and
oscillators, this new form of electromagnetic muscle is leading.
DCSOs, which are depicted much like a high Q planar resonator in an equivalent circuit, can achieve the phase-noise performance of CRO/SAW
oscillators but over a wide tuning and operating temperature range at low cost.
The frequencies of the two
oscillators, the reference signal and the offset, must add up to the fixed reference frequency of the cavity.
Fluidized bed
oscillators are
oscillators containing screen or perforated decks and a lower air chamber.
The market size of crystal
oscillators in 2013 is expected to be $2,033.
