MEMS oscillators are a valid alternative to older, more established quartz crystal oscillators
, offering better resilience against vibration and mechanical shock and reliability with respect to temperature variation."

As the demand for very small crystal oscillators
has grown, it hasn't been possible simply to scale down existing designs.
This provided the capability to rule out other possible factors that could have affected the crystal oscillator
Performing over an output frequency of 26 MHz, Valpey Fisher's VFTX312 temperature compensated crystal oscillator
(TCXO) includes a voltage control option from 0 V to 3.3 V that is suitable for femtocell (3GPP) reference timing.
The model 357 surface-mount voltage controlled crystal oscillator
(VCXO) features a frequency signal output that will interface with HCMOS electronic circuitry.
Vectron International announced its Model VTM3 small temperature compensated crystal oscillator
(TCXO) that offers phase noise performance in a small package (3.2 mm X 2.5 mm), enabling customers in the communications, industrial test and military markets to use a small, low power oscillator without compromising stability and phase noise performance.
The model F4500 series crystal oscillator
offers an input voltage of 1.8 V [+ or -]5 percent, with an operating voltage as low as 1.6 V.
Vectron International announces the expansion of its C3430 frequency controlled crystal oscillator
(FCXO) family for use in wireline infrastructure, test and measurement, military applications and wireless infrastructure such as GSM, CDMA and W-CDMA base stations and point-to-point radio.
The EX-380/385 series evacuated miniature crystal oscillator
(EMXO[TM] bridges the gap between current large, high precision OCXOs and smaller TCXOs and is an ideal choice when there is a need for spectral purity, short and long term stability, along with small size and reduced power consumption.
The transceiver also features two crystal oscillator
circuits which can be used to measure the frequency of the incoming clock, or they can generate a clean master clock when there is no lock on the input or no external clock.
The model XOV222 low noise voltage-controlled crystal oscillator
is designed with portable applications in mind and operates on +12 to +15 V DC with a typical current draw of 50 mA, The oscillator offers an excellent solution for very low noise requirements where space is a problem.
