design for precision timing applications," in IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, vol.
Although a MEMS-based oscillator appears to be straightforward, the development work required to achieve performance comparable to quartz crystal oscillators
has been significant.
The students mixed the output signal of the crystal oscillator
under test with a 10-MHz nonaccelerated reference signal via a frequency mixer.
Vectron International's C4500A1-0115 5-GHz SC-Cut oven-controlled crystal oscillator
(OCXO) demonstrates aging of < 50 ppb over six years.
The RFV300 voltage-controlled crystal oscillator
(VCXO) series features low jitter and phase noise, allowing full use of the allotted bandwidth in a system, as well as lower bit rate errors in optical data communications.
By completely eliminating the quartz resonator that must be cut and tuned for each crystal oscillator
(XO) frequency, the Si500 helps enable extremely short lead times.
The model FTS501AH oven compensated crystal oscillator
(OCXO) meets stratum level accuracy requirements for telecommunications applications, making it ideal for use in base stations, telecom switching, GPS and LAN/WAN applications as well as in test and satellite equipment.
Silicon Laboratories' 100 percent CMOS oscillator for consumer applications completely eliminates the quartz resonator that must be cut and tuned for each crystal oscillator
The VC-TCXO HFX series temperature-compensated crystal oscillator
(TCXO) is designed to increase performance for GSM and CDMA products.
