A World Leader in Low Noise Timing Solutions
Valpey Fisher Corporation - High Frequency, Low Phase Noise Timing Solutions
The VFH230C Series Hi-Rel clock oscillators are designed and manufactured to withstand extreme temperatures, shock, and vibration over the long haul. We offer a full line of Hi-Rel/COTS oscillators that give you military performance without the military price.

75 Years of Engineering Excellence.
 
Since 1931, Valpey Fisher has been a pioneer in the design and manufacturing of precision crystal oscillators.  Today, we are pushing even further to develop precision timing devices with the highest frequency and lowest phase noise.  We are the first to offer a series of TCXOs, VCXOs, and XOs that operate at 1.0GHz.  In addition, we offer complete timing modules, commercial oscillators, Hi-Rel/COTS oscillators, and VCOs to provide the precision timing required in optical networking, wireless infrastructure, test and measurement, and avionics. 
 
Valpey Fisher Ultrasound designs and manufactures a full line of ultrasonic transducers for use in aeronautics, petrochemical, medical, and semiconductor applications.
