Which Frequency Reference Technology is Right for your Application?
Satcom references typically require a very low phase noise, stable 10 MHz reference. The noise requirement stems from the fact that the link frequencies are so high that that the 10 MHz has to be very low due to frequency multiplication.
Software Defined Radio
Many SDR systems involve multiple radios that must be stabilized and triggered precisely. Embedded oscillators in the radios must be disciplined and the trigger points be exact.
Portable references and timing solutions provide much needed accuracy in environments where a reference is not present or a GNSS locked reference is denied.
Tower Remote Sites
Major issue for references in multi-site digital systems is site to site synchronization. This invariably leads to a GPS locked reference.
Large Reference Systems
Large reference systems can involve hundreds of drops over multiple buildings while demanding accuracy and low noise.
General Lab Use
Most electronics labs require a stable 10 MHz frequency reference for frequency counters, spectrum analyzers and related equipment.
