Description
CTS Model 197 is a high stability double oven OCXO developed to meet stringent Long Term Evolution (LTE)
performance requirements, offering 1.0 ppb (p-p) temperature stability over the industrial temperature range. It
provides excellent 1 μsec typical holdover performance with ±10°C temperature variation. Other applications
ideally suited for this OCXO include high performance instrumentation, communications systems, and rubidium
replacement.
