LPFRS Oscillator Overview

Request Info or Quote

The LPFRS is a low-cost, low-profile and high-performance rubidium oscillator source. It is compatible to the FEI 5650 Rb model and comes in a low-profile package and 2 outputs. It features low phase noise performance.

The LPFRS is RoHS compliant through the NIE exemption of the RoHS Directive 2011/65/EU, Article 4.6/Annex III-7(b), allowing exemptions of Pb free soldering for specific applications such as telecom, including servers, storage array systems, network infrastructure equipment for switching, signalling, transmission, and network management for telecommunications.
