GPSDO for USRP X Series (PCB-Mounted GPS-Disciplined OCXO)

This is a GPS-disciplined, oven-controlled crystal oscillator (GPSDO), which is compatible with a USRP X300 or X310.  The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal.  This allows developers to build system that serve applications with tight synchronization requirements, or global timing alignment within 50 ns.

Overview

Overview

This is a GPS-disciplined, oven-controlled crystal oscillator (GPSDO), which is compatible with a USRP X300 or X310.  It can also be used with the USRP B200/B210, but the system will require external power.  The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal, which allow developers to build systems that serve applications with improved frequency accuracy and global timing alignment.

We recommend reading the GPSDO Selection Guide to ensure this is the right device for your application.
