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, which allow developers to build systems that serve applications with improved frequency accuracy and global timing alignment.
