BOARD MOUNTED GPSDO KIT (PCB-MOUNTED GPS-DISCIPLINED TCXO) 

This is a GPS-disciplined, temperature-controlled crystal oscillator (GPSDO), which is recommended for use with a USRP B200/B210.  The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal, which allows developers to build systems that serve applications with improved frequency accuracy (75 ppb in unlocked condition) or global timing alignment (50 ns in locked condition).

Overview

Overview

This is a GPS-disciplined, temperature-controlled crystal oscillator (GPSDO), which is recommended for use with a USRP B200/B210.  The GPSDO provides a high-accuracy 10 MHz reference and 1 PPS signal, which allows developers to build systems that serve applications with improved frequency accuracy (75 ppb in unlocked condition) or global timing alignment (50 ns in locked condition).

Unlike the OCXO-based version, which is recommended for use with the USRP X300/X310, this lower power module can be used with the USRP B200/B210 in a USB bus-powered configuration. 

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