This device provides a highly stable reference clock across a wide range of temperatures and is ideal for providing an accurate clock in the absence of a GPS reference. The holdover performance should be better than 370 parts per billion (370ppb) in 24 hours for Stratum 3 level performance and 12ppb in 24 hours for Stratum 3E performance.
