RFX GROUP PT626-GPS16 disciplined OCXO. Incorporates a 16-bit DAC designed for smoother holdover transition and a new GPS receiver for improved sensitivity. The next gen design provides benefits for engineers wanting to replace rubidium and caesium frequency standards. Device can accept a variety of antennas to collect timing and positioning data from satellites which have on-board Caesium clocks and is therefore as accurate as class one timing standards when being disciplined. This is partly due to the accurate internal crystal controlled oscillators providing improved holdover stability with low phase noise. Product has a small footprint and is easily incorporated as a component within a system design.
