The Austron 1295C is a GPS Disciplined Oscillator (GPSDO) that delivers a highly accurate and stable frequency reference for precision timing and synchronization applications. By leveraging GPS satellite signals to discipline an internal oscillator—typically an Oven-Controlled Crystal Oscillator (OCXO)—the 1295C achieves exceptional long-term frequency stability and parts-per-billion accuracy within minutes of power-on. The unit integrates a GPS receiver, maintains timing accuracy during GPS signal loss through internal oscillator holdover, and outputs a primary 10 MHz frequency reference along with a Pulse Per Second (PPS) signal aligned to UTC. Standard interfaces include GPS antenna input and RS-232 configuration control, with power consumption in the hundreds of milliamps range once stabilized.
