IQCM-100 Datasheet | IQD

Description A GNSS disciplined OCXO incorporating sync to a 1PPS input and 1PPS output. patible with GPS, GLONASS, BEIDOU and GALILEO. Holdover stability up to 1.5µs over 24hours, achieved using an adaptive algorithm. Internal parameters of the algorithm, including maintenance alarms and message are available to the user via serial port. Frequency stability better than 1E-12 Application Information (Reference Drawing): Connect the 1PPS output of your GPS system to the IQCM-100. A MCU can be used to monitor the working state of the IQCM-100. Working States (Reference Drawing): Run1: Fast track. Adjust the OCXO 10MHz output frequency quickly to track the 1PPS to 10MHz with 1PPS reference. Run2: Slow track. Adjust the OCXO 10MHz output frequency slowly when phase error is in the defined range. Holdover: No 1PPS input present; an algorithm enables adaptive modelling of the frequency stability of an OCXO with reference to the GPS timing signal. Free Run: Clock...
