ISSUE 1; February 2016
Description
A GNSS disciplined OCXO incorporating sync to a 1PPS input
and 1PPS output. Compatible 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 module powered up with no 1PPS input.
Note1: The IQCM-100 should be left powered and running for 7
days minimum before operation to allow for the OCXO's
internal drift to stabilise.
Note2: The adaptive module algorithm can be built after two
days operation with good GPS signal, however this data will be
lost at power down.
Note3: When State input (Pin 8) is set low the IQCM-100 will
operate in Holdover mode regardless of the 1PPS signal
condition.
