IQCM-110 데이터시트, 핀배열, 회로
ISSUE 1; February 2016
Description
A GPS disciplined OCXO incorporating GPS receiver unit, to
give 1PPS and 10MHz output.
Holdover stability up to 1.5µs over 24hours, achieved using an
adaptive algorithm.
Standard NMEA0183 data is available to the user via serial
port.
Frequency stability better than 1E-12
Working States (Reference Drawing):
Run1: Fast track. Adjust the OCXO 10MHz output frequency
quickly to track the GPS.
Run2: Slow track. Adjust the OCXO 10MHz output frequency
slowly when phase error is in the defined range.
Holdover: No GPS 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 GPS input.
Note1: The IQCM-110 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-110 will
operate in Holdover mode regardless of the 1PPS signal
condition.
NMEA data words
The following standard GNSS data is available to the user via
the interface on pin 6 and pin 7. GPRMC, GPVTG, GPGGA,
GPGSA, GPGSV, GPGLL, GPZDA these are broadcast every
second in sync with the 1PPS output
