IQCM-100 Image

The IQCM-100 is an OCXO with a holdover specification of 1.5 microseconds over a period of 24 hours when locked to a 1PPS (Pulse Per Second) input from an external GPS receiver, easily meeting industry standard holdover requirements. Incorporating an adaptive algorithm which has the ability to ‘learn’ from a stable GPS signal over a period of 2 days, the algorithm can be adjusted to allow for errors. Frequency is accurate to within ±1E-12 when locked to a 1PPS GPS signal and can compete with the performance of many atomic clock references.
