Ultra Low Power Timing Module

It uses a 50mW 16.384 EWOS and it can be used as a PPS time keeper in all highly battery-constraint underwater systems. The Module will automatically adjust the OCXO frequency and phase to the external PPS reference (under GNSS) with an record high precision at 10-11 level (0,02ppb). Once locked, it can be deployed in GNSS-denied environment (underwater) and will keep a precise synchronization in free-running mode for the embedded electronics. SGTM16 is ideal to reduce battery size and extend underwater mission time. Its thermal sensitivity is about ±30ppb but can be improved down to ±2ppb thanks to a specific firmware on demand.
