SGTM16HP-UW Crystal GPSDO
High Performance Timing Module for underwater systems
SGTM16HP-UW is the best trade-off between low aging drift and low power consumption within Syrlinks’ SGTM portfolio. It uses the EWOS16HP OCXO at 16.384 MHz. The Timing module can be used as a PPS time keeper in all highly battery constraint underwater systems needing a precision OCXO-based clock. The module will automatically adjust the OCXO frequency and phase to an external 1PPS reference signal given by a GNSS receiver. Once locked and disciplined, it can be deployed in GNSS-denied environment (underwater) and the module will keep a precise synchronization in hold-over mode for the embedded electronics (typical aging ±0.2 ppb/day). SGTM16HP is ideal to reduce battery size and extend underwater mission time. Its thermal sensitivity is typically ±15 ppb but can be improved down to typically ±1ppb thanks to a specific firmware calibration on demand (-CT model).
