Dynamic Engineers has released a new ultra low power timing module for underwater. The TM3934CJ-LP-16.384MHz-A offers the following features:
- Frequency: 16.384
- Supply Voltage: 3.3V
- Steady Current: 20mA Typ
- Output Waveform: HCMOS
- Hold over Stability: ±600µs over 24h
- Aging: ±5ppb per day
- Operating Temperature: -10°C to +45°C (-40°C to +85°C optional)
- Size: 39.0 x 34.0 x 5.2mm
The TM3934CJ-LP-16.384MHz-A is the least consuming precision clock module of DEI. It uses a 50mW 16.384 EWOS and the TM3934CJ-LP-16.384MHz-A 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 a 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.
TM3934CJ-LP-16.384MHz-A 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.
