New Product Announcement: Ultra Low Power Timing Module for Underwater - TM3934CJ-LP-16.384MHz-A

  • May 03, 2021

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.
