PMM5544 OEM Acoustic Modem

The PMM5544 is a high-performance underwater acoustic modem enabling robust communication, voice capability, and scientific data collection.

PMM5544 Features:

• Long-Range Acoustic Communication: 1–8 km depending on transducer, conditions, and modulation selected.
• Flexible Data Rates: 80 bps to 10,240 bps depending on the selected modulation scheme.
• Precise Acoustic Ranging: High-accuracy ranging capability (<0.3 m).
• Low Power Wake-Up: Energy-efficient standby operation with rapid activation.
• Customizable Linux Platform: Supports APIs for Python, MATLAB®, C++, JSON, JACK, and Socket integration.
• Simultaneous 4-Channel Hydrophone Input / 4-Channel Output: Unique to the PMM5544, this allows multi-channel sample-synchronous acoustic processing for integrating advanced sensing, beamforming, and detection applications.
• Integrated Single Sideband Voice: Includes SSB voice communications with adaptive squelch, VOX, and noise cancellation.
• High-Speed Dual-Core ARM Processor: Dual-core 1.4 GHz Arm® Cortex®-A53 processor for rapid data processing and efficient onboard control.
• Multiple Connectivity Options: Gigabit Ethernet, RS-422, and RS-232 interfaces for easy integration.
• Onboard Storage: 64 GB internal storage, expandable via microSD.

Optional Specialized Features (License Required):

• JANUS Support: Enables interoperable underwater communications using the NATO ANEP-87 standard.
• Phorcys Stheno + Euryale: Adds secure Phorcys communications with Stheno (20–28 kHz) and Euryale (8–12 kHz) capability. Euryale requires a compatible low-frequency transducer.
• MARIA: Unlocks the Marine Acoustic Rapid Innovation Architecture for custom acoustic algorithms, PCM data access, and advanced hardware control.
