Example
The DE70321 DemoKit is a complete AIS Class B (IEC 62287) technology demonstrator aimed at speeding manufacturers' design and development of AIS Class B transponders and AIS receiver products using the CMX7032 AIS Class B Baseband Processor with RF Synthesisers IC. This compact PCB-based product measures 100mm x 112.5mm. This design is a flexible platform to allow users to configure and evaluate with two build options:- Class B Transceiver (using CMX7032 FI-1.x)
- Dual Channel Rx-only (using CMX7032 FI-2.x)
- Shipped Pre-loaded with FI-2.x - Dual Rx-only Demonstrator
