5. USB Connection: Connect the Type-C line to the USB 3.0 Port for data transfer or debugging purposes.
6. RF Connections: Use the SMA wires to connect to the 16-way ADCs (14-bit, 2.5GSPS) and 16 DAC ports (14-bit, 9.85GSPS) as required by your application.
7. Optional M.2 SSD: If using an M.2 SSD, connect it to the M.2 interface. Note that users need to purchase the M.2 SSD separately.

4. Operating Instructions

The AXW49 board leverages the Zynq UltraScale+ RFSoC's heterogeneous computing architecture, which includes a complete ARM processing subsystem, FPGA architecture, and analog-to-digital programmability in the RF signal chain.

4.1. Core Architecture and Processing

The Zynq UltraScale XCZU49DR FPGA chip integrates Quad ARM Cortex-A53 and Dual ARM Cortex-R5F processors. This architecture supports parallel execution of real-time operating systems (RTOS) and Linux, enabling efficient processing of complex algorithms.

4.2. RF Direct Sampling and Synchronization

The board features 16-channel 14-bit RF direct mining technology, allowing for integration with heterogeneous multi-board synchronization. This technology enables direct RF sampling, reducing the complexity of the RF signal chain and improving performance.

4.3. High-Performance ADC/DAC Operation

The AXW49 supports 16 14-bit ADCs with a 2.5GSPS input and 16 14-bit DACs with a 9.85GSPS output. It handles single-ended signal input and output, performing differential single-ended interconversion through balun devices for data transmission and reception. The VCM signal also leads to TP, allowing users to adjust common mode voltage.

4.4. Application Scenarios

The board is designed for extensive application scenarios, including:

• Satellite Communication: Utilizes direct RF sampling and ZYNQ RFSoC for signal generation and analysis.
• 5G and LTE Wireless Technology: Enables wireless infrastructure manufacturers to achieve significant chopping block reduction in area and power consumption, crucial for MIMO technology development.
• Radar Signal Processing and Data Link: Supports 16-channel ADCs and 16-channel DACs for low latency transceiver applications.
• Test and Measurement: Provides a high-speed multifunctional instrument for signal generation and analysis through direct RF sampling, high flexibility, and software programmability.

5. Maintenance

To ensure the longevity and optimal performance of your Alinx AXW49 RF Development Board, follow these general maintenance guidelines:

• Keep Clean: Regularly clean the board with a soft, dry brush or compressed air to remove dust and debris. Avoid using liquids or harsh chemicals.
• Storage: Store the board in a dry, anti-static environment when not in use.
• Handle with Care: Always handle the board by its edges to avoid touching sensitive components. Use anti-static precautions (e.g., wrist strap) when handling.
• Environmental Conditions: Operate the board within the specified ambient temperature range of -40°C to 70°C. Avoid extreme temperatures or humidity.

6. Troubleshooting

If you encounter issues with your Alinx AXW49 RF Development Board, consider the following general troubleshooting steps. For complex problems, wiring diagrams, driver files, or specific technical documentation, please contact customer service.
