SoC Blockset Support Package for Xilinx Devices / SDR / RFSoC

Description

The OTAVA DTRX2 block integrates the OTAVA DTRX2 mmWave radio card with the Xilinx® Zynq® UltraScale+™ RFSoC ZCU208 Evaluation Kit. The block provides an RF front-end interface in the millimeter-wave (mmWave) frequency band to implement your RF applications on the ZCU208 board.

The block supports the mmWave frequency band in the 19 to 31 GHz range. Use this block to target applications in 5G, radar, and satellite communications in Ka or Ku band.

The block accepts a vector of N samples through the IFInx ports and outputs 16-bit samples packed into N x 16 bits through the RFOutx ports. N is the number of samples per clock cycle and x is 1 or 2. The block accepts 16-bit samples packed into N x 16 bits through the RFInx ports and outputs a vector of N samples through the IFOutx ports based on the value of N.

In generation, the SoC Builder tool maps the control path interface for the configuration of the DTRX2 radio card on the hardware.

The block supports a maximum of two transmit (TX) and two receive (RX) channels. These channels correspond to the TX and RX channels of the DTRX2 radio card.

RFIn2 - IFOut2RX2

To integrate the OTAVA DTRX2 block with the RF Data Converter block, follow these instructions.

  • Connect TX1 with DAC2 in Tile1.

  • Connect TX2 with DAC1 in Tile1.

  • Connect RX1 with ADC8 in Tile4.

  • Connect RX1 with ADC7 in Tile4.

Note

  • Do not target any signal to the DTRX2 radio card when the card power switch is off. Turn the power switch on before targeting the card.

  • For reference clock spurious mitigation, use a 10 dB coaxial attenuator or a low-pass filter with a cutoff value greater than 122.88 MHz between the CLK104 output and the REF_CLK_IN input of the DTRX2 radio card.

  • Terminate all unused RF channels input and output connectors of the DTRX2 radio card with 50 ohms 2.92 mm terminations.

For detailed instructions on setting up and using the mmWave radio card, see Wideband mmWave Radio Dev Kit for RFSoC Gen-3 on the Avnet® website.

Examples

Transmit and Receive Tone Using OTAVA DTRX2 mmWave Radio Card

Transmit and Receive Tone Using OTAVA DTRX2 mmWave Radio Card

Integrate an OTAVA DTRX2 mmWave radio card with a Xilinx® Zynq® UltraScale+(TM) RFSoC ZCU208 Evaluation Kit by using SoC Blockset™. In this example, you design, simulate, and deploy a system that generates a sinusoidal tone from an FPGA and transmit the tone in mmWave band through mmWave radio card by using the RF Data Converter (RFDC) and OTAVA DTRX2 blocks. The system then receives the data back into the FPGA by using the OTAVA DTRX2 and RFDC blocks and visualizes the received tone by using an embedded processor.
