evaluation board introduction
TL6678ZH-EVM evaluation board based on TI KeyStone architecture C6000 series TMS320C6678 octa-core C66x fixed-point/floating point DSP, and Xilinx Zynq-7000 series XC7Z045/XC7Z100 SoC processor design.
TMS320C6678 can have a main frequency of up to 1.25GHz per core. XC7Z045/XC7Z100 integrates PS-end dual-core ARM Cortex-A9 + PL-end Kintex-7 architecture 28nm programmable logic resources. The internal DSP and ZYNQ of the core board are connected through the SRIO communication bus.
evaluation board interfaces are rich in resources, and they lead to dual-channel CameraLink, dual-channel SFP+ optical ports, four-channel gigabit network ports, dual-channel SATA, dual-channel PCIe, four-channel USB, dual-channel CAN, dual-channel CAMERA, HDMI IN/OUT, LVDS, LCD, RS485, RS232, Micro SD, HPC FMC and other interfaces, which facilitate users to quickly evaluate product solutions and technical pre-research.

. Case Description
This case is based on the ADI AD9361 module AD-FMCOMMS3-EBZ and Chuanglong Technology TL6678ZH-EVM evaluation board to build an AD9361 RF (Radio Frequency) transceiver and receive test platform, realizing QPSK (Quadrature Phase Shift Keying) digital modulation and FM (Frequency Modulation) listening. AD-FMCOMMS3-EBZ module development official reference link: https://wiki.analog.com/resources/eval/user-guides/ad-fmcomms3-ebz.
2. Case test
2.1 QSPK digital modulation test
Please connect the TX1A and RX1A of the AD-FMCOMMS3-EBZ module to 2.4G antennas respectively, and connect the module to the FMC interface of the evaluation board. The J1 jumper cap of the evaluation board selects the 2.5V gear to configure the BANK voltage of the FMC IO to 2.5V. At the same time, use the network cable to connect the evaluation board PS RGMII0 ETH network port and the Ubuntu upper computer to the same router.

.2 FM Listening Test
Please connect the RX1A of the AD-FMCOMMS3-EBZ module to the FM antenna and connect the module to the FMC interface of the evaluation board. The evaluation board J1 jumper cap selects the 2.5V gear to configure the BANK voltage of the FMC IO to be 2.5V. At the same time, use the network cable to connect the evaluation board and the Ubuntu upper computer to the same router. Connect the USB sound card to the evaluation board USB HOST interface and connect the headset to the audio output of the USB sound card.
