The eight-channel embedded software radio platform is an embedded, miniaturized, multi-channel software radio platform developed for various wireless communication product development and communication teaching. The platform is composed of two parts, one is a wireless radio frequency signal transceiver module developed based on ADI 's ADRV9009 chip, and the other is a back-end digital processing module based on Xilinx's Zynq7100 chip. This platform is a high-performance, highly integrated wireless radio frequency signal transceiver processing equipment, suitable for the development of wireless communication teaching aids, miniaturized spectrum

Detection, broadband signal generator, wireless point finding and positioning development, etc. The basic performance indicators of the platform are as follows: 

• Baseband processor: ZYNQ7100 integrated dual ARM Cortex™-A9 processors 
• Interface: network port, optical port, serial port, USB , TF card, PL port I/O port, JTAG

1.1 XC7Z100-2FFG900I

The board uses the Zynq7000 series chip of Xilinx Company, the model is

XC7Z100-2FFG900I. The chip's PS system integrates two ARM Cortex™-A9 processors, AMBA® interconnect, internal memory, external memory interface and peripherals. These peripherals mainly include USB bus interface, Ethernet interface, SD/SDIO interface, I2C bus interface, CAN bus interface, UART interface, GPIO and so on. PS can run independently and start on power-up or reset.

1.3 Board Picture

2.1 main power interface 

The main power supply adopts +12V power supply, the maximum allowable input voltage is 14V , and the theoretical peak power consumption of the board can reach 80W . It is recommended to use a 12V10A power supply for power supply. The main power interface type is 6 -pin XH2.54 interface. 

2.2 Fan interface 

The board outputs is 5.5V power supply, which can supply power for the fan. When the board is used, please install a fan for good dissipation hot, otherwise there is a risk of burnout. 

2.3 clock 

2.3.1 PL clock

Onboard The 200MHz clock chip provides the clock for the PL terminal , the clock signal is a differential clock, and the level is standard LVDS .
