项目编号:P207
文件大小:137M
图纸说明:PCB图
开发环境:AD2020
简要概述:
冥王星sdr固件移植工作已全部完成,在不侵入系统的情况下刷新固件,默认为AD9364。
在BOM成本方面,ZYNQ7010/ZYN17020和AD9363的成本约为150-200元人民币,芯片拆卸后。使用全新芯片没有讨价还价的能力,因为BOM数量少,成本在1000元左右。
1.硬件解决方案
FPGA:ZYNQ7010/7020(ZYNQ7010和ZYNQ7020可以相互替换,如果您需要更多的硬件资源,请使用ZYNQ7020)
RF:AD9361/AD9363/AD9364(三个芯片可以相互替换,区别在于带宽。其中,AD9361性能更好,尽量使用ABCZ尾端芯片,与BBCZ不同)
AD9363ABCZ Band: 325 MHz to 3.8 GHz
AD9363BBCZ Band: 650 MHz to 2.7 GHz
RAM Memory: DDR3 256M16
USB-PHY: USB3320C
GMAC-PHY: RTL8211E-VL (RTL8211E has two endings, VB and VL, where VB level is 3.3V/2.5V, VL is 1.8V)
QSPI FLASH: W25Q256 32MB
Power supply topology diagram
block design
Support Pluto-SDR firmware transplantation, OpenWiFi (ZYNQ7020 FPGA required), support adi official ZED+AD-FMCOMMS2/3/4 related firmware code
Design software: Altium Designer Kicad
Number of layers: 4 layers (signal layer[1]、GND[2]、POWER[3]、signal layer[4])
Craft: JLC PCB Craft
Impedance: not supported
The impedance version will be tested in March 2021, and the openwifi port is currently undergoing normal transceiver tests.
Support for Zynq-7020 and Zynq-7010 in 400pin BGA package
Support 2R2T transceiver mode
4 layer board to reduce cost
SD slot for running real Linux distros
Support Gigabit Ethernet
