項(xiàng)目編號(hào)：P207

文件大?。?37M

圖紙說明：PCB圖

開發(fā)環(huán)境：AD2020

簡(jiǎn)要概述：

冥王星sdr固件移植工作已全部完成，在不侵入系統(tǒng)的情況下刷新固件，默認(rèn)為AD9364。

在BOM成本方面，ZYNQ7010/ZYN17020和AD9363的成本約為150-200元人民幣，芯片拆卸后。使用全新芯片沒有討價(jià)還價(jià)的能力，因?yàn)锽OM數(shù)量少，成本在1000元左右。

1.硬件解決方案

FPGA:ZYNQ7010/7020（ZYNQ7010和ZYNQ7020可以相互替換，如果您需要更多的硬件資源，請(qǐng)使用ZYNQ7020）

RF:AD9361/AD9363/AD9364（三個(gè)芯片可以相互替換，區(qū)別在于帶寬。其中，AD9361性能更好，盡量使用ABCZ尾端芯片，與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

2. Software resources

Support Pluto-SDR firmware transplantation, OpenWiFi (ZYNQ7020 FPGA required), support adi official ZED+AD-FMCOMMS2/3/4 related firmware code

3. PCB board design

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.

4. Differences compared to ADALM-PLUTO:

• 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

5. Project display:
