<p style="line-height:1.8"><span style="color:#000000;font-size:14pt">串口下载的RX和TX与主控连接的信号线需要采用差分布线和包地，等长处理，提高抗干扰能力，避免时序偏移和共模噪声的引入。</span></p>

<p style="line-height:1.8"><span style="color:#000000;font-size:14pt">运放芯片LM4871N的3脚和4脚也要采用差分布线，振幅相同，方向相反，5脚和8脚连接喇叭的两根信号线也要等长处理，阻抗匹配。由于主控频率有240MHz，所以信号线的连接要格外注意。</span></p>
<p style="line-height:1.8"><span style="font-size:14pt">电容下方尽量不要走线，减少信号干扰。</span></p>
