DP83TG720S-Q1: RGMII TX链路存在错误帧 RX链路无误

Part Number: DP83TG720S-Q1

Hi,

我们在用DP83TG720S的过程中,发现RGMII RX链路是正常的,RGMII TX链路始终存在错误帧。并且这种错误帧会存在抖动抖动情况(错误会产生变化,同时会伴随着正确帧)

目前硬件连接是交换机连接PHY芯片,采用RGMII 1Gbps,SWITCH未设置TX internal delay,PHY 的A2D_REG_48 Register寄存器是默认值960h,PHY处于RGMII TX shift模式

想确认一下这个问题是SWITCH发送端的不稳定还是PHY接收端的采样不稳定,同时这个问题的起因是什么,谢谢!
