DS125DF111: 器件必须连接到Sigcon GUI才能锁定CDR

renjie song

Part Number: DS125DF111

当使用器件时，配置12.5G的二分频去重定时6.25Gbps的数据时，将管脚ADDR0/LOCK作为CDR状态检测的管脚，按照手册说明，当CDR锁定时该管脚将输出高电平。但是在使用时，发现该管脚始终为低电平，只有当把器件连接到Sigcon GUI并且打开state monitor连续更新状态后，CDR才显示锁定并将该管脚输出为高电平。并且当输入信号断掉再重新给retimer 之后，CDR无法锁定，同样是必须打开monitor持续update后才能锁定。想请问这个问题如何解决？

你好，

您能否共享可比较的锁定和非锁定DS125DF111通道的寄存器转储？此外，您从DS125DF111寄存器0x02中读取了哪些值？

你有烧写指南吗？如果是这样，您是否尝试过按照表7、8或9配置设备，并查看设备是否锁定在CDR上？
