您好，Noel
您能否提供所有寄存器值和顺序的列表、我在尝试后仍返回到几个
此致
尊敬的 Panhua：
请按照相应过程操作、并使用 TICS Pro 来生成寄存器值。 或者、请详细描述您编程的内容和顺序、我们将回顾这些内容。

请检查它。
这是步骤1中的寄存器集、另一个 步骤的寄存器集是什么？
我只配置了以下寄存器来完成初始化、在上电后、锁定有可能会发生故障。 您是打算遵循以下寄存器设置吗？ 我已经尝试过了、结果出了问题。

根据寄存器设置、您仅使用 OUTB。 您已将 PINMUTE_POL 设置为低电平有效。 除非将 MUTE 引脚拉至高电平、否则 OUTB 将被静音。
在初始化期间，R0[13]应该为1。(第123,125行)
第二个 R0编程(第125行)、R0[4]应为1。
请在修复上述寄存器设置后、让我知道您是否能够一致地将 LMX2820锁定到5650MHz。
您的即时校准序列不正确、如果步骤成功、请按照编程序列(步骤2至10)进行操作。

这些寄存器配置是否是这样的？
您的初始寄存器设置正确、是否锁定了？
lmx2820可以被锁定。
每次我的操作在断电后初始化、所以重复很多次、或者失锁现象将和之前一样出现、几乎十次。
目前我还没有找到原因。 如果 LMX2820未打开 、即时校准，重复操作不会导致失锁
让我们首先关注行1到行125。 您获得了100%的成功率吗？
这一切都是成功的,我已经尝试了至少50次,我已经尝试了不同的硬件和现象是一样的。
好的、步骤1已完成。 现在继续执行步骤2至步骤10 (第127至135行)。
REG70 = 24'h46_00FE、 REG0 = 24'h00_4620，--> 4630 REg1 = 24'h01_57A2 reg2 = 24'h02_8266，-->可以跳过，初始化已对此值进行编程 REg1 = 24'h01_57A3、 REG44 = 24'h2C_FD6A、-->可以跳过，初始化已编程该值 REG0 = 24'h00_4630、 //wiat 100ms REG0 = 24'h00_4620、
由于此配置的 INSTCAL_DBLR_EN = 1、因此在步骤10之后可能没有输出。 在这种情况下、复位器件并再次执行第1步到第10步。
