AD9528 write register invalid

Category: Hardware
Product Number: AD9528
Software Version: Qt 5.12.11

1、In my ad9258 chip, the 8th pin VCXO_VT pin is always low voltage. The second pin (rfa) and the third pin (rfa_n) have differential signal input.

2、No matter how the register value is modified, out13 always outputs the reference clock input by rfa, but if I write a reset command to 0x000, all registers return to their default values. In addition, how to modify other register values, it seems that the function has not changed. After several times of reading and writing the register, confirm that the register is readable and writable, and after writing the register, write the update command to the box 00f register.
