For the AD9162 SPI register configuration, do I only need configure the sequence register, without configuring other register. is there command for reading the sequence register.
Could you clarify your question a bit more for me, please? What do you mean by "sequence register" and "other register"? More details could help me better understand and address your question.
sequence register is START-UP SEQUENCE
A number of steps is required to program the AD9161/AD9162 to the proper operating state after the device is powered up. This sequence is divided into several steps, and is listed in Table 43, Table 44, and Table 45, along with an explanation of the purpose of each step. Private registers are reserved but must be written for proper operation. Blank cells in Table 43 to Table 45 mean that the value depends on the result as described in the description column.
The following pictrue Table 43 has the similar registers.
Some registers are not in these sequence,such as Register 0x304, Register 0x306,but I want to configure these two registers.How do I configure these similar registers???
Thank you so much for detailing your question.
Now I better understand your question. As you mentioned in your recent response, our startup sequence consists of programming number of registers and there is no such a thing called "sequence register". To get back to your question, you need to first setup the DAC as mentioned in the startup sequence tables 43 to 45. After setting up the DAC, you can start changing other register values using host digital processor (e.g. FPGA). Programming such registers as 0x304 or 0x306 need to be done in the body of your state machine not in the start-up sequence.
I hope this has addressed your question!
