We were configuring the AD9528 with input Ref clock REFA and VCXO .The configuration was successful. Now we want to change the input Ref clock to REFB instead of REFA, for this I have changed registers
0x0108 from value 0x2a to 0x52
0x010a from value 0x2 to 0x3
With the above changes after configuring the AD9528 when I am reading the readback register 0x0508 the value is found to be 0xea . This means the PLL1 is not getting locked.
While change the input reference clock from REFA to REFB is there any other register we need to change apart from the above mentioned registers ?
Thank You in advanced .
