I'm using AD9517-4 for clock distribution. After configuration of it, I can detect the output with scope at OUT4~OUT7, no matter they are LVDS or CMOS.
But I can't find the output at OUT0~OUT3.
What is probably the cause?
Can you verify that Registers 0xF0 through 0xF5 (bits [1:0]) are set to 0x00? This will ensure that the LVPECL drivers are in normal operation mode.
You can also use the evaluation software to create a register setup file for your configuration.
Here is a user guide that explains the software and evaluation board.
If you are able to send me your setup file I can read through it and ensure everything is set correctly.
