we design a system with ad9518-1, but AD9518-1 pin outputs DC 1.6V, and the complement pin output DC 2.4V, no clock output, why?
If the output is static, check the following:
1. Is the SYNCb pin low?
2. Are you using the PLL? If so, is it locked?
Here's a link to the eval software user guide, and it discusses how to bring up the part in general:
My guess is that either the PLL isn't configured correctly and isn't locked, or that the SYNCb pin is low.
