Hi,

I have the same symptoms which [are described in this thread]. How did you solve this problem?

Since my CDCE72010 is on a commercial board and the example program works, i don't think its a

circuit problem.

Thank you in advanced.

Hello Alexander,

can you please some more info about your specific usage of the CDCE72010?

Please crosscheck that all configuration pins (!RESET, !PD, MODE_SEL ...) have correct levels applied and that the power has already settled within the operating conditions.

Please ensure that the timing requirements are met at the device pins mentioned in the datasheet (RECOMMENDED OPERATING CONDITIONS & Table 5).

You can use the EVM as a reference for your debug.

Best regards,

Patrick
