DAC3482EVM: DAC3482EVM CDCE62005 PLL problem

Part Number: DAC3482EVM
Other Parts Discussed in Thread: CDCE62005


I have DAC3482EVM. I'm trying to configure the CDCE62005 integrated on the board. Although I do the same configuration, I see my clock signal, which should normally be set to 64Mhz, at different frequencies each time. I am using auto calibration but it is not working. can you help me please ?
