I'm using a DAC38J84EVM with a TSW14J56EVM and their included software GUI. I get nice looking sine waves with various lane rates, clock speeds etc. But I always get "DAC PLL Out of Lock" and "SERDES PLL 1 Out of Lock" alarms. There are also alarms on Lanes 4 to 7, which is odd since they are not in use. It does not matter how many times I clear the alarms.
This is odd since the DAC PLL is driven by the onboard LMK04828.
Any ideas?
