Part Number: LMX2572EVM

We are working with the LMX2572, and we have been having the following issues:
1. When following the simple example given in the instructions (loading the default configuration), we see a peak not at 3GHz, but at about 2.75GHz. 
2. If we change RFoutA to 3200 MHz, we see no change in the output signal. 
3. The PLL lock status LED never illuminates, even after toggling FCAL_EN.
When we power down the unit using User Controls > POWERDOWN, we see the power drop.
