LMX2595: Output signal is not clean/noisy

Part Number: LMX2595

Hi, 

I have designed a board that incorporates a LMX2595 using a 10MHz reference signal and the output should be 11.1GHz.

The board was designed using the EVM board as reference, some components which I believed to be unnecessary have been removed for ease of manufacturer. 

However, the output seems to be really noisy and just in general not a nice clean output.

I have attached the output signal, taken from a spec an and also attached the schematic. 

If needed I can attach the register file, however, the same code has been uploaded to the EVM board and the output is clean. 

Many thanks
