AD9915, poor output performance beyond 100MHz

Hello,

 

after setting up the AD9915 to function via parallel programming, I discovered, that the output signal of the chip is getting more noisy and is losing amplitude until it is not useable anymore at about 170 MHz. Up to 100 MHz I get a very clean sine wave with a 1.2 V-pp level. I am using my own board based on the EVAL-board.

Any help is very much appreciated. 

 

Kind Regards
