AD9951 EVAL BOARD OUTPUT VOLTAGE SWING

Hi,

 

I am using AD9954 eval board. I program this for 136MHz. Power level on the spectrum analyser is -7dBm.

1. Can you tell me the equivalent voltage (peak value) of the output waveform? Is it approximately 140mV?

2. AVDD and DVDD are connected to 1.8V and DVDD_IO to 3.3V. Can I get an output of 1.8V peak( after transformer and filter)? 

Any help would be greatly appreciated

regards 

Rekha
