I have my AD9857 with the next configuration:
I am using AD9857 with a single REFCLK input of 146.2857MHz with very good CMOS levels.(i have diffclken connected to gnd)
I have a 2K resistor in pin RSET.
Iout = 39.93/RSET, So Iout level should be 20mA (13dBm) .... my output level is lower around -60dBm,
i really dont know how to fix it. Thanks.
