I’m using AD9707 with AVDD=1.8V, CLKVDD=2.5V and DVDD=3.3V power supply according to data sheet that, at pag. 30, states:
“The analog and digital sections of the AD9704/AD9705/AD9706/AD9707 have separate power supply inputs (AVDD and DVDD) that can operate independently over a 1.7 V to 3.6 V range”
Unfortunately, in my design, the AD9707 outputs current from AVDD corrupting the 1.8V supply and rising it up to 2.7V. I already checked that the 1.8V regulator works well with AD9707 disconnected.
Can you confirm that the AVDD,DVDD and CLKVDD I’m using is correct?
