I cannot find the consumption for ad9520 lpvecl outputs. My question is:
if I configure all 12 differential outputs as LVPECL, how much current the chip will draw from VS_DRV pins?
It depends on the size of the external pull-downs.
Let's say you use 200 ohm pull-downs. You will have 24 of those (2 per driver), and 10 mA per pull-down. (2V/200ohm).
Therefore, you'll have 240 mA in the output drivers alone. 300 mA should be fine.
Thank you very much! I do use 200 ohm emitter resistors.
