POWER DISSIPATION
The AD9786 has seven power supply domains: two 3.3 V analog
domains (AVDD1 and AVDD2), two 2.5 V analog domains
(ADVDD and ACVDD), one 2.5 V clock domain (CLKVDD),
and two digital domains (DVDD, which runs from 2.5 V, and
DRVDD, which can run from 2.5 V or 3.3 V).
The current needed for the 3.3 V analog supplies, AVDD1 and
AVDD2, is consistent across speed and varying modes of the
AD9786.
Nominally, the current for AVDD1 is 29 mA across
all speeds and modes, while the current for AVDD2 is 20 mA.
The current for the 2.5 V analog supplies and the digital
supplies varies depending on speed and mode of operation.
Figure 67, Figure 68, and Figure 69 show this variation. Note
that CLKVDD, ADVDD, and ACVDD vary with clock speed
and interpolation rate, but not with modulation rate.
