Grounding and Decoupling
Figure 22 shows the recommended decoupling capacitors and
ground connections for the AD9807/AD9805. Notice that all of
the power and ground connections are common for the analog
and digital portions of the chip. T his would be the best way to
connect the device on a board containing a large number of
digital components. By treating the AD9807/AD9805 as an
analog component, the on-board digital circuitry is considered
“quiet digital” and the digital supply pins are connected to the
clean analog supply and analog ground plane. For this tech-
nique to work well, it is important that the digital supply pins be
well decoupled to the analog ground plane and that the digital
outputs of the AD9807/AD9805 are buffered to minimize the
digital drive current. T he buffers would be referred to the digital
supply and ground. T his scheme is preferable to tying the digital
portion of the AD9807/AD9805 to a noisy digital ground and
power plane, capacitively coupling noise to the analog circuitry
within the device. T he AD9807/AD9805 evaluation boards use
this grounding method, shown in Figures 26 and 27. If a
minimum amount of digital circuitry exists on the board, it is
possible that the power and ground connections of the AD9807
can be separated; be sure to maintain a single point connection
between the two ground planes at the AD9807/AD9805.
