Power Supply Bypassing
The ADV3000 requires minimal supply bypassing. When
powering the supplies individually, place a 0.01 μF capacitor
between each 3.3 V supply pin (AVCC, DVCC, VTTI, and VTTO)
and ground to filter out supply noise. Generally, bypass capacitors
should be placed near the power pins and should connect directly
to the relevant supplies (without long intervening traces). For
example, to improve the parasitic inductance of the power supply
decoupling capacitors, minimize the trace length between
capacitor landing pads and the vias as shown in Figure 34.
In applications where the ADV3000 is powered by a single 3.3 V
supply, it is recommended to use two reference supply planes

and bypass the 3.3 V reference plane to the ground reference
plane with one 220 pF, one 1000 pF, two 0.01 μF, and one 4.7 μF
capacitors. The capacitors should via down directly to the
supply planes and be placed within a few centimeters of the
ADV3000. The AMUXVCC supply does not require additional
bypassing. This bypassing scheme is illustrated in Figure 35.
