ADV3003

TMDS Terminations
In a typical application, all pins labeled AVEE, including the
ePAD, should be connected directly to ground. All pins labeled
AVCC, VTTI, or VTTO should be connected to 3.3 V. The
supplies can also be powered individually, but care must be
taken to ensure that each stage of the ADV3003 is powered
correctly.
The ADV3003 provides internal 50 Ω single-ended
terminations for all its high speed inputs and outputs.
The output termination resistors are always enabled and act
to back-terminate the output TMDS transmission lines. These
back-terminations act to absorb reflections from impedance
discontinuities on the output traces, improving the signal
integrity of the output traces and adding flexibility to how the
output traces can be routed. For example, interlayer vias can be
used to route the ADV3003 TMDS outputs on multiple layers of
the PCB without severely degrading the quality of the output
signal.
Power Supply Bypassing
The ADV3003 requires minimal supply bypassing. When
powering the supplies individually, place a 0.01 μF capacitor
between each 3.3 V supply pin (AVCC, 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
In a typical application, the ADV3003 output is connected to an
HDMI/DVI receiver or another device with a 50 Ω single-ended
input termination. It is recommended that the outputs be
terminated with external 50 Ω on-board resistors when the
ADV3003 is not connected to another device.

Auxiliary Control Signals
There are four low-speed, single-ended control signals asso-
ciated with each source or sink in an HDMI/DVI application.
These control signals are hot plug detect (HPD), consumer
electronics control (CEC), and two display data channel (DDC)
lines. The two signals on the DDC bus are serial data and serial
clock (SDA and SCL, respectively). The ADV3003, which is a
TMDS-only part, does not buffer these low speed signals. If the
end application requires it, use other means to buffer these
signals.

Power Supplies
In applications where the ADV3003 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
ADV3003.
The ADV3003 has three separate power supplies referenced
to a single ground, AVEE. The supply/ground pairs are as
follows: AVCC/AVEE, VTTI/AVEE, and VTTO/AVEE.
The AVCC/AVEE supply (3.3 V) powers the core of the
ADV3003. The VTTI/AVEE supply (3.3 V) powers the input
termination (see Figure 25). Similarly, the VTTO/AVEE supply
(3.3 V) powers the output termination (see Figure 26).
