The ADV3003 has an external control pin, TX_EN. The
TX_EN pin must be connected to either a logic high (1) or
low (0), in accordance with the logic values set forth in Table 1.
The use of the TX_EN pin is described in Table 5. When the
transmitter is enabled by setting TX_EN to 1, both the input
and output terminations are enabled. Setting TX_EN to 0
disables the transmitter, reducing power when the transmitter
is not in use. When the transmitter is disabled, the input termi-
nation resistors are also disabled to present a high impedance
state at the input and indicate to any connected HDMI sources
that the link through the ADV3003 is inactive.

The ADV3003 also includes two levels of programmable output
pre-emphasis, 0 dB and 6 dB. The output pre-emphasis level can
be manually configured by setting the PE_EN pin. The PE_EN
pin must be connected to either a logic high (1) or low (0), in
accordance with the logic values set forth in Table 1. The use of
the PE_EN pin is described in Table 6. No specific cable length
is suggested for use with either pre-emphasis setting, because
cable performance varies widely among manufacturers.

In a typical application, the output of the ADV3003 is
connected to the input of an HDMI/DVI receiver, which
provides a second set of matched terminations in accordance
with the HDMI 1.3 specification. If neither receiver nor receiver
termination is connected to the output of the ADV3003 in the
end-application, each ADV3003 output pin should be tied to 3.3
V through a 50 Ω resistor.
