ADV3002
Data Sheet
Rev. B | Page 12 of 28
THEORY OF OPERATION
The primary function of the ADV3002 is to switch up to four
HDMI/DVI sources to one HDMI/DVI sink. Each HDMI/DVI
link consists of four differential, high speed channels and four
auxiliary single-ended, low speed signals. The high speed channels
include a data-word clock and three TMDS data channels running
at 10× the data-word clock frequency for data rates up to 2.25
Gbps. The four low speed control signals are the display data
channel (DDC) bus (SDA and SCL), the consumer electronics
control (CEC) line, and the hot plug detect (HPD) signal.
The ADV3002 also includes an integrated EDID SRAM,
eliminating the need for an external EDID EEPROM for each
HDMI connector. A typical HDMI multiplexer is shown in
Figure 23. The simplified implementation using the ADV3002
is shown in Figure 24.

Figure 24. Simplified Implementation Using the ADV3002
TMDS INPUT CHANNELS
Each high speed input differential pair terminates to the 3.3 V
power supply through a pair of 50 on-chip resistors, as shown
in Figure 25. The state of the input terminations can be configured
automatically or programmed manually by setting the appropriate
bits in the TMDS input termination control register, as shown
The input equalizer can be manually configured to provide
two different levels of high frequency boost: 4 dB or 16 dB for
2.25 Gbps data. The equalizer (EQ) level defaults to 16 dB after
reset. No specific cable length is suggested for a particular
equalization setting because cable performance varies widely
between manufacturers; however, in general, the equalization of
the ADV3002 can be set to 16 dB without degrading the signal
integrity, even for short input cables.

TMDS OUTPUT CHANNELS
Each high speed output differential pair is terminated to the 3.3 V
power supply through a pair of 50 on-chip resistors, as shown
in Figure 26. This termination is user-selectable; it can be
turned on or off by programming the TX_OTO bit of the TMDS
output control register, as shown in Table 10.

Figure 26. High Speed Output Simplified Schematic
The output termination resistors of the ADV3002 back
terminate the output TMDS transmission lines. These back
terminations, as recommended in the HDMI 1.4 specification,
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.
