MAX3814
Laptop PC TMDS Equalizer and Driver
As shown at location XX in Figure 6b, the MAX3814
equalizes trace losses and redrives the TMDS outputs
at the docking connector. The 200
Ω resistor at the out-
put of the MAX3814 absorbs reflections from the dock-
ing connector.
Dock or Port Expander
The MAX3814 can also be used on the dock or port
expander as it equalizes loss, isolates the connector,
and redrives TMDS output signals at location YY as
shown in Figure 6b. Similarly, with the previous applica-
tion, the 200
Ω resistor at the output of the MAX3814
absorbs reflections in this case from the DVI or the
HDMI connector.
An optional 2dB to 6dB attenuator pad can be used to
absorb reflections between internal interface connec-
tions. If used, the attenuator pad must be a matched Pi
or T attenuator network. The resulting flat through loss
can be made by the excellent input sensitivity of the
MAX3814 as shown in the
Typical Application Circuits.
The MAX3814’s excellent input sensitivity allows the
attenuated signal to be restored.
