SLLS852 – AUGUST 2007
The TMDS251 is powered up with two different power sources. One is 3.3-V VCC for the TMDS circuitry, and the
other is 5-V VDD for HPD, DDC, and most of the control logic. It is recommended to provide the same 3.3-V
power source to the TMDS circuitry of the TMDS251 and its output termination voltage. This minimizes the
leakage current from the ESD protection circuitry. When the digital television (DTV) is in standby mode operation,
the same common 3.3-V power source can be turned on or off. Either way will minimize the leakage current in
the device, and in the receiver connected at the output where the termination is integrated.
Selectable frequency response equalization circuitries are provided to all twelve differential input to support short
range and long range cable connections. The frequency response compensation curves and target cable losses
are shown in Figure 14 and Figure 15.
