Application Information

Design Considerations

DUT On vs. DUT Off

Many HDMI CTS tests require a power off condition on

the System Under Test. Many discrete ESD diode

configurations can be forward baised when their VDD

rail is lower than the I/O pin bias, thereby exhibiting

extremely high apparent capacitance measurements,

for example. The MediaGuardΤΜ backdrive isolation

circuitry limits this current to less than 5μA, and will

help ensure HDMI compliance.
