TMDS (for HDMI and DVI)

Transition Minimized Differential Signaling (TMDS) is the electrical level standard used to transmit Digital Visual Interface (DVI) and High-Definition Multimedia Interface (HDMI) data.

Design Considerations

Intra-Pair Skew – The time difference between the true and complementary signals of a given differential pair should be kept as small as possible.

Residual Jitter – The difference in the amount of measured jitter between the test point and the signal source. It is the allowable maximum residual jitter is equivalent to the minimum jitter budget between transmitter and receiver.

ESD – External connectors being exposed to the outside world are especially susceptible to electrostatic discharge. A higher ESD rating provides improved protection.
