While providing ESD protection with transient voltage suppression (TVS) diodes, the TVS protection adds little or no additional glitch in the high-speed differential signals. The high-speed transition minimized differential signaling (TMDS) ESD protection lines add only 0.8-pF capacitance. The low-speed control lines offer voltage-level shifting to eliminate the need for an external voltage levelshifter IC. The control line TVS diodes ad...
