Eye-diagram testing, which involves repetitively sampling a digital signal and displaying the resulting eye pattern on an oscilloscope, is one way to characterize the effect of an ESD suppressor’s parasitic capacitance on signal integrity. A mask defines acceptable signal qualities and compliance, and in this case, demonstrates the SP3012-06UTG’s minimal impact on signal integrity. ESD protection for HDMI 1.3/1.4 and USB 3.0 chipsets The SP3012-06UTG delivers enhanced ESD protection with ultralow capacitance. Its extremely low dynamic resistance provides a clamping voltage that is 66% lower than competitive devices. The SP3012 is ideal for protecting high-speed applications, ensuring greater chipset reliability. Dramatic reduction in transient energy passed The clamping performance waveform shows the dramatic improvement made possible when a competitive diode array is replaced by a SP3012-06UTG. The area between the two curves indicates how much transient energy did not reach the chipset protected by the SP3012; this reduction in transient energy allows sensitive, small geometry chipsets to survive severe ESD events.
