? 2014 littelfuse, inc. specifcations are subject to change without notice. revised: 08/21/14 application information adding external esd protection to a high-speed data port is not trivial for a variety of reasons. 1. esd protection devices will add parasitic capacitance to each data line from line to gnd and line to line causing impedance mismatches between the differential pairs. this ultimately affects the signal eye-diagram and whether or not the transceiver can distinguish a 1 from a 0. 2. esd devices should be placed as close as possible to the port being protected to maximize their effect (i.e. clamping capability) and minimize the effect that pcb trace inductance can have during an esd transient. depending on the package size and pinout this could be challenging and the bigger the package, the larger the land pattern must be, which adds more parasitic capacitance. 3. stub traces can add another element of discontinuity adversely affecting signal integrity so esd protection is best employed when its overlaid on the data lines or when the signals can simply pass underneath the device. taking all of this into account littelfuse developed the SP3012 series which was designed specifcally for protection of high-speed data ports such as hdmi 1.3/1.4 and usb 3.0. they present less than 0.5pf from line to gnd and only 0.3pf from line to line minimizing impedance mismatch between the differential pairs. furthermore, the SP3012 is rated up to 12kv (contact discharge) which far exceeds the maximum requirement of the iec 61000-4-2 standard. there are two options available (4 channel and 6 channel) and both are housed in leadless dfn packages so the data lines can pass directly underneath the device to reduce discontinuities and maintain signal integrity. j1 u1 figure 1 shows the layout used for the SP3012-06utg in a usb 3.0 application. the traces routed toward the top are the two legacy usb 2.0 lines (d+/d-) that run at the slower speed of 480mbps and therefore are not as critical as the 5gbps super-speed traces. figure 1: pcb layout of the SP3012-06utg for usb 3.0 figure 2: usb 3.0 eye diagram with the SP3012-06utg figure 3: usb 3.0 eye diagram with the SP3012-04utg figure 2 shows the usb 3.0 eye diagram that resulted from the pcb layout above with the SP3012-06utg soldered on the landing pattern. b ase: 27 .0000 ns scale:33.0 ps/div 50 0 0 -50 0 wfrms:500 using a similar layout as above, figure 3 shows the eye diagram that resulted using the SP3012-04utg to protect the super-speed data lines and the sp3003-02utg to protect the legacy data pair. b ase: 27 .0000 ns scale:33.0 ps/div 50 0 0 -50 0 wfrms:850 signal integrity of high-speed data interfaces usb 3.0 eye diagram data tvs diode arrays (spa ? diodes) low capacitance esd protection - SP3012 series
