PESD2V8Y1BSF and PESD4V0Y1BCSF from Nexperia are Electrostatic Discharge (ESD) safety gadgets optimized to be used with retimers and redrivers on high-speed knowledge traces. Retimers and redrivers are generally used within the design of high-speed USB4 interfaces. Nevertheless, these lead to shorter board traces which have a decrease parasitic inductance, an unintended consequence of which is a discount within the general system-level ESD robustness. The PESD2V8Y1BSF is designed to guard USB4 (Thunderbolt) interfaces, whereas, PESD4V0Y1BCSF can defend each the USB4 in addition to the HDMI 2.1 interface. The part employs Nexperia’s TrEOS expertise, which mixes low clamping with low capacitance and excessive robustness. Each the gadgets provide a backward compatibility
In accordance with the corporate, the PESD2V8Y1BSF and PESD4V0Y1BCSF could be positioned instantly subsequent to the system which is to be protected, this allows the gadgets to supply larger design flexibility in comparison with most different ESD safety gadgets, furthermore, the AC coupling capacitance is protected as effectively. On prime, it locations many of the line inductance between ESD safety and guarded system to optimize system ESD efficiency.
“Nexperia allows design engineers to satisfy tight budgets on each insertion and return loss for prime velocity USB4 knowledge traces by offering gadgets that decrease the affect of ESD safety on general system price range,” says Stefan Seider, senior product supervisor at Nexperia. “These gadgets provide the optimum stability between optimizing system-level ESD robustness and RF efficiency.”
The corporate claims that so as to keep backward compatibility with older interface requirements like USB3.2, which could be linked over USB Kind-C, the PESD2V8Y1BSF has a reverse standoff voltage, VRWM = 2.8 V, whereas the PESD4V0Y1BCSF has a VRWM = 4 V making it appropriate for HDMI 2.1 as effectively. The RF efficiency of the TrEOS expertise used for each gadgets doesn’t degrade over the working voltage vary. Other than USB4 and HDMI 2.1, each elements will also be used to guard PCIe or DisplayPort interfaces.
