That matters when the channel runs through a backplane or a long PCB trace where the eye diagram would otherwise close. Supply range is 2.375 V to 3.6 V. The 200 ps propagation delay adds deterministic latency to the link budget. ## Industrial temperature and package Rated -40°C to 85°C, the DS80PCI402SQ/NOPB suits outdoor telecom cabinets, factory-floor backplanes, and other environments where the ambient temperature swings. The 54-WQFN exposed pad needs a thermal via pattern under the package to pull heat into the PCB ground plane — standard practice for this footprint. Input capacitance is 10 pF per channel, which is typical for a redriver input stage and does not load the upstream transmitter beyond what the PCIe spec expects. ## Active production, no obsolescence concern No end-of-life notice, no last-time-buy window. For a BOM freeze or a new design, this part does not carry the supply-chain risk of a phased-out device.","metaTitle":"DS80PCI402SQ/NOPB PCIe Gen3 Redriver, 8-Ch, 8 Gbps, 54-WQFN","metaDescription":"TI DS80PCI402SQ/NOPB 8-channel PCIe Gen3 redriver, 8 Gbps per lane, 200 ps delay, -40°C to 85°C.
