It's the part you find on a dead server backplane when the link training fails on Gen 5 lanes — the input equalisation stage is the first thing to check with a scope. The 4 x 2:2 crosspoint means four upstream lanes can be fanned out to two downstream ports each, common in PCIe bifurcation or M.2 slot redrives. ## 1.6 pF input capacitance — why it matters at 32 Gbps Input capacitance sits at 1.6 pF, low enough that it doesn't collapse the upstream transmitter's eye opening at 32 Gbps. If you're swapping in a redriver from a different family and the eye margin drops, this capacitance figure is the first suspect — a 2 pF part will close the mask on a marginal layout. The 0.1 ns propagation delay keeps the lane-to-lane skew tight enough for PCIe Gen 5 timing budgets. ## Package and supply rail — layout checklist Housed in a 64-WFQFN exposed-pad package (5.5 x 10 mm body), surface-mount only. Supply range is 3 V to 3.6 V — a clean 3.3 V rail with adequate decoupling at the exposed pad is the rule.","metaTitle":"TI DS320PR822NJXT PCIe 5.0 ReDriver, 32 Gbps, 8-Channel","metaDescription":"TI DS320PR822NJXT PCIe 5.0 eight-channel ReDriver. 32 Gbps data rate, 4 x 2:2 crosspoint, 1.6 pF input capacitance.
