It accepts differential input and delivers a differential output, applying input equalization to compensate for channel loss in high-speed serial interconnects. Typical deployment is on server motherboards, add-in cards, and backplane routing where trace lengths or connector losses exceed the PCIe eye budget. ## 16 Gbps per lane — what it means for the link The 16 Gbps data rate matches the PCIe Gen 4 lane rate exactly. At this speed, the 70 ps delay is a few unit intervals of latency — negligible for the link budget. The 250 mA supply draw at 1.7 V to 1.9 V is typical for a four-lane equalizer.","metaTitle":"PTN3944EWY PCIe Gen 4 Linear Equalizer, 16 Gbps","metaDescription":"PTN3944EWY PCIe Gen 4 linear equalizer, 16 Gbps, 4-channel, differential I/O, 36-HWFLGA.
