3 ways Linear Redrivers for PCIe 3.0 differ from ReDrivers

Designers know that redrivers are an essential part of solving signal integrity challenges in gigabit systems. But at speeds up to 8 GT/s in PCI Express 3.0 systems, linear redrivers are needed to also comply with PCI-SIG specs and with chipset vendors’ datasheets. That is, it’s not enough to open the signal eye—the redriver also needs to precisely match PCI Express Link Training waveforms while offering designers the ability to “tweak” channel characteristics.
