For example there are AEC-Q100 qualified signal repeater chips, which it brands ‘ReDrivers’, for longer USB 3.0 and PCIe cables. ReDrivers compensate for signal distortion, but do not digitally re-time signals – take a look at this Pericom video.
As well, “PI7C9X2G308GP is the industry’s only PCIe 2.0 packet switch that supports x4 upstream to 2 x2 ports downstream, and AECQ 3-Port / 4-Lane packet switch for infotainment applications,” claimed Pericom.
There are also PCIe 2.0 packet switches with integrated clock buffers, and what is claimed to industry’s only AEC-Q100 qualified 100MHz PCIe clock generators – aimed at automotive infotainment.
