PCIe Gen2 (Gen3 is still ramping up) is about as common on digital PCBs as is a terminal block or pin header. Nearly every CPU, MCU, fast peripheral, bus or nonvolatile (NV) memory sports PCIe. To connect all of these “dots” together requires a PCI Express switch or one of the creative variations thereof.
From PCIe to HDMI to DDR3, good quality signal switches can route your data and simplify designs—if you know how to use them.
