The global appetite for data shows no sign of abating and continues to place pressure on service providers to handle more bits, more quickly.
Move over CANbus, PCI Express is the latest communications technology found in automotive infotainment.
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.
