PCIe 4.0 is the preferred serial interface for high-performance IT equipment including desktop and laptop PCs and workstations, and for use in embedded systems. As microprocessor manufacturers continue to push the performance envelope in serial bus speeds, differential ReDrivers are essential in applications that need to implement longer PCB trace lengths without introducing additional signal latency. The PI3EQX16612 and PI3EQX16621 offer four channels in a single package at speeds of up to 16Gbps per channel. This combination supports the routing of high-speed serial interfaces across motherboards where longer signal traces are needed to mitigate the effect of more densely populated cards. With full backwards-compatibility to PCIe 1.0, the devices offer an adjustable output linear swing, flat gain and equalization, all of which are configurable through pin strapping. These features allow design optimization to reduce intersymbol interference across a range of different physical mediums without the need for firmware configuration.
