In this series we are going to discuss board layout recommendations for the peripheral component interconnect express or PCle. PCIe is a high-performance interconnect that enables high bandwidth, scalable, error detection, and hot-swap functionality across multiple clock boundaries. To accommodate high bandwidth and scalability, multiple traces carrying high-speed data at 16Gbps or higher are used. These high-speed lanes require special considering when designing a PCB layout.
