Device Overview
PCI Express® switching solutions. The PES24N3A is a 24-lane, 3-port
peripheral chip that performs PCI Express packet switching with a
feature set optimized for high performance applications such as servers,
storage, and communications/networking. It provides connectivity and
switching functions between a PCI Express upstream port and two
downstream ports and supports switching between downstream ports.
