Devic e Overview
The 89HPES12N3A, a 12 lane 3-port PCI Expressswitch, is a
member of the IDT PRECISE famly of PCI Express switching solu-
tions. The PES12N3A is a peripheral chip that performs PCI Express
Packet switching with a feature set optimzed for high performance
applications such as servers and storage. It provides connectivity and
switching functions between a PCI Express upstreamport and two
downstreamports or peer-to-peer switching between downstreamports.
The 89HPES12N3A offers an enhanced architecture and feature set
in a package that is pin-compatible with the first generation
89HPES12N3 12-lane, 3-port PCIe switch.
