Devic e Overview
The 89HPES24N3A is a member of the IDT PRECISE famly of
PCI Expressswitching solutions offering the next-generation I/O inter-
connect standard. The PES24N3A is a 24-lane, 3-port peripheral chip
that performs PCI Express Packet switching with a feature set optimzed
for high performance applications such as servers, storage, and commu-
nications/networking. It provides high-performance I/O connectivity and
switching functions between a PCI Express upstreamport and two
downstreamports or peer-to-peer switching between downstreamports.
The 89HPES24N3A offers an enhanced architecture and feature set
in a package that is pin-compatible with the first generation
89HPES24N3 24-lane, 3-port PCIe switch.
