• Manufacturer Part Number: 89hpes32t8
• Description: 32-lane, 8-port Pcie I/o Expansion Switch
• Manufacturer: Integrated Device Technology

Product Description
the most efficient I/O connectivity solution for applications requiring high
throughput, low latency, and simple board layout with a minimum
number of board layers. It provides connectivity for up to 8 ports across
32 integrated serial lanes. Each lane provides 2.5 Gbps of bandwidth in
both directions and is fully compliant with PCI Express Base specifica-
tion revision 1.1.

ture. The PCI Express layers consist of SerDes, Physical, Data Link and
Transaction layers. The PES32T8 can operate either as a store and
forward switch or a cut-through switch and is designed to switch
memory and I/O transactions. It supports eight Traffic Classes (TCs)
and one Virtual Channel (VC) with sophisticated resource management
to enable efficient switching and I/O connectivity.
The PES32T8 is based on a flexible and efficient layered architec-
