Product Description
Utilizing standard PCI Express interconnect, the PES24T6 provides
the most efficient fan-out solution for applications requiring high
throughput, low latency, and simple board layout with a minimum
number of board layers. It provides 12 GBps (96 Gbps) of aggregated,
full-duplex switching capacity through 24 integrated serial lanes, using
proven and robust IDT technology. Each lane provides 2.5 Gbps of
bandwidth in both directions and is fully compliant with PCI Express
Base specification 1.1.
The PES24T6 is based on a flexible and efficient layered architec-
ture. The PCI Express layers consist of SerDes, Physical, Data Link and
Transaction layers. The PES24T6 can operate either as a store and
forward or 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 effi-
cient switching and I/O connectivity.
