Description
Utilizing standard PCI Express interconnect, the PES48T12G2
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 48 GBps (384 Gbps) of aggregated,
full-duplex switching capacity through 48 integrated serial lanes, using
proven and robust IDT technology. Each lane provides 5 Gbps of bandwidth
in both directions and is fully compliant with PCI Express Base
Specification, Revision 2.0.
The PES48T12G2 is based on a flexible and efficient layered architecture.
The PCI Express layer consists of SerDes, Physical, Data Link
and Transaction layers in compliance with PCI Express Base specification
Revision 2.0. The PES48T12G2 can operate either as a store and
forward or cut-through switch. It supports eight Traffic Classes (TCs)
and one Virtual Channel (VC) with sophisticated resource management
to enable efficient switching and I/O connectivity for servers, storage,
and embedded processors with limited connectivity.
