Utilizing standard PCI Express interconnect, the PES12T3G2 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. PES12T3G2 provides 12 GBps (96 Gbps) of aggregated, full-duplex switching capacity through 12 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 PES12T3G2 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 PES12T3G2 can operate either as a store and forward or cut-through switch and is designed to switch memory and I/O transactions. PES12T3G2 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.
