IDT™ 89HPES16T4 PCI Express® Switch User Manual April 2008
● The 89HPES16T4 is a member of the IDT PRECISE™ family of PCI Express® switching solutions. The PES16T4 is a 16-lane, 4-port peripheral chip that performs PCI Express packet switching with a feature set optimized for high performance applications such as servers, storage, and communications/networking. It provides connectivity and switching functions between a PCI Express upstream port and up to three down stream ports and supports switching between downstream ports.
● Utilizing standard PCI Express interconnect, the PES16T4 provides 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 4 ports across 16 integrated serial lanes. Each lane provides 2.5 Gbps of bandwidth in both directions and is fully compliant with PCI Express Base specification revision 1.1.
● The PES16T4 is based on a flexible and efficient layered architecture. The PCI Express layers consist of SerDes, Physical, Data Link and Transaction layers. The PES16T4 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.
