Overview: .. 12-lane 3-Port Non-Transparent PCI Express® Switch
® 89HPES12NT3 Data Sheet
Preliminary Information* Device Overview
The 89HPES12NT3 is a member of the IDT PRECISE™ family of PCI Express® switching solutions offering the next-generation I/O interconnect standard. The PES12NT3 is a 12-lane, 3-port peripheral chip that performs PCI Express Base switching with a feature set optimized for high performance applications such as servers, storage, and munications/networking. It provides high-performance I/O connectivity and switching functions between a PCIe® upstream port, a transparent downstream port, and a non-transparent downstream port. With non-transparent bridging (NTB) functionality, the PES12NT3 can be used standalone or as a chipset with IDT PCIe System Interconnect Switches in multi-host and intelligent I/O applications such as munications, storage, and blade servers where inter-domain munication is required.
