Hot-selling and scarce 89HPES12NT3ZBBCG 12-lane 3-Port Non-Transparent PCI Express® Switch BGA spot stock

Product Descriptions

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 communications/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 communications,  storage,  and  blade  servers  where  inter-domain communication is required.
