Overview
5-Lane 5-Port PCI Express® Switch ® 89PES5T5 Data Sheet Device Overview The 89HPES5T5 is a member of IDT’s PRECISE™ family of PCI Express switching solutions.
The PES5T5 is an 5-lane, 5-port peripheral chip that performs PCI Express Base switching.
It provides connectivity and switching functions between a PCI Express upstream port and up to four downstream ports and supports switching between downstream ports.
