Manufacturer
Integrated Device Technology
Datasheet
Device Overview
PCI Express® switching solutions offering the next-generation I/O inter-
connect standard. The PES16NT2 is a 16-lane, 2-port peripheral chip
that provides high-performance switching and non-transparent bridging
(NTB) functions between a PCIe® upstream port and an NTB down-
stream port. The PES16NT2 is a part of the IDT PCIe System Intercon-
nect Products and is intended to be used with IDT PCIe System
Interconnect Switches. Together, the chipset targets multi-host and intel-
ligent I/O applications such as communications, storage, and blade
servers where inter-domain communication is required.

... IDT 89HPES16NT2 Data Sheet Pin Characteristics Note: Some input pads of the PES16NT2 do not contain internal pull-ups or pull-downs. Unused inputs should be tied off to appropriate levels. This is especially critical for unused control signal inputs which, if left floating, could adversely affect operation. Also, any input pin left floating can cause a slight increase in power consumption ...
