Overview
16-Lane 16-Port PCIe® Gen2 System Interconnect Switch ® 89HPES16NT16G2 Datasheet Device Overview The 89HPES16NT16G2 is a member of the IDT family of PCI Express® switching solutions.
The PES16NT16G2 is a 16-lane, 16-port system interconnect switch optimized for PCI Express Gen2 packet switching in high-performance applications, supporting multiple simultaneous peer-to-peer traffic flows.
Target applications include multi-host or intelligent I/O based systems where inter-domain communication is required, such as servers, storage, communications, and embedded systems.
Features  High Performance Non-Blocking Switch Architecture – 16-lane, 16-port PCIe switch with flexible port configuration – Integrated SerDes supports 5.
0 GT/s Gen2 and 2.
5 GT/s Gen1 operation – Delivers up to 16 GBps (128 Gbps) of switching capacity – Supports 128 Bytes to 2 KB maximum payload size – Low latency cut-through architecture – Supports one virtual channel and eight traffic classes  Port Configurability – Three stacks • One x8 port configurable as: • One x8 port • Two x4 ports • Four x2 ports • Eight x1 ports • Several combinations of the above lane widths • One x4 port configurable as: • One x4 port • Two x2 ports • 4 x1 ports • Four x1 ports – Automatic per port link width negotiation (x8  x4  x2  x1) – Crosslink support – Automatic lane reversal – Per lane SerDes configuration • De-emphasis • Receive equalization • Drive strength  Innovative Switch Partitioning Feature – Supports up to 4 fully independent switch partitions – Logically independent switches in the same device – Configurable downstream port device numbering – Supports dynamic reconfiguration of switch partitions • Dynamic port reconfiguration — downstream, upstream, non-transparent bridge • Dynamic migration of ports between partitions • Movable upstream port within and between switch partitions  Non-Transparent Bridging (NTB) Support – Supports up to 4 NT endpoints per switch, each endpoint can communicate with o...
