89HPES16NT16G2 Datasheet | Renesas

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 munication is required, such as servers, storage, munications, and embedded systems. Features - High Performance Non-Blocking Switch Architecture - 16-lane, 16-port PCIe switch with flexible port configuration - Integrated Ser Des 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 binations 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 Ser Des 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)...
