89HPES24NT6AG2 Datasheet | Renesas

Overview The 89HPES24NT6AG2 is a member of the IDT family of PCI Express® switching solutions. The PES24NT6AG2 is a 24-lane, 6-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 - 24-lane, 6-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 24 GBps (192 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 - Six x4 ports - Automatic per port link width negotiation (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 6 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 6 NT endpoints per switch, each endpoint can municate with other switch partitions or external PCIe domains or CPUs - 6 BARs per NT Endpoint - Bar address translation - All BARs support 32/64-bit base and limit address translation - Two BARs (BAR2 and BAR4) support look-up table based address translation - 32 inbound and outbound doorbell registers - 4 inbound and outbound message registers -...
