89HPES34H16G2 Datasheet | Renesas

Overview The 89HPES34H16G2 is a member of the IDT PRECISE™ family of PCI Express® switching solutions. The PES34H16G2 is a 34-lane, 16port peripheral chip that performs PCI Express packet switching with a feature set optimized for high-performance applications such as servers, storage, and munications/networking. It provides connectivity and switching functions between a PCI Express upstream port and up to fifteen downstream ports and supports switching between downstream ports. Features - High Performance Non-Blocking Switch Architecture - 34-lane 16-port PCIe switch - Three x8 switch ports each of which can bifurcate to two x4 ports (total of six x4 ports) - Ten x1 switch ports - Integrated Ser Des supports 5.0 GT/s Gen2 and 2.5 GT/s Gen1 operation - Delivers up to 34 GBps (272 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 - Standards and patibility - PCI Express Base Specification 2.0 pliant - Implements the following optional PCI Express features - Advanced Error Reporting (AER) on all ports - End-to-End CRC (ECRC) - Access Control Services (ACS) - Power Budgeting Enhanced Capability - Device Serial Number Enhanced Capability - Sub-System ID and Sub-System Vendor ID Capability - Internal Error Reporting ECN - Multicast ECN - VGA and ISA enable - L0s and L1 ASPM - ARI ECN - patible with IDT 89HPES34H16 PCIe Gen1 switch - Port Configurability - x8, x4, and x1 ports - Ability to merge adjacent x4 ports to create a x8 port - Automatic per port link width negotiation (x8 → x4 → x2 → x1) - Crosslink support - Automatic lane reversal - Autonomous and software managed link width and speed control - Per lane Ser Des configuration - De-emphasis - Receive equalization - Drive strength - Switch Partitioning - IDT proprietary feature that creates logically independent switches in the...
