89HPES32T8G2 Datasheet | Renesas

Overview The 89HPES32T8G2 is a member of the IDT PRECISE™ family of PCI Express® switching solutions. The PES32T8G2 is a 32-lane, 8-port switch optimized for PCI Express Gen2 packet switching in high-performance applications. Target applications include servers, storage, munications, embedded systems, and multi-host or intelligent I/O based systems with inter-domain munication. Features - High Performance Non-Blocking Switch Architecture - 32-lane 8-port PCIe switch - Four x8 switch ports each of which can bifurcate to two x4 ports (total of eight x4 ports) - Integrated Ser Des supports 5.0 GT/s Gen2 and 2.5 GT/s Gen1 operation - Delivers up to 32 GBps (256 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 - Port Configurability - x4 and x8 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 - Initialization / Configuration - Supports Root (BIOS, OS, or driver), Serial EEPROM, or SMBus switch initialization - mon switch configurations are supported with pin strapping (no external ponents) - Supports in-system Serial EEPROM initialization/programming...
