89HPES16T7 Datasheet | IDT

Overview - The 89HPES16T7 is a member of the IDT PRECISE™ family of PCI Express switching solutions. The PES16T7 is a 16-lane, 7-port 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 seven downstream ports and supports switching between downstream ports. - - Features - - High Performance PCI Express Switch - Sixteen 2.5 Gbps PCI Express lanes - Seven switch ports - Upstream port configurable up to x8 - Two downstream ports configurable up to x4, four downstream ports are x1 - Low-latency cut-through switch architecture - Support for Max Payload Sizes up to 2048 bytes - One virtual channel - Eight traffic classes - PCI Express Base Specification Revision 1.1 pliant Flexible Architecture with Numerous Configuration Options - Automatic per port link width negotiation to x8, x4, x2 or x1 - Automatic lane reversal on all ports - Automatic polarity inversion on all lanes - Ability to load device configuration from serial EEPROM - Legacy Support - PCI patible INTx emulation - Bus locking Highly Integrated Solution - Requires no external ponents - Incorporates on-chip internal memory for packet buffering and queueing - Integrates sixteen 2.5 Gbps embedded Ser Des with 8B/10B encoder/decoder (no separate transceivers needed) Reliability, Availability, and Serviceability (RAS) Features - Supports ECRC and Advanced Error Reporting - Internal end-to-end parity protection on all TLPs ensures data integrity even in systems that do not implement end-to-end CRC (ECRC) - Supports PCI Express Native Hot-Plug, Hot-Swap capable I/O - patible with Hot-Plug I/O expanders used on PC and server motherboards Power Management - Utilizes advanced low-power design techniques to achieve low typical power consumption - Supports PCI Power Management Interface...
