Devic e Overview
The 89HPES32H8 is a member of the IDT PRECISE famly of PCI
Expressswitching solutions. The PES32H8 is a 32-lane, 8-port system
interconnect switch optimzed for PCI Express packet switching in high-
performance applications, supporting multiple simultaneous peer-to-
peer traffic flows. Target applications include servers, storage, communi-
cations, and embedded systems.
Features
◆
High Performance PCI Express Switch
–
Eight maximumswitch ports
Four main ports each of which consists of eight SerDes
Each x8 main port can further bifurcate to 2 x4-ports
–
Thirty-two 2.5 Gbps embedded SerDes
Supports pre-emphasis and receive equalization on per-port
basis
–
Delivers 128 Gbps (16 GBps) aggregate switching capacity
–
Low-latency cut-through switch architecture
–
Support for Max Payload Size up to 2048 bytes
–
Supports two virtual channels and eight traffic classes
–
PCI Express Base Specification Revision 1.1 compliant
◆
Flexible Architecture with Numerous Configuration Options
–
Port arbitration schemes utilizing round robin algorithms
–
Virtual channels arbitration based on priority
–
Automatic per port link width negotiation to x8, x4, x2 or x1
–
Automatic lane reversal on all ports
–
Automatic polarity inversion on all ports
–
Supports locked transactions, allowing use with legacy soft-
ware
–
Ability to load device configuration fromserial EEPROM
–
Ability to control device via SMBus
◆
Highly Integrated Solution
–
Requires no external components
–
Incorporates on-chip internal memory for packet buffering and
queueing
–
Integrates thirty-two 2.5 Gbps embedded full duplex SerDes,
8B/10B encoder/decoder (no separate transceivers needed)
◆
Reliability, Availability, and Serviceability (RAS) Features
–
Redundant upstreamport failover capability
–
Internal end-to-end parity protection on all TLPs ensures data
integrity even in systems that do not implement end-to-end
CRC (ECRC)
