Devic e Overview
The 89HPES48H12 is a member of the IDT PRECISE famly of
PCI Expressswitching solutions. The PES48H12 is a 48-lane, 12-port
systeminterconnect switch optimzed for PCI Express packet switching
in high-performance applications, supporting multiple simultaneous
peer-to-peer traffic flows. Target applications include servers, storage,
communications, and embedded systems.
Features
High Performance PCI Express Switch
–
Twelve maximumswitch ports
Six main ports each of which consists of 8 SerDes
Each x8 main port can further bifurcate to 2 x4-ports
–
Forty-eight 2.5 Gbps embedded SerDes
Supports pre-emphasis and receive equalization on per-port
basis
–
Delivers 192 Gbps (24 GBps) of 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
–
Supports automatic lane reversal on all ports
–

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 forty-eight 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
–
Supports optional PCI Express end-to-end CRC checking
–
Internal end-to-end parity protection on all TLPs ensures data
integrity even in systems that do not implement end-to-end
CRC (ECRC)
