89HPES24N3A  
Data Sheet  
24-Lane 3-Port  
PCI Express® Switch  
®
Flexible Architecture with Numerous Configuration Options  
Device Overview  
Automatic per port link width negotiation to x8, x4, x2 or x1  
Automatic lane reversal on all ports  
Automatic polarity inversion on all lanes  
The 89HPES24N3A is a member of the IDT PRECISE™ family of  
PCI Express® switching solutions. The PES24N3A is a 24-lane, 3-port  
peripheral chip that performs PCI Express packet switching with a  
feature set optimized for high performance applications such as servers,  
storage, and communications/networking. It provides connectivity and  
switching functions between a PCI Express upstream port and two  
downstream ports and supports switching between downstream ports.  
Ability to load device configuration from serial EEPROM  
Legacy Support  
PCI compatible INTx emulation  
Bus locking  
Highly Integrated Solution  
Features  
Requires no external components  
Incorporates on-chip internal memory for packet buffering and  
queueing  
Integrates twenty-four 2.5 Gbps embedded SerDes with 8B/  
10B encoder/decoder (no separate transceivers needed)  
High Performance PCI Express Switch  
Twenty-four 2.5 Gbps PCI Express lanes  
Three switch ports  
Upstream port configurable up to x8  
Downstream ports configurable up to x8  
Low-latency cut-through switch architecture  
Support for Max Payload Size up to 2048 bytes  
One virtual channel  
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  
Compatible with Hot-Plug I/O expanders used on PC and  
server motherboards  
Eight traffic classes  
PCI Express Base Specification Revision 1.1 compliant
