Data Sheet  
48-Lane 12-Port  
PCI Express® Switch  
®
–
–
Supports one virtual channel and eight traffic classes  
PCI Express Base Specification Revision 1.1 compliant  
Device Overview  
The 89HPES48T12 is a member of the IDT PRECISE™ family of  
PCI Express® switching solutions. The PES48T12 is a 48-lane, 12-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 up to  
eleven downstream ports and supports switching between downstream  
ports.  
◆
Flexible Architecture with Numerous Configuration Options  
–
–
–
–
–
Port arbitration schemes utilizing round robin algorithms  
Automatic per port link width negotiation to x8, x4, x2 or x1  
Automatic lane reversal on all ports  
Automatic polarity inversion on all lanes  
Supports locked transactions, allowing use with legacy soft-  
ware  
–
–
Ability to load device configuration from serial EEPROM  
Ability to control device via SMBus  
Features  
◆
High Performance PCI Express Switch  
◆
Highly Integrated Solution  
–
Twelve switch ports  
–
–
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)  
• 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  
◆
Reliability, Availability, and Serviceability (RAS) Features  
–
