89HPES12NT3  
Data Sheet  
Preliminary Information*  
12-lane 3-Port Non-Transparent  
PCI Express® Switch  
®
◆
Flexible Architecture with Numerous Configuration Options  
Device Overview  
–
–
Port arbitration schemes utilizing round robin  
Supports automatic per port link width negotiation (x4, x2, or  
x1)  
The 89HPES12NT3 is a member of the IDT PRECISE™ family of  
PCI Express® switching solutions offering the next-generation I/O inter-  
connect standard. The PES12NT3 is a 12-lane, 3-port peripheral chip  
that performs PCI Express Base switching with a feature set optimized  
for high performance applications such as servers, storage, and commu-  
nications/networking. It provides high-performance I/O connectivity and  
switching functions between a PCIe® upstream port, a transparent  
downstream port, and a non-transparent downstream port.  
–
–
–
Static 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  
◆
Non-Transparent Port  
With non-transparent bridging (NTB) functionality, the PES12NT3  
can be used standalone or as a chipset with IDT PCIe System Intercon-  
nect Switches in multi-host and intelligent I/O applications such as  
communications, storage, and blade servers where inter-domain  
communication is required.  
–
–
Crosslink support on NTB port  
Four mapping windows supported  
• Each may be configured as a 32-bit memory or I/O window  
• May be paired to form a 64-bit memory window  
Interprocessor communication  
–
• Thirty-two inbound and outbound doorbells  
• Four inbound and outbound message registers  
• Two shared scratchpad registers  
Allows up to sixteen masters to communicate through the non-  
transparent port  
No limit on the number of supported outstanding transactions  
through the non-transparent bridge  
Completely symmetric non-transparent bridge operation  
allows similar/same configuration software to be run  
Supports direct connection to a transparent or non-transparent  
port of another switch
