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.

Features

◆ High Performance PCI Express Switch

– Twelve switch 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
