Device Overview
The PES12N3, a 12 lane 3-port PCI Express® switch, is a member
of IDT’s PRECISE™ family of PCI Express switching solutions. The
PES12N3 is a peripheral chip that performs PCI Express Base switching
with a feature set optimized for high performance applications such as
servers and storage. It provides connectivity and switching functions
between a PCI Express upstream port and two downstream ports or
peer-to-peer switching between downstream ports.
Features
◆
High Performance PCI Express Switch
– Three x4 ports with 12 PCI lanes total
– Delivers 6 GBps (48 Gbps) aggregate switching capacity
– Low latency cut-through switch architecture
– Supports 128 to 256 byte maximum payload size
– Supports one virtual channel
– PCI Express Base specification Revision 1.0a compliant
◆
Flexible Architecture with Numerous Configuration Options
– Port arbitration schemes utilizing round robin or weighted
round robin algorithms
– Supports automatic per port link with negotiation (x4, x2, or x1)
– Supports static lane reversal on all ports
– Supports polarity inversion
– Supports locked transactions, allowing use with legacy soft-
ware
– Ability to load device configuration from serial EEPROM
