Product Description
throughput, low latency, and simple board layout with a minimum number of board layers. It provides 3 GBps (24 Gbps) of aggregated, full-duplex
switching capacity through 6 integrated serial lanes, using proven and robust IDT technology. Each lane provides 2.5 Gbps of bandwidth in both direc-
tions and is fully compliant with PCI Express Base specification revision 1.1.
tion layers in compliance with PCI Express Base specification Revision 1.1. The PES6T5 can operate either as a store and forward or cut-through
switch and is designed to switch memory and I/O transactions. It supports eight Traffic Classes (TCs) and one Virtual Channel (VC) with sophisticated
resource management to allow efficient switching for applications requiring additional narrow port connectivity.
SMBus Interface
configuration register in the device to be read or written by an external agent. The master interface allows the default configuration register values of
the PES6T5 to be overridden following a reset with values programmed in an external serial EEPROM. The master interface is also used by an
external Hot-Plug I/O expander.
the slave interface, these address pins allow the SMBus address to which the device responds to be configured. In the master interface, these
address pins allow the SMBus address of the serial configuration EEPROM from which data is loaded to be configured. The SMBus address is set up
on negation of PERSTN by sampling the corresponding address pins. When the pins are sampled, the resulting address is assigned as shown in
Table 1.

Utilizing standard PCI Express interconnect, the PES6T5 provides the most efficient I/O connectivity solution for applications requiring high
The PES6T5 is based on a flexible and efficient layered architecture. The PCI Express layer consists of SerDes, Physical, Data Link and Transac-
The PES6T5 contains two SMBus interfaces. The slave interface provides full access to the configuration registers in the PES6T5, allowing every
Six pins make up each of the two SMBus interfaces. These pins consist of an SMBus clock pin, an SMBus data pin, and 4 SMBus address pins. In
