Devic e Overview
The 89HPES3T3 is a member of IDT’s PRECISE famly of PCI
Express switching solutions. The PES3T3 is a 3-lane, 3-port peripheral
chip that performs PCI Express Base switching. It provides connectivity
and switching functions between a PCI Express upstreamport and up to
four downstreamports and supports switching between downstream
ports.
Features
High Performance PCI Express Switch
– Three 2.5Gbps PCI Express lanes
– Three switch ports
– x1 Upstreamport
– Two x1 Downstreamports
– Low latency cut-through switch architecture
– Support for Max payload sizes up to 256 bytes
– One virtual channel
– Eight traffic classes
– PCI Express Base Specification Revision 1.1 compliant
◆
Flexible Architecture with Numerous Configuration Options
– Automatic lane reversal on all ports
– Automatic polarity inversion on all lanes
– Ability to load device configuration fromserial EEPROM
◆
Legacy Support
– PCI compatible INTx emulation
– Bus locking
◆
Highly Integrated Solution
– Requires no external components
– Incorporates on-chip internal memory for packet buffering and
queueing
– Integrates three 2.5 Gbps embedded SerDes with 8B/10B
encoder/decoder (no separate transceivers needed)
◆
Reliability, Availability, and Serviceability (RAS) Features
– Internal end-to-end parity protection on all TLPs ensures data
integrity even in systems that do not implement end-to-end
CRC (ECRC)
– Supports ECRC and Advanced Error Reporting
– Supports PCI Express Native Hot-Plug, Hot-Swap capable I/O
– Compatible with Hot-Plug I/O expanders used on PC mother-
boards
◆
Power Management
– Utilizes advanced low-power design techniques to achieve low
typical power consumption
– Supports PCI Power Management Interface specification (PCI-
PM1.2)
– Unused SerDes are disabled.
– Supports Advanced Configuration and Power Interface Speci-
fication, Revision 2.0 (ACPI) supporting active link state
◆
Testability and Debug Features
– Built in Pseudo-RandomBit Stream(PRBS) generator
– Numerous SerDes test modes
– Ability to bypass link training and force any link into any mode
– Provides statistics and performance counters
