Device Overview
The 89HPES22H16 is a member of the IDT PRECISE family of
PCI Express switching solutions. The PES22H16 is a 22-lane, 16-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
fifteen downstream ports and supports switching between downstream
ports.
Features
◆
High Performance PCI Express Switch
– Sixteen maximum switch ports
Two x4 ports
Fourteen x1 ports
– Twenty-two 2.5 Gbps embedded SerDes
Supports pre-emphasis and receive equalization on per-port
basis
– Delivers 88 Gbps (11 GBps) of aggregate switching capacity
– Low-latency cut-through switch architecture
– Support for Max Payload Size up to 2048 bytes
– Supports two virtual channels and eight traffic classes
– PCI Express Base Specification Revision 1.1 compliant
◆
Flexible Architecture with Numerous Configuration Options
– Port arbitration schemes utilizing round robin algorithms
– Automatic per port link width negotiation from x4 to x2 or x1
– Automatic 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
◆
Highly Integrated Solution
– Requires no external components
– Incorporates on-chip internal memory for packet buffering and
queueing
– Integrates twenty-two 2.5 Gbps embedded full duplex SerDes,
8B/10B encoder/decoder (no separate transceivers needed)
◆
Reliability, Availability, and Serviceability (RAS) Features
– Redundant upstream port failover capability
– Supports optional PCI Express end-to-end CRC checking
