IP4X-PCIE4XE31

Internal four PCIe x1 to PCIe x4 Gen 2 Switch Host Card

Introduction

IP4X-PCIE4XE31 is Internal four PCIe x1 to PCIe x4 Gen 2 Switch Host Card.

Utilizing the standard PCI Express Switch, the 8-Lane/5-Port PCI Express Gen 2 (5 GT/s) Switch provides the most efficient fan-out solution for the following configuration:

Technical Specifications

 

Upstream PCIe interface
  • 4-lane PCI Express
    • PCIe Gen 1 (2.5GT/s)
    • PCIe Gen 2 (5.0GT/s)
Downstream PCIe interface
  • Two IOI Proprietary Dual-lane Internal PCIe Ports (PCIe-1~2)
    • 10X2_19pin Header (Pitch=2.0mm)
    • 2-lane PCIe (Two PCIe x1)
  • Each Dual-lane Internal PCIe Port
    • PCIe Gen 1 (2.5GT/s)
    • PCIe Gen 2 (5.0GT/s)
Key Features
  • Standards compliant
    • Compliant with PCI Express Base Specification Revision 2.1
    • Compliant with PCI Express CEM Specification Revision 2.0
    • Compliant with PCI-toPCI Bridge Architecture Specification Revision 1.2
    • Compliant with Advanced Configuration Power Interface (ACPI) Specification
    • PCI Power Management Spec r1.2
  • PCI Express Power Management
    • Link power management states: L0, L0s, L1, L2/L3 Ready, and L3
    • Device states: D0 and D3hot
    • Active state power management for L0s and L1 states
  • Port Arbitration Round Robin (RR) and Weighted RR and Time-based Weighted RR
  • Extended Virtual Channel capability
    • Two Virtual Channels (VC) and Eight Traffic Class (TC) support
    • Disabled VCs’ buffer is assigned to enabled VCs for resource sharing
    • Independent TC/VC mapping for each port
    • Provides VC arbitration selection: Strict Priority, Round Robin (RR) and Programmable Weighted Round-Robin
  • Supports Isochronous Traffic
    • Isochronous traffic class mapped to VC1 only
    • Strict time based credit policing
  • Supports “Cut-through”(Default) as well as “Store and Forward” mode for switching packets
  • Peer-to-peer switching between any two downstream ports
  • Supports up to 512-byte maximum payload size (setting to 256-byte)
  • Enhanced Features
    • 150ns typical latency for packet running through switch without blocking
    • Supports Access Control Service (ACS) for peer-to-peer traffic
    • Supports Address Translation (AT) packet for SR-IOV application
    • Supports OBFF and LTR
Switch

  • Payload Size Supports up to 512-byte maximum payload size (Default is 256-byte)
  • Swing Level 700mV: In full swing signaling mode, the transmitters implement de-emphasis. 400mV: In half swing signaling mode, the transmitters not implement de-emphasis.
  • Virtual Channel 1 Disable: The unused VC1 queues (buffer) can be reassigned to VC0 and enable each of the ingress ports to handle more data traffic bursts. This virtual channel resource relocation feature enhances the performance of the PCIe Switch further. Enable: Isochronous traffic class mapped to VC1 only
Computer Platform Requirements Desktop computer equipped with a PCIe 2.0/3.0 x4, x8, x16 slot
Computer Platform
  • Computer with PCI Express slot (x4, x8, x16)

Note:
For the best performance (5.0 GT/s), It should be installed in a PCIe Gen 2 compliant slot in the host computer.  Most computers have PCIe Gen 2 (5.0 GT/s) throughput on x4, x8 or x16 slots.
A PCIe Gen 1 compliant slot reaches up to 2.5 GT/s throughput
