Figure 2-5: PCIe x16 Expansion Slot

2.4.3.2 PCIe x16 Bus Specifications

The PCIe port is compliant with the PCI Express* Base Specification revision 1.1. The
PCIe x16 port operates at a frequency of 2.5 Gb/s on each lane while employing 8b/10b
encoding; the port supports a maximum theoretical bandwidth of 40 Gb/s in each
direction. Some of the features are listed below.

 One, 16-lane PCIe port intended for graphics attach, compatible to the PCI

Express* Base Specification revision 1.1a.

 PCI Express frequency of 1.25 GHz resulting in 2.5 Gb/s each direction
 Raw bit-rate on the data pins of 2.5 Gb/s results in a real bandwidth per pair of

250 MB/s given the 8b/10b encoding used to transmit data across this
interface

 Maximum theoretical realized bandwidth on the interface of 4 GB/s in each

18 ©Copyright 2009 CyberResearch, Inc.

direction simultaneously, for an aggregate of 8 GB/s when x16.

 PCI Express* Graphics Extended Configuration Space. The first 256 bytes of

configuration space alias directly to the PCI Compatibility configuration space.
The remaining portion of the fixed 4-KB block of memory-mapped space
above that (starting at 100h) is known as extended configuration space.

 PCI Express Enhanced Addressing Mechanism. Accessing the device

configuration pace in a flat memory mapped fashion.

 Automatic discovery, negotiation, and training of link out of reset
 Supports traditional PCI style traffic (asynchronous snooped, PCI ordering)
 Supports traditional AGP style traffic (asynchronous non-snooped, PCI

Express relaxed ordering)

 Hierarchical PCI-compliant configuration mechanism for downstream devices

(i.e., normal PCI 2.3 Configuration space as a PCI-to-PCI bridge)

 Supports “static” lane numbering reversal. This method of lane reversal is

controlled by a Hardware Reset strap, and reverses both the receivers and
transmitters for all lanes (e.g., TX[15]->TX[0], RX[15]->RX[0]). This method is
transparent to all external devices and is different than lane reversal as
defined in the PCI Express Specification. In particular, link initialization is not
affected by static lane reversal.

3.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the MXGD
may result in permanent damage to the MXGD and severe injury to the
user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the MXGD. Dry climates are especially susceptible to ESD. It is therefore critical
that whenever the MXGD, or any other electrical component is handled, the following
anti-static precautions are strictly adhered to.

 Wear an anti-static wristband: - Wearing a simple anti-static wristband can

help to prevent ESD from damaging the board.

 Self-grounding:- Before handling the board touch any grounded conducting

material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.

 Use an anti-static pad: When configuring the MXGD, place it on an

antic-static pad. This reduces the possibility of ESD damaging the MXGD.

 Only handle the edges of the PCB:-: When handling the PCB, hold the PCB

by the edges.

3.2 Unpacking

3.2.1 Unpacking Precautions

When the MXGD is unpacked, please do the following:

 Follow the anti-static precautions outlined in Section 3.1.
 Make sure the packing box is facing upwards so the MXGD does not fall out

of the box.

 Make sure all the components shown in Section 3.3 are present.

5.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the MXGD
may result in permanent damage to the MXGD and severe injury to the
user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the MXGD. Dry climates are especially susceptible to ESD. It is therefore critical
that whenever the MXGD, or any other electrical component is handled, the following
anti-static precautions are strictly adhered to.

 Wear an anti-static wristband: - Wearing a simple anti-static wristband can

help to prevent ESD from damaging the board.

 Self-grounding:- Before handling the board touch any grounded conducting

material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.

 Use an anti-static pad: When configuring the MXGD, place it on an

antic-static pad. This reduces the possibility of ESD damaging the MXGD.

 Only handle the edges of the PCB:-: When handling the PCB, hold the PCB

by the edges.
