PCI Express Solutions

PCI Express (Peripheral Component Interconnect Express) is a high performance, scalable, well defined standard for a wide variety of computing and communications platforms.  It has been defined to provide software compatibility with existing PCI drivers and operating systems.  Lattice provides customers with low-cost and low-power programmable solutions that are ready-to-use right out of the box.  For PCI Express a full suite of tested and interoperable solutions is available that includes:

Lattice tests all critical components of the PCI Express stack rigorously, and puts a great deal of emphasis on interoperability with proven 3rd party silicon platforms. The following test documentation is available for customer review.

PMA Electrical Characterization

• TN1084 and Supplements (available under NDA) for PCI Express Transmit Jitter Specifications.
• We also perform additional testing for performance over PCI Express Cable using a Molex 28AWG Cable Assembly.

PCI SIG Testing

Lattice is a regular participant of the PCI SIG and its Compliance Workshop programs. Testing is done on Lattice designed PCI Express End Point Add-in cards. All PCI Express End Point solutions have undergone rigorous testing and are currently compliant to Version 1.1 of the PCI Express specification. The following test are performed at the SIG:

• Electrical Testing – Examines device and card signal quality for eye pattern, jitter and bit error rate.
• Configuration Space Testing – Examines configuration space in the device by verification of required fields and values
• Link and Transaction Protocol Testing – Tests device behavior for link-level and transaction layer protocols.

Interoperability

Lattice PCI Express solution undergo peer to peer compatibility tests with various motherboards and processors. These tests are held internally as well as at the PCI SIG Compliance Workshops. The Lattice PCI Express solutions have successfully completed interoperability with over 20 motherboards with a variety of processors.
