1. Performance and utilization data are generated using an LFE3-70EA-8FN672CES device with Lattice Diamond 1.2 and Synplify Pro E-
2010.09L-SP2 software. Performance may vary when using a different software version or targeting a different device density or speed
gradewithin the LatticeECP3 family.
2. fMAX shown is for x4 operation at 3.125Gbaud using -8 speed grade devices.
Ordering Part Number
The Ordering Part Number (OPN) for the SRIO IP core targeting LatticeECP3 devices is SRIO-E3-U1.
Configuration and Licensing
IPexpress is the Lattice IP configuration utility, and is included as a standard feature of the Diamond and ispLEVER
design tools. Details regarding the usage of IPexpress can be found in the IPexpress and Diamond or ispLEVER
help system. For more information on the Diamond or ispLEVER design tools, visit the Lattice web site at:
