Ordering Part Number
The Ordering Part Number (OPN) for all configurations of the Turbo Encoder core targeting LatticeSC devices is
TURBO-ENCO-SC-U3. Table 4 lists the parameter settings that are available for the Turbo Encoder.
You can use the IPexpress software tool to help generate new configurations of this IP core. IPexpress is the Lattice
IP configuration utility, and is included as a standard feature of the ispLEVER design tools. Details regarding the
usage of IPexpress can be found in the IPexpress and ispLEVER help system. For more information on the
ispLEVER design tools, visit the Lattice web site at: www

1. Performance and utilization characteristics are generated using LFSC3GA25E-7F900C, with Lattice's ispLEVER 7.1 SP1
software. When using this IP core in a different density, speed, or grade within the LatticeSC family, performance and utili-
zation may vary.
