CPRI link controller
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 3
CPRI radio equipment controller and radio equipment link with line rates options 1 to 10, hyperframe framing, IQ mapping, control and management channels and delay measurement.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
