Linear pluggable optics driver and TIA
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 3
Linear driver and linear TIA pair for linear-drive pluggable optics, without retiming, relying on host SerDes equalisation.
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.
Interfaces
