Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 2
Low-power 112G PAM4 SerDes for extra-short and very-short reach links to optical engines, chiplets and pluggable modules, with reduced 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.
