USB4 PHY
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 3
USB4 PHY for Gen 2/Gen 3 NRZ and Gen 4 PAM3 (80 Gb/s) with asymmetric lane modes, also supporting USB 3.2 and DisplayPort alternate mode.
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.
