LPDDR5/LPDDR5X PHY
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 2
LPDDR5 and LPDDR5X PHY with WCK clock tree, duty-cycle monitor, read DQ calibration and DFI 5.0 interface.
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.
