Adopted Flit-based (Flow Control Unit) encoding to manage the increased error rates inherent in PAM4. Key Architectural Shifts Instead of two voltage levels, PAM4 uses four

CXL 3.0 is physically layered on top of PCIe 6.0. This means that while you might never plug a "PCIe 6.0 GPU" into a slot, your server's memory expansion units will use the PCIe 6.0 PHY to run CXL protocols. This means that while you might never plug a "PCIe 6

If you need the actual PDF for legal compliance, design, or research:

The initialization sequence for PCIe 6.0 is unique. FLIT mode requires new training sequences (TS1/TS2 Ordered Sets). Developers need the PDF to code the "Link Training and Status State Machine" (LTSSM) correctly to negotiate down to 5.0 or 4.0 if the link is unstable.
