PCIe 6.0 introduces (Pulse Amplitude Modulation with 4 levels). Instead of two voltage levels, PAM4 uses four levels to encode two bits per clock cycle (00, 01, 10, 11). The PCI Express Base Specification Revision 6
: PCIe 6.0 incorporates advanced signal integrity techniques to maintain signal quality over longer distances and at higher speeds. This ensures reliable data transmission, which is vital for mission-critical applications. Disclaimer: This article is for informational purposes
With the introduction of PAM-4 and FEC, the traditional way of breaking data into packets became inefficient. PCIe 6.0 introduces .
The PCIe specification has always prided itself on backward compatibility. A PCIe 6.0 link will fall back to the highest common supported speed.
