Pci Express M.2 Specification Revision 5.0 Version 1.0 Pdf «FHD»
: Implemented electrical changes to reduce noise and improve signal quality at the higher 32 GT/s frequency.
Note: The M.2 specification is separate from the PCIe Base Specification, but it depends on it. Rev 5.0 of M.2 references PCIe Base 5.0 for link layer and transaction layer details. pci express m.2 specification revision 5.0 version 1.0 pdf
While the specification maintains the physical footprint that has become ubiquitous in modern computing, the underlying electrical architecture has been fundamentally overhauled to support raw data transfer rates of 32 GT/s (gigatransfers per second) per lane, effectively doubling the bandwidth of the previous generation. : Implemented electrical changes to reduce noise and
At 32 GT/s, signal loss over the short M.2 trace (approx. 3 to 8 inches) becomes dramatic. The new spec mandates stricter and crosstalk limits . For the first time, Rev 5.0 introduces mandatory requirements for SMT (Surface Mount Technology) capacitors on the module's high-speed lanes to combat resonance. The new spec mandates stricter and crosstalk limits
