M-PCIe – Mobile PCI Express: PCI Express is going mobile!

What is Mobile PCI Express, M-PCIe

What is the  essential ingredient to M-PCIe? The answer is  MIPI’s new physical layer or. M-PHY. M-PCIe will replace the PCIe PHY layer with M-PHY and keep  the rest of the PCIe protocol stack unchanged including: data link layer, transaction layer, software layers and so forth.

M-PHY specification provides a serial interface technology with high bandwidth capabilities, which is particularly developed for mobile applications to obtain low pin count combined with very good power efficiency.

Mobile devices  require wider bandwidth, lower-pin count (serial) and higher power-efficient (network) interfaces. For PCI Express going mobile, replacing the current PCI Express PHY layer with MIPI's M-PHY was an excellent choice.
