The PEX 8111 enables designers to quickly and easily upgrade existing PCI-based cards to the new AdvancedMC PCI Express interface. Whether the legacy product is a standard PCI add-on card, PCI Mezzanine card, or some other form factor, the addition of the PEX 8111 requires only 1 square centimeter of additional board real estate to convert the PCI interface to the new serial PCI Express. In addition, the bridge typically only draws about 400 milliwatts of additional power.
