Universal Serial Bus - Related Standards

Related Standards

The PictBridge standard allows for interconnecting consumer imaging devices. It typically uses USB for its underlying communication layer.

The USB Implementers Forum is working on a wireless networking standard based on the USB protocol. Wireless USB is intended as a cable-replacement technology, and will use ultra-wideband wireless technology for data rates of up to 480 Mbit/s.

USB 2.0 High Speed Inter Chip (HSIC) is a chip-to-chip variant of USB 2.0 that eliminates the conventional analog transceivers found in normal USB. It was adopted as a standard by the USB Implementers Forum in 2007. The HSIC physical layer uses about 50% less power and 75% less board area compared to traditional USB 2.0. HSIC uses two signals at 1.2 V and has a throughput of 480 Mbit/s using 240 MHz DDR signaling. Maximum PCB trace length for HSIC is 10 cm. It does not have low enough latency to support RAM memory sharing between two chips.

Famous quotes containing the words related and/or standards:

    The content of a thought depends on its external relations; on the way that the thought is related to the world, not on the way that it is related to other thoughts.
    Jerry Alan Fodor (b. 1935)

    The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
