Description
Peripheral Component Interface Express – next-generation high speed Serialized I/O bus
One PCI Express Lane is a set of 4 signals that contains two differential lines for
Transmitter and two differential lines for Receiver. Clocking information is embedded into the data stream.
x1 refers to one PCI Express Lane of basic bandwidth; x2 to a collection of two PCI Express Lanes; etc.. Also referred to as x1, x2, x4 or x16 link.
PCI Express Mini Card add-in card is a small size unique form factor optimized for mobile computing platforms.
MMCplus was defined for first time in MMC System Specification v4.0. MMCplus is backward compatible with MMC. MMCplus has 13 pins.
SDIO (Secure Digital Input Output) is a non-volatile memory card format developed for use in portable devices.
Universal Serial Bus
Serial AT Attachment: serial-interface standard for hard disks
High Definition Audio
S/PDIF (Sony/Philips Digital Interconnect Format) specifies a Data Link Layer protocol and choice of Physical Layer specifications for carrying digital
audio signals between devices and stereo components.
High Definition Multimedia Interface. HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable.
Transition Minimized Differential Signaling. TMDS is a signaling interface defined by Silicon Image that is used for DVI and HDMI.
Digital Visual Interface is a video interface standard developed by the Digital Display Working Group (DDWG).
Low Pin-Count: a low speed interface used for peripheral circuits such as Super I/O controllers, which typically combine legacy device support into a
single IC.
Inter-Integrated Circuit Bus: is a simple two-wire bus with a software-defined protocol that was developed to provide the communications link
between integrated circuits in a system.
System Management Bus: is a popular derivative of the I²C-bus.
Controller Area Network
Serial Peripheral Interface
