Integrated circuit (IC) interfaces are semiconductor chips that are used to control and manage the sharing of information between devices. IC interfaces use many different technologies. Choices include current mode logic (CML), gunning transceiver logic (GTL), and gunning transceiver logic plus (GTLP); emitter coupling logic (ECL), positive ECL (PECL), and low-voltage PECL (LVPEC); low-voltage differential signaling (LVDS), bus LVDS (BLVDS), and multi-point LVDS (M-LVDS); digital visual interface (DVI) and high-definition media interface (HDMI); and digital subscriber line (DSL) and integrated services digital network (ISDN). IC interfaces can also use technologies such as actuator-sensor interface (AS-i), Ethernet, Fibre Channel, IEEE 1394 or FireWire® (Apple Computer); Microwire or PanelBus; high-speed downlink packet access (HSDPA), inter-integrated circuit (I2C), infrared data access (IrDA), global positioning system (GPS), general packet radio service (GPRS), low-voltage CMOS (LVCMOS), synchronous optical network (SONET), subscriber identification modules (SIM), small computer systems interface (SCSI), and the VersaModule Eurocard bus (VMEbus). Peripheral component interconnect (PCI), compact PCI (cPCI), and PCI Express (PCIe) IC interfaces are also available.
