Network and communication chips are semiconductor integrated circuits (IC) used in telecommunication devices and systems. Network and communication chips 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). Network and communication chips can also use Ethernet, Fibre Channel, IEEE 1394 or FireWire^® (Apple Computer), Microwire^® (National Instruments), PanelBus, high-speed downlink packet access (HSDPA), inter-integrated circuit (I2)C, infrared data access (IrDA), global positioning system (GPS), general packet radio service (GPRS), low-voltage CMOS (LVCMOS), subscriber identification modules (SIM), small computer systems interface (SCSI), and the VersaModule Eurocard bus (VMEbus). Network and communication chips that use peripheral component interconnect (PCI), compact PCI (cPCI), and PCI Express (PCIe) are also available.
