Glossary

Term Description
DCE Data Communication Equipment. A communication device that controls the communication link. In serial communication, the DCE device is generally a modem or other serial device. See also DTE.
DCP Acronym for Dedicated Charging Port. Refers to a USB port defined in the Battery Charging Specification (BC v1.2) that is used strictly for power, requires no host connection and provides no data transfer capabilities.
DDI Acronym for Digital Display Interface. Depending on electrical interface and pin out, DDI can refer to DisplayPort, DVI, HDMI, SDVO or other digital video interfaces.
Derate A decrease in the rating of device characteristics, depending on operating conditions.
Differential Manchester Encoding A method of encoding serial data where a 1 is represented by a transition at the center of the bit cell with the opposite polarity from the transition at the center of the preceding bit cell. A 0 is represented by a transition at the center of the bit cell with the same polarity as the transition at the center of the preceding bit cell. In both cases, transitions at the beginning of the bit cell set up the level required to make the correct center transition. Also referred to as conditioned diphase or differential bi-phase encoding.
Digital A system that uses discrete states to represent information.
Digital Ground A common 0V ground reference for all digital signals. Digital ground and analog ground systems are usually wired separately to avoid introducing digital noise into the analog circuit.
Diode An electronic component that lets current flow only in one direction.
DisplayPort A VESA standard digital video interface that can transmit video, audio, USB and other forms of data.
Driver 1. A driver circuit, or buffer, that operates high-current or high-voltage devices. 2. Driver software links application programs and specific I/O devices.
