Current mode logic or CML is a differential digital logic family intended to transmit data at speeds between 312. Differential signaling is a method of transmitting Information electrically by means of two complementary Signals sent on two separate wires A digital system uses discrete (discontinuous values usually but not always Symbolized Numerically (hence called "digital" to represent information for In Computer engineering, a logic family may refer to one of two related concepts 5 Mbit/s and 3. In Telecommunications and Computing, bitrate (sometimes written bit rate, data rate or as a Variable R or f b 125 Gbit/s over a standard printed circuit boards. A printed circuit board, or PCB, is used to mechanically support and electrically connect Electronic components using conductive pathways or traces [1]
The transmission is point-to-point, unidirectional and is usually terminated at the destination with 50 Ω resistors to Vcc on both links. Electrical termination of a signal involves providing a terminator at the end of a wire or cable to prevent an RF signal from being reflected The ohm (symbol Ω) is the SI unit of Electrical impedance or in the Direct current case Electrical resistance, |- align = "center"| |width = "25"| | |- align = "center"| || Potentiometer |- align = "center"| | | |- align = "center"| Resistor| | Almost all Integrated circuits (ICs have at least two pins which connect to the power rails of the circuit they are installed in CML logic is the physical layer used in DVI and HDMI video links, and is frequently used in interfaces to fiber optic components.
