A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation. The output clock signal can range from a simple symmetrical square wave to more complex arrangements. The basic parts that all clock generators share are a resonant circuit and an amplifier.
Clock signal and legend. In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) [1] is an electronic logic signal (voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits.
A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards .
English: Clocking diagram (with appropriate colors) for the IEC 60309-2 low-voltage (<50V) connector. The clock hour refers to the position of the protective earth/ground pin, with the connector key referencing 6h.
In this image, the lower signal is the clock and the upper signal is the data. Data is recognized by the circuit at the positive edge of the clock. There are two time intervals illustrated in this image. One is the setup time, and the other is the timing margin. The setup time is illustrated in red in this image; the timing margin is ...

In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data is stored in memory devices called flip-flops or latches. The output of a flip-flop is constant until a pulse is applied to its "clock" input ...
One drawback of using source-synchronous clocking is the creation of a separate clock-domain at the receiving device, namely the clock-domain of the strobe generated by the transmitting device. This strobe clock-domain is often not synchronous to the core clock domain of the receiving device. For proper operation of the received data with other ...
