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.
The master clock in a clock network can receive accurate time in a number of ways: through the United States GPS satellite constellation, a Network Time Protocol server, the CDMA cellular phone network, a modem connection to a time source, or by listening to radio transmissions from WWV or WWVH, or a special signal from an upstream broadcast network.
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.
Channel-Link uses LVDS, and comes in configurations with three, four, or eight parallel data transfer lanes plus the source-synchronized clock for each configuration. In cable applications, it uses one twisted pair in order to transmit a clock signal, and on the remaining differential pairs it transmits digital data at a bit rate that is seven ...
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 ...
Various applications require clocks with predefined signal and performance specifications. Of these, the key specifications are phase noise and frequency stability. Phase noise has been optimized by raising the resonator's natural frequencies (f) and quality factors (Q).
The device which generates the word clock is the clock source for all the other audio devices. The signal is used for synchronizing digital audio signals between devices, such as CD players, audio I/O cards, etc. [1] It allows all the components in the signal path to process the data and remain synchronized with each other. [2]
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 ...
