Serial Clock

A Serial Clock (SCK) is a timing signal used in synchronous serial communication protocols to coordinate data transmission between devices. It provides the rhythm that tells both the sender and receiver when to read or write each bit of data on the communication line. The SCK signal is typically generated by the master device in protocols like SPI (Serial Peripheral Interface) and ensures that data is sampled at the correct moments, preventing communication errors. Each pulse or edge of the clock signal corresponds to one bit of data being transferred.
