What is "SCL"?


"SCL" stands for "Serial Clock" and it is a signal used in digital communication protocols such as I2C (Inter-Integrated Circuit) and SMBus (System Management Bus).

In an electronic circuit, the SCL signal is used to synchronize the data transfer between two devices, typically a master device and a slave device. The SCL signal is generated by the master device and is used to indicate when the data on the SDA (Serial Data) line is valid and can be read or written by the slave device.

The SCL signal is typically a square wave with a frequency that is determined by the communication protocol being used. The frequency of the SCL signal determines the rate at which data is transmitted between the devices, and it is important to ensure that the SCL signal meets the timing requirements of the communication protocol being used.
