Working Principles

The SI5338B-B06415-GM operates by first taking an input clock and running it through an adjustable frequency MultiSynth circuit. This circuit adjusts and tunes the frequency of the incoming clock signal, allowing it to be converted into one of the 8 output frequencies. The 8 customizable output frequencies can then be used to vary the speed of various peripherals such as motors, sensors, and other timing sensitive devices. To ensure a consistent and reliable output clock source, the SI5338B-B06415-GM is equipped with a versatile jitter-attenuation feature. The jitter-attenuation feature allows for a customizable jitter-attenuation curve to be programmed into the device. This allows for a smooth frequency transition and stability of the output clock.

To further customize the behavior of the SI5338B-B06415-GM, it can be programmed to provide a selectable output for each individual clock output. These selectable outputs are composed of a mix of one of four predefined waveforms. These waveforms provide control of the dynamic input and output levels, rise/fall-time, and duty cycle in order to ensure the output that is compatible with the end users device requirements. The SI5338B-B06415-GM also offers an optional low-power standby mode.
