Working Principle

SI5338B-B07258-GM is an oscillator component, which output various frequency outputs and require a specialized source of power. In order to work, the component requires a dc power supply with voltage between 1.62 V and 3.63 V and support a wide range of frequencies from 1 Hz to 250 MHz. It also supports a wide range of factory and user programmable output frequencies with low jitter and high resolution. This component is also highly configurable, with adjustable output drive, digital programming and configuration from the host, auto arming control and programmable LVDS buffer output.

Apart from power inputs and configuration, the component requires a signal input in order to oscillate and start the output. This can be provided by an external signal source such as a reference clock or a logic signal. The signal is usually a 0V to 3.3V logic signal that is applied externally to the oscillator input pin. The oscillator will start to oscillate once a signal is detected, and the output frequency is set according to the signal configuration setting.

This component is designed to operate in highly configurable conditions in terms of frequency and jitter attenuation. Apart from the signal input and configuration, the component has a jitter attenuator onboard which helps to reduce the jitter in the frequency output and improves the signal symmetry. The jitter attenuator consists of an analog phase-locked loop (PLL) to help reduce the jitter, it works by track the input signal and attenuate the jitter at lower frequencies.

SI5338B-B07258-GM is an oscillator component that has been well optimised for its application field. It’s wide range of output frequencies, low jitter and high resolution makes it suitable for different application areas such as consumer, communications, industrial and medical fields. It is also highly configurable and integrated, allowing users to easily program and configure their product according to their application needs. Finally, the on-board jitter attenuator helps reduce any jitter that may be present in the frequency output, making this component a great choice for high performance oscillators.
