• Mobile handsets and wireless data cards
• Base stations
• Computing applications such as laptops and desktops
• Industrial and automotive applications, such as industrial automation, navigation, infotainment, and powertrain control

The SI5335A-B04098-GM also features an integrated temperature sensor, as well as a programmable temperature characterization register. These features allow for system-level temperature compensation and enhance the stability of the clock under varying environmental conditions. This makes it especially suitable for automotive, medical and industrial applications.

Working Principle

The SI5335A-B04098-GM uses four main components to generate high-quality, low-power clocks: a phase-locked loop (PLL), a digital frequency synthesizer, an integrated temperature sensor and an oscillator. This combination of components allows it to generate high-frequency, low-jitter clocks.

The PLL is the main processor within the SI5335A-B04098-GM that is responsible for controlling the output frequency. It is programmed to generate a set of digital control signals corresponding to the wanted clock signals. These signals are then sent to the digital frequency synthesizer, which produces the actual clock signals.

The integrated temperature sensor sends out signals to the PLL when the temperature changes. This enables the PLL to adjust the clock outputs, allowing for system-level temperature compensation and producing more stable clock signals under different environmental conditions.

Finally, the oscillator is responsible for generating a low-noise, stable clock signal. The oscillator also has a temperature-compensation circuit, ensuring even more accurate clock signals.

In conclusion, the SI5335A-B04098-GM is a low-power, low-jitter clock generator with many applications in today\'s telecom, computing, industrial and automotive markets. It is suitable for a variety of applications due to its features such as low-power consumption and small form factor. Its combination of a PLL, digital frequency synthesizer, integrated temperature sensor and oscillator enables it to generate high-frequency, low-jitter clocks. This makes it an ideal solution for environment-sensitive applications, such as those used in automotive, medical and industrial applications.
