Working Principle

The SI5338C-B01271-GMR features a high-precision, temperature-compensated oscillator designed to provide clock signals with low-jitter and low-noise performance. The device encompasses an integrated crystal oscillator with a wide range of adjustable frequencies from 100MHz to 1.8GHz. It also has an integrated phase-locked loop (PLL) for clock multiplication of the input frequency and the capability to generate up to eight independent clock output signals. The use of a dedicated serial port enables the device to be programmed with a single pin or via multiple pins, providing increased design flexibility.

The device also incorporates a wide range of options including programmable duty cycle, symmetrical/asymmetrical duty cycle, and spread-spectrum clock outputs. All output signals are highly accurate and strictly controlled with very low duty cycle distortion and jitter. The outputs can be programmed to the desired frequency with ±50 ppm accuracy and up to 7.5 ps jitter. Additionally, the device\'s integrated power-on reset allows the device to reinitialize to the factory settings when power is cycled either on- or off.

The SI5338C-B01271-GMR is suitable for space-constrained applications such as communication, consumer, and industrial systems. It is available in a tiny, 8-pin small-outline package and operates over the industrial temperature range of -40°C to +105°C. It also incorporates a high-impedance output stage, allowing up to 68 Ω output impedance and a 50% duty cycle, making it suitable for driving very low-impedance loads. It is also protected against high ESD voltages, making it highly reliable and ideal for long-term use.
