Working Principle of the SI5367B-C-GQ

The SI5367B-C-GQ works by using a phase-locked-loop (PLL) to generate the output frequency from a programmable voltage-controlled oscillator (VCO). The PLL locks the generated frequency to a reference frequency and generates precise clocking signals. These clock signals are then used to drive other digital circuits. The reference frequency is provided by an external clock or a crystal oscillator.

The output frequency of the SI5367B-C-GQ can be programmed with a variety of precision frequency settings. This is done by programming a set of integer and fractional registers with the desired output frequency. The frequency stability is achieved through an on-board, low-power temperature compensation circuit. This enables the device to maintain a precision frequency even when the ambient temperature changes.

The SI5367B-C-GQ also features an integrated jitter cleaner (IJC) to reduce phase noise and jitter in the output signal. This is done by using a special low-noise, low-phase-noise loop filter. Additionally, the device also features an integrated sigma-delta modulator for further jitter cleaning.

The SI5367B-C-GQ also features a wide range of other features such as spread spectrum clock modulation, dual independent outputs, advanced synchronization and trigger modes, and a built-in watch dog timer for fault monitoring. Additionally, the SI5367B-C-GQ also supports multiple control interfaces, such as I2C, SPI, and a two-wire UART.

Conclusion

The SI5367B-C-GQ is a highly flexible and reliable clock/timing device that offers precise frequency synthesis and jitter-free timing. Its advanced features make it ideal for a variety of applications, from communication systems and industrial automation systems to data centers and home automation systems. Its wide range of features, including integrated jitter cleaning, spread spectrum clock modulation, and multiple control interfaces, make the SI5367B-C-GQ one of the most advanced clock/timing devices available.
