The SI5350C-B03478-GT has various integrated features that allow for both cost and power savings. These features include an integrated low-dropout (LDO) regulator, which eliminates the need for an external PLL voltage regulator. Additionally, the on-board Phase-Frequency Detector (PFD) circuit provides the necessary stability properties, while the high speed clock outputs boast low jitter, making them ideal for sensitive applications.

The working principle of the SI5350C-B03478-GT is based on the fundamentals of phase locked loop (PLL) functionality. It receives an input clock signal and generates output clock signals of multiple frequencies based on the PLL control parameters. The device features a PFD, VCO, and loop filter components that are used to control the frequency of the output clocks.

The PFD generates a proportional voltage, based on the phase difference between the input and feedback clock signals, which is then used to control the VCO frequency. The loop filter then integrates this voltage to provide a DC level suitable for VCO control. The VCO operates by adjusting its frequency in response to the DC voltage level, thus helping to maintain the phase lock between the input and feedback signals. The loop filter also reduces the high frequency noise components resulting from VCO frequency change.

Additionally, the SI5350C-B03478-GT features an internal phase divider that divides the input frequency by a factor of 1/N, where N is an adjustable factor. This feature allows for simultaneous output of multiple frequencies from the device. The output frequency range is determined by the input frequency and the phase divider factor N.

The SI5350C-B03478-GT is a versatile, cost-effective, and highly accurate frequency synthesis and timing solution, designed for a wide range of applications such as DSP, microprocessor systems, and distributed sources. It utilizes efficient phase-locked loop technology and features multiple output frequencies with excellent phase noise, jitter, and stability characteristics.
