Working Principle

The SI5338C-B01247-GM is designed to generate high-frequency, low-jitter clock signals. This is accomplished by incorporating a phase-locked loop (PLL) with two phase-frequency detectors and two programmable PLL control loops. The phase-frequency detectors detect the phase discrepancy between the input and output frequencies and then adjust the PLL voltage control oscillator (VCO) frequency to maintain the desired output frequency. This process results in reliable, low-jitter clock signals.

The SI5338C-B01247-GM also features synchronization inputs for systems operating at multiple frequencies. It is designed to generate multiple outputs that are synchronized to an input reference clock. The device is designed with a high-performance PLL, an integrated 6-tap jitter filter, and a wide range of PLL and clock output options including LVCMOS, LVDS, and HCSL outputs.

The SI5338C-B01247-GM is well suited for applications such as avionics, test and measurement, medical, and communications systems, where reliable and low-jitter clocks are required. It provides excellent phase noise performance, operating temperature range of -40 to +85°C, and a wide range of clocking options, making it an ideal solution for applications that need to minimize jitter and power consumption while providing a reliable output frequency.
