Working Principle

The SI5338C-B04360-GM clock generator supports high-frequency operation with low-jitter, making it ideal for high-performance testing. It is based on a fractional-N PLL architecture and utilizes innovative methods such as dual loops, dual modulation, and an advanced jitter attenuator to cancel out jitter.

The clock generator consists of three main components; the VCO, loop filter, and frequency divider. The VCO is used to generate a reference clock signal that is divided down by the frequency divider. This signal is then input into the loop filter, which adjusts the phase and frequency. The loop filter is then used to provide the feedback signal to close the loop and provide a stable clock signal with low jitter.

The SI5338C-B04360-GM also features integrated programmable output power control, allowing a wide range of output power levels to be set depending on system requirements. Additionally, it is capable of accommodating a wide range of input input frequencies and synthesize a wide range of output frequencies.
