It has a very low jitter and is capable of generating very high frequency outputs, making it ideal for applications requiring ultra-high performance clocking. The SI5340A-A-GMR generates its output clocks by using the fundamental principle of phase locked loops (PLL). A phase-locked loop (PLL) is a circuit block that consists of a voltage-controlled oscillator (VCO), a phase comparator and a frequency divider. The PLL is used to synchronize a signal from the “reference clock” to the “feedback clock”. The reference clock is the input clock and is used as the reference for the oscillator. The feedback clock is the output of the VCO and is used to compare the phase of itself to the reference clock. Once the phases are matched, the PLL will attempt to maintain that phase relationship. The SI5340A-A-GMR also has an integrated Spread Spectrum feature which helps reduce EMI emissions while maintaining the high-frequency output clock accuracy. This enables the device to be used in applications where EMI is a concern. The SI5340A-A-GMR provides a low jitter on both input and output clocks, making it ideal for applications that require tight timing performance.
