Working Principle

The S-1411H47-A8T1U4 uses an ultra-low power oscillator to produce a high frequency or low frequency clock signal. This device is capable of producing precision frequency sweep slopes with a minimum of side bands and low jitter. The oscillator itself consists of a quartz resonator, a temperature compensation circuit, and a programmable control logic circuit. The oscillator can be configured for a wide range of frequencies with a minimum number of components. Using the integrated voltage reading circuit, the oscillator maintains a constant frequency within a given temperature range.

The S-1411H47-A8T1U4 also includes a frequency synthesizer to produce an accurate frequency reference. The frequency synthesizer is a closed-loop system that includes an Internal reference oscillator (IRO) providing frequency accuracy and stability. The frequency synthesizer adjusts its output frequency to match the IRO frequency. The synthesizer also includes a phase-locked loop (PLL) circuit to help maintain the frequency accuracy of the reference frequency and the output of the timer when subjected to external perturbations. This increases the system\'s accuracy and reliability.
