Working Principle

The 653L15556A2T works on the principle of voltage-controlled oscillation (VCO). VCO is an oscillatory circuit which oscillates at a frequency that is directly proportional to the applied voltage. When a signal of the required frequency and phase is applied to the control input, the oscillator starts to generate an output with a frequency which is a multiple of the original signal. The oscillation frequency can be adjusted by varying the control voltage.

To obtain the desired frequency and jitter performance, the integrated oscillator core uses a temperature-compensated crystal to adjust the frequency accuracy, and a digitally-controlled gain element to adjust the frequency range. The result is a highly accurate and reliable oscillator capable of operating over a wide frequency range.

Summary

The 653L15556A2T is a high-performance VCXO device that provides low-jitter and low-power operation. Its wide range of input voltage and integrated CMOS output makes it suitable for use in various communications, digital, and embedded systems applications. Its working principle is based on VCO with temperature-compensated crystal and digitally-controlled gain element for precise frequency and stability performance.
