Working Principle

SIT1602BI-11-28N-48.000000E is composed of two building blocks: the oscillator core and the voltage-controlled frequency synthesizer (VCF). The oscillator core generates the main oscillation signal, which could be frequency modulated, providing a low phase noise output. The VCF tunes the output frequency of the oscillator core by means of a voltage input, and the synthesizer provides the fine tuning of the frequency. The circuit can be divided into two stages: a digital section and an analog one. The digital section of the circuit is controlled by a control voltage, which is an analog voltage applied externally. The analog section is composed of a wide baseband amplifier, a VCO, a low-noise amplifier, a voltage-controlled oscillator (VCO), and an output buffer.

SIT1602BI-11-28N-48.000000E is a low-noise, low-power, voltage-controlled oscillator designed to meet the needs of the various system applications. It offers outstanding performance, excellent value, and wide frequency range. The oscillator core and the VCF work together, providing an overall solution with low phase noise and wide tuning range.
