Programmable oscillators are electronic oscillator circuits whose frequency of operation can be easily reprogrammed by varying a control voltage or current. The SG-9101CE-D05SHCBA is one of such oscillators and it is commonly used in applications such as frequency-hopping radios, automatic frequency correction and frequency synthesizers.

The SG-9101CE-D05SHCBA is an integrated circuit that operates as an oscillator with adjustable frequency and adjustable gain. It consists of a voltage-controlled oscillator (VCO), a frequency divider, and a phase-frequency detector.

The voltage-controlled oscillator is a component in the SG-9101CE-D05SHCBA that can be programmed to generate a particular output frequency. The frequency is determined by the applied voltage, which can be adjusted by applying a control voltage to the VCO. The VCO has a wide operating range, allowing it to generate frequencies from a few kHz to several hundred MHz.

The other component in this oscillator is the frequency divider. It divides the output frequency from the VCO by a specific factor, to generate a lower frequency signal. This signal is then used as the reference input to the phase-frequency detector.

The phase-frequency detector is the component that compares two input frequencies and produces an error signal, which is used to adjust the VCO frequency. This error signal is generated by comparing the reference frequency from the frequency divider with the output frequency of the VCO. If the two frequencies are not the same, the phase-frequency detector will generate an error signal that is proportional to the difference in frequency. This signal is then sent to the VCO, which then adjusts its frequency so that it matches the reference frequency.

The SG-9101CE-D05SHCBA programmable oscillator is a useful component for many applications due to its wide range of frequency adjustment, low power consumption and ease of programming. It is commonly used for applications such as frequency-hopping radios, automatic frequency correction and frequency synthesizers.
