SG-8003CE-PEL

Programmable oscillators refer to oscillators that can be adjusted and adjusted to meet the needs of different occasions. Specifically, the frequency, phase, duty cycle and other parameters can be changed within a certain range. SG-8003CE-PEL is an example of programmable oscillators.

SG-8003CE-PEL is an ultra-low-jitter clock generator with signal output frequency range from 0.05GHz to 2.5GHz, power supply from 2.5V to 3.3V, and up to 250MHz time domain jitter performance. It integrates a digitally controlled oscillator (DCO), loop filter and voltage controlled oscillator (VCO), making SG-8003CE-PEL programmable for output frequency.

In terms of its application fields, SG-8003CE-PEL integrates a frequency modulator and can adjust the output frequency from 0.1kHz to 2.5GHz. Its integrated switching DC/DC converter can provide 18mW to 500mW power, which makes it suitable for applications such as telecom base stations, wireless backbones, and industrial systems. In the military and aerospace field, SG-8003CE-PEL can provide an accurate timestamp signal and minimize the set up and hold times in the instrument platform.

This oscillator is derived from the principle of varying the control signal input level to adjust the output frequency. The working principle of the SG-8003CE-PEL programmable oscillator is based on the traditional voltage-controlled oscillator (VCO) circuit. Firstly, the DCO sends an output signal to the loop filter, which is tuned according to the power-on state, then the signal is sent to the VCO, and the signal of the voltage-controlled oscillator is amplified and sent back to the DCO. At this time, its output frequency should be the same as the frequency of the signal added to the VCO. After receiving the output signal, the loop filter takes charge of the signal processing of frequency adjustment, amplitude adjustment and harmonic distortion suppression.

Besides, SG-8003CE-PEL also has an ultra-low jitter frequency synthesizer, which can provide frequency switching time of less than 5 nanoseconds, the jitter frequency of up to 250MHz and the jitter amplitude of up to 0.5%. It has a power output range of 18mW to 500mW and a noise cancellation circuit that adjusts the stability of the output signal and eliminates the noise caused by being close to other circuits.

In summary, SG-8003CE-PEL is an example of programmable oscillators with its frequency range, power supply range, jitter performance and power output range, which makes it suitable for telecom, wireless base stations, industrial systems and military aerospace applications. The working principle of this oscillator is based on the VCO circuit to adjust the output frequency. The ultra-low jitter and noise cancellation circuit are beneficial for the stability of the oscillator and accurate frequency timing.
