• Oscillators: SG-51PH 60.0000MC Application Field and Working Principle

Oscillators are among the most important components in the world of electronics. The SG-51PH 60.0000MC Oscillator is one such crucial oscillator used in advanced projects. It has a typical performance of -150 dBc/Hz phase noise with 1.0 V/?sec linear tuning at 2.7- 3.3 V supply, typically 0.8 pF load and 11.6 mA current consumption. With a frequency range between 59.0000 to 61.0000 MHz, this oscillator is an ideal solution for communications, aerospace and defense applications.

The SG-51PH 60.0000MC has a phase-locked loop (PLL) internal circuit based on quartz crystal technology with proper logic enabling tuning over the frequency band. It requires CMOS or TTL logic inputs with just a few components to make it up and running. Designers can adjust the frequency to a desired level by changing the input logic and voltage levels using a programming voltage circuit.

The advantage of an SG-51PH 60.0000MC over other oscillators is the frequency stability over the entire frequency band. The oscillator ensures excellent phase noise and jitter performance, with quality second-order Harmonic suppression up to -60 dB over a wide frequency range. Moreover, its wide tuning range of 1.4 to 8.3 GHz makes it suitable for a variety of applications requiring high-performance frequency stability from radio-frequency to cell phone technologies.

The SG-51PH 60.0000MC is also designed to last longer, with a fast response time of 15 us on average and a settling time of up to 60 us. It provides a phase-lock loop (PLL) outputs of up to 45 MHz with a low additive jitter of 2 ps RMS. The SG-51PH 60.0000MC oscillator is also capable of operating at temperatures between -40 to +125 ⁰C, guaranteeing reliability and precise operation under extreme atmospheric conditions.

The design of the SG-51PH 60.0000MC oscillator is based on the Pierce oscillator, which is a widely used architecture for voltage-controlled oscillators. It consists of two amplifiers, a voltage-controlled amplifier and a series-tuned amplifier. The output of the series-tuned amplifier is fed back to the voltage-controlled amplifier, thus providing the necessary gain to ensure oscillation over a wide frequency range. The frequency of oscillation is determined by the voltage applied to the voltage-controlled amplifier and two additional capacitances that envelope the entire circuit.

The SG-51PH 60.0000MC oscillator is used in a wide range of applications, such as radio transceivers for wireless communications, cellular phones, GPS devices, satellite modems and other wireless devices that require fast response time and robust performance over a wide temperature range. Its small size, relatively low power consumption, and unique characteristics make it an ideal solution for many applications.
