590FD50M0000DGR Oscillators

Oscillators are components used in a wide variety of electronic systems. They are responsible for providing the required signal frequency by creating a periodic signal, which is then used to produce a voltage or current. The 590FD50M0000DGR oscillator is one such device, designed for use in high-speed applications.

Application Field

The 590FD50M0000DGR oscillator is a device primarily used in high-frequency applications, such as in signal processing systems, clock synchronization, and radio frequency communications. The high frequency requirements of these systems are so critical that ordinary oscillators cannot be used. They require an oscillator with very low jitter and high frequency accuracy.

The 590FD50M0000DGR oscillator has a frequency range of 10MHz to 500MHz, and a low jitter of 1ps pp (peak to peak). This makes it suitable for use in a wide variety of applications, including frequency synthesis, frequency hopping radio systems, digital clock generators, phase-locked loops (PLLs), and pulse code modulation (PCM) telecommunications systems.

Working Principle

The 590FD50M0000DGR oscillator is based on the phase-locked loop (PLL) principle. The PLL circuit involves the continuous comparison of two signals: a reference signal and a feedback signal. The reference signal is generated external to the oscillator, while the feedback signal is generated inside the oscillator. By continuously comparing the two signals, the PLL circuit can keep the oscillator’s frequency in synchrony with the reference signal.

The reference signal is generated by an external source such as a voltage-controlled oscillator (VCO). The feedback signal is generated by a voltage-controlled oscillator (VCO) inside the oscillator. The VCO is a resonant device that will produce a periodic signal with a frequency that is determined by the voltage applied to its control terminals. The two oscillators are then compared using a phase comparator, which is able to detect even the slightest differences in frequency.

The output of the phase comparator is fed to a low-pass filter, which eliminates the high frequency components of the signal. The filtered signal is then fed to the VCO’s control terminals, adjusting its frequency so as to keep it in synchrony with the reference signal. This feedback loop forms the basic principle of operation of the 590FD50M0000DGR oscillator.

Additional Features

The 590FD50M0000DGR oscillator has a number of additional features that make it suitable for use in high-speed applications. Firstly, the oscillator is designed for use in a range of system temperatures. It is capable of operating from -40°C to +85°C with no degradation in performance.

The oscillator also has a low start-up time of 10ms or less, making it suitable for systems with tight timing requirements. Additionally, it is designed for frequency accuracy over a wide temperature range, and for excellent overall reliability. This makes it suitable for use in critical applications, such as in medical devices or other mission-critical systems.

Overall, the 590FD50M0000DGR oscillator is an excellent choice for high-speed applications that require precise frequency control and low jitter. Its low start-up time, wide temperature range, and high frequency accuracy make it suitable for a wide variety of critical applications.
