Specifically, it offers ultra-low phase noise performance and extremely low frequency variability over temperature, voltage, and aging. This makes it well-suited for applications such as frequency synthesizers, local oscillators, clock generators, timing circuits, and clock dividers.

Application Field

The application fields of SG7050CBN 125.000000M-TJGA3 are vast. This oscillator is suited for use in frequency synthesizers, clock sources and dividers, modems, set-top boxes, PCs, digital signal processing (DSP), timing circuits, phase-locked loops (PLLs), data converters, digital receivers, and more. It can also be used in high-speed digital synchronization applications where ultra-fast response time, low short-term jitter, and tight tolerance to frequency are important.

Working Principle

The SG7050CBN 125.000000M-TJGA3 works on the principle of a negative feedback oscillator. The negative feedback maintains the output frequency at the desired value. The basic components of this oscillator are an electronic switch, such as a transistor, and a capacitor. The switch is turned on and off at a certain frequency by the output of an amplifier. A capacitor also connects to the amplifier’s output. When the switch is on, the capacitor receives a charge. When the switch is off, the capacitor discharges, providing a negative feedback to the amplifier and maintaining the output at the desired frequency.

The SG7050CBN 125.000000M-TJGA3 has an additional start-up circuit to help start the oscillation process. This start-up circuit consists of a resistor and capacitor connected in series to the input of the inverter circuit. The resistor and capacitor are used to generate a stable DC voltage across the inverter’s input. Once the oscillation starts, the start-up circuit is bypassed. The feedback circuit is used to control the frequency. By varying the resistance in the feedback circuit, the frequency of the oscillator can be adjusted.

The SG7050CBN 125.000000M-TJGA3 is an advanced oscillator designed for highly accurate and stable timing and frequency applications. It is capable of producing high-frequency signals with low phase noise and short-term jitter. Its wide frequency range, low frequency variability over temperature, voltage, and aging, and its start-up circuit make it well-suited for a variety of applications.
