AX7DAF4-100.0000T

Oscillators are circuits that generate cyclical voltage waveforms, usually at frequencies far too high to be measured by a typical multimeter. Among oscillators, the AX7DAF4-100.0000T is an ultra-low jitter voltage-controlled oscillator that has a frequency range of 100 MHz to 100 GHz, making it well-suited for a range of applications requiring extremely precise clock signals.

The AX7DAF4-100.0000T is a voltage-controlled oscillator (VCO) that operates on an internal charge-pump active loop system, making it capable of achieving an ultra-low phase noise performance. This oscillator can be programmed over the 4-wire control SCI bus (SPI) protocol and also features a prescaler allowing for divided outputs.

The AX7DAF4-100.0000T has a wide range of applications, such as RF radios, satellite systems, high-speed datacom networks, and frequency synthesis. The extremely low jitter performance of this oscillator is ideal for securing reliable and long-term operation in frequency and phase applications, including synchronization and timing. It is also well-suited for Fibre Channel and Wireless LAN applications.

The working principle of the AX7DAF4-100.0000T oscillator is based on a voltage-controlled oscillator using active loop technology. A voltage-controlled oscillator consists of a voltage-controlled amplifier (VCA) coupled with an appropriate feedback loop, which in turn generates a stable frequency from its input signal. In this case, the input signal is an external voltage or current that is applied to a dedicated port on the oscillator.

The VCO generates a periodic output signal using an active loop system based on charge-pump technology. The oscillator uses an inductor-capacitor (LC) tank circuit to create the waveform, and its frequency is determined by the resonant frequency of the LC circuit. The voltage or current control signal is fed into the VCA, which modifies the voltage on the LC tank circuit linearly. This in turn changes the frequency of the output signal, thus allowing the oscillator to be frequency-tuned over a wide range.

The AX7DAF4-100.0000T oscillator is an ideal choice for applications such as RF radios, satellite systems, high-speed datacom networks, and frequency synthesis. Its ultra-low jitter performance makes it reliable and suitable for a wide range of applications requiring extremely precise clock signals. Furthermore, its 4-wire control SCI bus (SPI) protocol and prescaler provide flexible control and output, making the AX7DAF4-100.0000T oscillator an excellent choice for many applications.
