Oscillators are used in many fields, from communication systems to signal processing. They are typically used to generate oscillating signals, either for use in digital processors, as a time source, or as an accuracy reference. Oscillators can be broadly divided into two types, analog and digital.Analog oscillators rely on feedback to generate a repeating waveform. Oscillations may be generated by feedback from a circuit consisting of an amplifier and an electronic component such as a resistor, a capacitor, or an inductor. The feedback generates a signal that is amplified and then fed back into the circuit. As the feedback builds, the amplifiers gain gradually increases until an oscillation is produced. This feedback method is often used in audio applications as it allows for rapid oscillations at audio frequencies.Digital oscillators rely on digital logic elements such as gates or counters to generate a repeating signal. A digital oscillator may be programmed to generate a periodic duty cycle that can be used to drive a processor or other digital logic circuit. Digital oscillators may also be used to create a clock for a digital system and as such they are often used to provide a timing reference for sampling and control operations.The AX7DAF4-74.5000T is a programmable Digital Oscillator which provides a precise and low-jitter timing source for digital and analog components. The oscillator is built on a compact, double-sided, 4-layer PCB, and is rated to work at temperatures from –40°C to +125°C. The unit can be programmed with a frequency up to 74.5000 MHz, with 0.1 mV of accuracy. Additionally, the AX7DAF4-74.5000T has a wide frequency range from 10 kHz to 74.5000 MHz and is designed to provide a minimum jitter of 2.5 ps RMS, thus making it suitable for a wide range of digital applications such as phase-locked loops, high-speed audio systems, and radio base stations. It is also a highly stable clock source, with a low drift of 0.02 ppm/°C.The AX7DAF4-74.5000T utilizes a fractional-N phase-locked loop (PLL) with a programmable output divider to generate precise frequencies up to 74.5000 MHz. The PLL obtains a reference frequency signal from an oscillator, usually with an external crystal, and compares it to the internal frequency. The PLL then adjusts the reference frequency with a digitally-programmable divider to exactly match the reference. This provides an accurate low-jitter clock source, with fast response to changes in the reference frequency.In addition, the AX7DAF4-74.5000T features an enable/disable function, a power-down input, and an optional synchronization input. The enable/disable input allows for easy control of the output frequency and the power-down input can be used to reduce power consumption when the system is not in use. The synchronization input allows it to be used as a synchronous clock source for digital logic, providing an accurate time reference for digital systems.The AX7DAF4-74.5000T is a highly precise digital oscillator with a wide range of applications in communication systems, signal processing, and timing applications. Its wide frequency range and low jitter makes it suitable for a variety of digital applications and its low drift and enable/disable control make it a reliable and cost-effective source of high-accuracy oscillations for many applications.
