Oscillators

Oscillators are circuits that are designed to output a steady signal at a certain frequency. Some oscillators can range to an output frequency of anywhere from the audible range up to high frequencies in the Gigahertz range. Depending on the type of oscillator, these signals can then be used as a low frequency clock source, a reference signal or a radio frequency transmission.

510ABA10M7000AAG

The 510ABA10M7000AAG is a programmable and highly stable oscillator. It is primarily designed for use in higher frequency applications requiring precise and accurate frequency generation over a wide temperature range. It is constructed with a ceramic package, reducing its size and weight, while providing good shielding characteristics. The device also offers a wide adjustment range of ±30 ppm.

Application Field

Given its programmability and stability, the 510ABA10M7000AAG is well-suited for applications that need precise frequency generation and temperature compensation. These include low frequency clocks in wireless systems, satellite navigation systems, and automotive applications, as well as frequency references in GBAS, electronic system simulators, and video game consoles. The device is also well-suited for some healthcare products such as glucose meters and pulse oximeters.

Working Principle

The 510ABA10M7000AAG utilizes a phase-locked loop (PLL) based configuration to generate stable and precise output frequency. The PLL is composed of a voltage-controlled oscillator (VCO), a phase and frequency detector (PFD), a low pass filter (LPF), and a reference divider. The PLL maintains a constant frequency ratio between the input and output signals. The PLL starts by detecting the input signal frequency and phase using the PFD, and then adjusts the output frequency of the VCO to match the output of the PFD. The LPF then filters the output, producing a clean signal. The reference divider divides the reference frequency down to the desired output frequency. The quality of the output signal depends largely on the stability of the reference frequency. With its excellent stability and temperature compensation characteristics, the 510ABA10M7000AAG provides the accuracy and precision required for such high-precision applications.
