Oscillators are electronic circuits that produce a periodic or oscillating electrical output signal, driven by an independent imput source. SIT8208AC-31-28E-38.400000X is one such oscillator.

Application Field

This device is well suited for the telecommunications industry, and is typically applied in the generation of clock signals. It can be found in multimedia communication systems, cellular transmissions, baseband and broadband applications, LAN and WAN systems, and oscilloscopes.

It is especially used in precision timing circuits, and very low jitter applications, such as line cards, gateways, DSL modems, router applications, and other consumer equipment. It can also be used for timing & synchronization applications, such as PLLs and FIFOs.

Working Principle

The SIT8208AC-31-28E-38.400000X uses a Pierce oscillator circuit design, which utilizes two amplifying elements to provide an inverted output signal. A crystal oscillator is used as the timing element, and a high-frequency output can be obtained—depending on the crystal used—by increasing the gain of the amplifying elements.

A feedback path is used to maintain the circuit oscillation. As the oscillation frequency increases, the gain of the amplifying elements decreases, and the feedback path is then adjusted to bring the frequency back to its set value according to the components used and the circuit design.

The device also includes a voltage-controlled resistor, which changes the oscillation frequency depending on the voltage that is applied to it. This allows the user to adjust the oscillation frequency, enabling the device to be used in different applications with different frequencies.

The SIT8208AC-31-28E-38.400000X is a highly stable oscillator, capable of maintaining high accuracy and precision under different conditions. This makes it especially suitable for applications where exact timing is required.
