SIT8208AI-31-18S-40.000000Y oscillator is widely used in consumer electronics, communications, computations, industrial controls, automotive infotainment and medical devices. It is designed to generate a precise and stable clock signal with low jitter performance. The oscillator is ideal for applications such as micro controllers, FPGA, video decoders, USB ports, Ethernet ports, alarm systems, consumer electronic device, automotive infotainment, etc.

Working Principle

The SIT8208AI-31-18S-40.000000Y oscillator works by using two capacitors and two inductors in a balanced arrangement to generate an oscillation across the inductors. The capacitors provide high frequency capacitance which energizes the inductors, while the inductors store energy that is converted to electrical current to initiate the oscillation. The oscillator has a high degree of linearity and stability over a wide frequency range, which makes it ideal for applications requiring low-noise, low-jitter and low-power performance.

The oscillator uses two series oscillator amplifier sections consisting of an I/O Buffer, oscillator feedback transistor, active current limit, buffered input, and warm-up transistor. The oscillator amplifiers are connected to the two-capacitor, two-inductor (LC) oscillator network, as well as to the power and ground supplies. The LC oscillator provides the balancing of the capacitor and inductor elements which induces the oscillation. The oscillator amplifier provides the gain required to sustain the oscillation.

The oscillator’s frequency of operation is determined by the characteristics of the LC network, such as the self-resonance frequency of the inductors. The oscillator frequency is adjustable over a range of frequencies by varying the capacitors and inductors used in the LC network. The frequency of the oscillator can be further adjusted by varying the input voltage to the LC network. This adjustability makes the oscillator suitable for applications where frequency accuracy and stability are essential.

Conclusion

SIT8208AI-31-18S-40.000000Y oscillator is a low-power, low-noise and low-jitter oscillator that is used in a variety of applications. The oscillator works by using two capacitors and two inductors in a balanced arrangement to generate an oscillation that is adjustable over a range of frequencies. The design of the oscillator allows it to provide excellent linearity and stability over a wide range of frequencies and makes it ideal for applications requiring low-noise, low-jitter and low-power performance.
