Oscillators

Oscillators are devices which convert dc inputs into ac outputs of various frequencies. The most common type of oscillator is the harmonic oscillator, which produces a sinusoidal output. These oscillators are used in a wide variety of applications, from radio and television broadcasting to consumer electronics and industrial automation. The SIT9121AC-2DF-25E156.25000Y oscillator is a specific type of harmonic oscillator that is designed to generate precise and stable frequencies in the audio range.The SIT9121AC-2DF-25E156.25000Y oscillator is a member of the SIT9121AC family of quartz crystal oscillators. These oscillators are designed to generate frequencies in the range of 25 MHz to 156.25 MHz. The oscillators are fabricated using high-performance, low-power CMOS technology, making them suitable for portable applications such as consumer electronics and wireless communication systems.The SIT9121AC-2DF-25E156.25000Y oscillator consists of two main circuits: the oscillator circuit and the buffer amplifier. The oscillator circuit consists of an oscillator cell, an initial condition circuit and a frequency-adjustment circuit. The oscillator cell is composed of an quartz crystal, a pair of inverters and an amplifier. The initial condition circuit is used to ensure that the oscillator is stable when it is first turned on. The frequency-adjustment circuit is used to adjust the output frequency with high accuracy.The output from the oscillator is fed into the buffer amplifier, which boosts the signal and reduces output impedance. The output of the buffer amplifier is a sinusoidal signal with a very low jitter of only 6 ps. The frequency accuracy of the SIT9121AC-2DF-25E156.25000Y oscillator is very high, typically 25 ppm over its full temperature range.The SIT9121AC-2DF-25E156.25000Y oscillator can be used in a wide range of applications, including digital synthesizers, radio and television receivers and transmitters, audio equipment, video equipment and telecommunications equipment. The low jitter and high frequency accuracy makes it an ideal choice for applications requiring precise and stable signal frequencies.
