Programmable oscillators are an important type of electronic component used in a variety of electronic applications. The SIT9005ACL2G-33EP is a programmable oscillator that is available in a wide variety of packages and configurations. This article will provide an overview of the SIT9005ACL2G-33EP, including its application field and working principle.

Application Field

The SIT9005ACL2G-33EP is a two-terminal, low-jitter, programmable oscillator designed for use in a variety of applications. It is ideal for use in high-speed communications applications such as 10Gbps Ethernet and high-definition audio equipment. It is also suitable for use in medical, aerospace and defense applications that require precise timing control. The oscillator is available in a range of configurations, including hermetic and radiation-tolerant packages, allowing it to be used in a variety of challenging operating environments.

Working Principle

The SIT9050ACL2G-33EP is a phase-locked loop (PLL) oscillator. A PLL oscillator uses two voltage-controlled oscillators to generate a precise clock signal. A reference oscillator produces a fixed reference frequency, while a phase detector compares the reference oscillator’s output with that of a voltage-controlled oscillator. The phase detector adjusts the frequency of the voltage-controlled oscillator until its frequency matches that of the reference oscillator. The output of the voltage-controlled oscillator is the final clock signal produced by the PLL oscillator.

The SIT9050ACL2G-33EP is designed to meet stringent jitter requirements. In addition to a low jitter (<1.5ps), it is designed to provide an excellent power-versus-performance balance across a wide supply voltage variation. It is equipped with an advanced on-chip spread spectrum capability, allowing clock jitter to be spread over a range of frequencies and resulting in improved system performance.

The SIT9050ACL2G-33EP also features an integrated temperature sensor that monitors the die temperature and allows the oscillator to be tuned for increased accuracy over a temperature range. Furthermore, the oscillator is capable of generating multiple outputs, including single-ended, differential and spread-spectrum output.

The SIT9050ACL2G-33EP is also equipped with an integrated voltage regulator, which allows it to provide a steady supply of power over a wide voltage range. This eliminates the need for an external voltage regulator and ensures accurate performance over the specified operating range.

Conclusion

The SIT9005ACL2G-33EP is a low-jitter, programmable oscillator designed for use in a variety of demanding high-speed, telecommunications and medical applications. Its on-chip spread spectrum capability, temperature sensing and voltage regulator, make it an ideal choice for applications requiring precise timing, steady power supply and low clock jitter.
