SIT9005ACL2G-18NP

Programmable oscillators are a type of oscillator that allow users to change the signal frequency output digitally, or use a range of frequencies, by means of programming. The SIT9005ACL2G-18NP is a miniature, low cost and high performance programmable oscillator that is used in many applications. This article will discuss the application field and working principle of SIT9005ACL2G-18NP.

Application Field

The SIT9005ACL2G-18NP supports a wide range of frequencies, ranging from 1MHz to 50MHz, and is suitable for a variety of applications, such as imaging systems, automated test equipment, radio frequency and microwave communications as well as general timing systems. Its low profile, 1.2mm height, makes it suitable for space constrained applications, and its low power consumption, 8mA at 16MHz, makes it ideal for power constrained systems. It is also available in a range of package options, including LCC and LLP, to meet customer requirements.

Working Principle

SIT9005ACL2G-18NP is a quartz crystal oscillator device. It is composed of a quartz crystal resonator and a CMOS or TTL Programmable Logic Circuit (PLC). The quartz crystal resonator acts as a frequency-determining component, while the PLC determines the type of output signal and frequency range. The PLC also allows for programming of frequency, waveform, pullability and jitter. The SIT9005ACL2G-18NP also features an amplitude control circuit, allowing for a selectable output waveform.

The SIT9005ACL2G-18NP utilizes a simple serial programming interface (SPI), making it highly flexible and programmable. It has an integrated voltage-controlled temperature-compensated crystal oscillator (VCTCXO), as well as robust jitter characteristics and low phase noise and close-in jitter. This makes the SIT9005ACL2G-18NP suitable for applications requiring high performance and reliable timing.

Conclusion

The SIT9005ACL2G-18NP is a miniature, low cost and high performance programmable oscillator used in a variety of applications. It supports a wide range of frequencies, from 1MHz to 50MHz, and is available in a range of package options, including LCC and LLP. It also features an integrated voltage controlled-temperature compensated crystal oscillator and robust jitter characteristics. This makes the SIT9005ACL2G-18NP an ideal choice for applications requiring low power consumption, high performance and reliable timing.
