Programmable Oscillators (POs) are a type of clock generator commonly found in digital applications. The SIT8008BIA3-18S is a particularly versatile PO, and is used in many digital circuits. It is designed for high-speed applications and offers flexible configuration options. This article will discuss the applications of the SIT8008BIA3-18S and how it works.

Applications

The SIT8008BIA3-18S is commonly used in many high-speed applications due to its low jitter and wide operating frequency range. It is suitable for a variety of high-speed communication protocols and is ideal for applications such as Gigabit Ethernet, optical communication and wireless communication. As a programmable oscillator, it is also useful for embedded system designs, where flexibility and application-specific requirements are paramount.

The SIT8008BIA3-18S is particularly suitable for applications where clock management is critical, as it can provide a reliable source of clock without requiring a roomful of dedicated clock generators. The on-board programmable control enables flexible configuration options and can be used to adapt the oscillator to different application scenarios. This makes it well-suited for broadcast and studios, where different parameters such as output frequency, phase jitter and duty cycle need to be tailored to the application.

How it works

The SIT8008BIA3-18S is based on a Silicon Labs SiT8008B frequency synthesizer. The SiT8008B is a highly-integrated device featuring an on-board Voltage Controlled Oscillator (VCO). This enables the oscillator to be programmed to output different clock frequencies, which can then be used as the reference clock for a system.

The SIT8008BIA3-18S features two outputs that can be configured separately. Each output has a wide tuning range of up to 200MHz, which can be programmed using a simple I2C interface. The on-board digital controller allows it to be tuned to frequencies greater than 200MHz with excellent phase noise performance. The phase jitter is also adjustable. Combined with the wide tuning range, this makes the SIT8008BIA3-18S ideal for high-speed applications.

The SIT8008BIA3-18S has a low power consumption of 1.5 mW and is housed in an ultra-small 5x5 mm package. This makes it perfect for space-constrained applications. The oscillator also features an on-board temperature compensation circuit that helps to improve frequency stability.

Conclusion

The SIT8008BIA3-18S is an ideal solution for applications that require a flexible, high-performance programmable oscillator. It features a wide tuning range and low jitter, making it suitable for a variety of high-speed communication protocols. The on-board programmable control allows the oscillator to be customized for different applications, and its small size and low power consumption make it perfect for embedded designs. As such, the SIT8008BIA3-18S is a valuable addition to any digital design.
