Programmable oscillators are flexible, easy to use devices that provide clean and accurate signal sources for various applications, ranging from clock and timing control to signal synchronization and communication. Because they are programmable, they are an ideal choice for applications requiring precise control of signal frequency, stability, and power consumption, such as the SIT1602AIE8-30E. This article will explore the application field and working principle of the SIT1602AIE8-30E.

Application Field

The SIT1602AIE8-30E is a programmable oscillator designed for high-speed, low-power, low-skew systems. It requires a single 3.3V supply and offers high immunity to noise, vibration and external jitter. This device easily generates a wide range of frequencies from 1Mhz to 30MHz, making it suitable for a variety of high-speed applications such as Ethernet, DDR, and FPGA.

This programmable oscillator has an on-chip voltage controlled oscillator (VCO), which produces up to 30MHz of continuous frequency operation over a wide range of output voltages. Furthermore, the device utilizes a charge pump voltage regulator (CPR) to ensure stable power performance. Thanks to its integrated circuit design, it provides improved noise immunity compared to discrete components. Moreover, it has a low jitter performance, which is essential for high-speed communication protocols. This makes the SIT1602AIE8-30E an ideal choice for a host of high-speed applications.

Working Principle

At the heart of the SIT1602AIE8-30E is a voltage controlled oscillator (VCO). This oscillator uses an external resistor to control the frequency and stability of the output signal. The VCO has a voltage-controlled tuning range of up to 30MHz and can be programmed with a simple voltage signal. This signal is then fed into the Control Loop, which adjusts the current supplied to the VCO such that the desired frequency is produced.

The VCO is coupled to the output buffer, which provides a low-skew output signal through one of the two output pins. The output buffer is designed to drive low-impedance loads, offering good noise immunity and reducing the possibility of clock cycle irregularities due to external interference. The charge pump voltage regulator (CPR) is used to ensure a stable power supply to the oscillator. It provides a steady 3.3 Volt output voltage, even when the supply voltage may fluctuate.

Additionally, the SIT1602AIE8-30E utilizes an advanced temperature compensation process to ensure high-accuracy performance over a wide temperature range. This process uses on-chip temperature sensors to adjust the output frequency in the event of a temperature excursion.

Conclusion

In conclusion, the SIT1602AIE8-30E is a programmable oscillator designed for high-speed, low-power, low-skew systems. It offers a wide range of frequency options from 1Mhz to 30MHz, making it ideal for a range of applications. It utilizes a voltage controlled oscillator (VCO) in combination with a charge pump voltage regulator (CPR) to ensure high-accuracy performance, even under fluctuating power conditions. It also offers an advanced temperature compensation process to ensure accuracy over a wide temperature range. For these reasons, the SIT1602AIE8-30E is an excellent choice for a variety of high-speed applications.
