570KCB000118DG

Programmable Oscillators are sophisticated electronic components that offer the ultimate in flexibility, allowing users to adjust their timing dynamics to meet the needs of their application. The 570KCB000118DG is a Frequency-Locked Oscillator (FLO) sold as part of the Ultra-High Frequency (UHF ) product line from National Semiconductor. It is a cost-effective and space-saving solution for applications where targeting accurate maximum timing, frequency or phase shift is essential. The 570KCB000118DG comes with an impressive 2 GHz frequency range, 7-bit frequency resolution, a fractional-N divider and two Phase Lock Loops (PLLs). These components allow the 570KCB000118DG to precisely control certain aspects of system frequency with minimal effort from the user. The 570KCB000118DG Adaptive Loop Filter also offers a frequency range of 10 kHz to 500 kHz and provides adjustable locks to prevent unwanted frequency jams of the controlled oscillator.The 570KCB000118DG is designed to handle a wide range of applications in radio, satellite, and other communications systems. For example, it can be used in wireless base stations to ensure the optimal transmission of signals, in RF modules to provide precise timing for data acquisition and transmitting, and in microwave communications systems to ensure precise frequency and timing accuracy. The 570KCB000118DG also offers very low phase noise, which is essential for applications where minimum frequency jitter is required.The 570KCB000118DG is an ideal choice for use in communications systems, making it suitable for applications such as wireless access points, satellite tracking, Wi-Fi systems, and LAN systems. Furthermore, the 570KCB000118DG is an excellent choice for applications in robotics, where precise timing and frequency control is essential for smooth and efficient system operation.The working principle behind the 570KCB000118DG is quite simple. It combines two PLLs, a fractional-N divider and a special type of adaptive loop filter to provide precise frequency and timing control. The first PLL consists of a Voltage-Controlled Oscillator (VCO), a phase detector and a low-pass filter. This PLL is used to control the output frequency of the 570KCB000118DG, which is set by the user. The second PLL uses the same components but is used to control the phase of the 570KCB000118DG\'s output signal. When the phase of the output signal is adjusted, the 570KCB000118DG\'s output frequency will automatically adjust as well. The fractional-N divider is used to ensure that the 570KCB000118DG\'s output frequency is maintained despite variations in the input voltage. Finally, the adaptive loop filter is used to reduce phase noise and jitter, which is essential for certain high-precision applications with rigorous frequency and timing requirements.In conclusion, the 570KCB000118DG is an excellent choice for applications in radio, microwave, and wireless communication systems. Its combination of PLLs, a fractional-N divider and an adaptive loop filter provides precise frequency and timing control, making it particularly suitable for applications where frequency stability and low phase noise are essential.
