621MLF is one of the popular frequency-Locking Clock buffer in the clock/timing industry. It is widely used in computing, mobile communications and consumer electronics. This type of clock buffer can solve some system layout and performance issues with its frequency-Locking characteristics, great processing speed and low power consumption. In this article, we\'ll discuss the application field and working principle of 621MLF.

First, let\'s talk about its application field. 621MLF is mainly used in the consumer electronics industry, especially in communications and computing. It is necessary in mobile network transmission, communication routers, embedded systems, handheld devices and integrated consumer electronics. Besides, 621MLF is also applicable in hard disk drivers, HCI (Human Computer Interface) and large scale integration of consumer electronics.

Next, let\'s explain the working principle of 621MLF. 621MLF is designed to lock its output frequency at twice the reference frequency. That is, when its input frequency changes, the frequency of the output signal will still remain the same. This feature is achieved by the embedded Select-A-Fuse-Locked Loop Control Technology, which uses an on-chip capacitive-sense circuit to monitor the on chip capacitive charge and to modulate the internal voltage-controlled oscillator. When an external reference frequency is applied to the 621MLF input, the internal charge is adjusted accordingly, and the control voltage is adjusted accordingly to lock the phase and frequency. The 621MLF also contains two variable-reset functions that can be used to adjust the reference frequency and phase as needed.

Furthermore, the 621MLF has been designed for high operating efficiency and low-power consumption. It operates from a single +3.3V supply, providing power savings of up to 40% over traditional clock buffer designs. In addition, the Select-A-Fuse-Locked Loop Control Technology ensures a low jitter performance. This ensures fast and reliable performance in applications that require synchronization of clock signals.

In conclusion, 621MLF is the ideal solution for communication and computing applications that demand frequency-Locking performance. With its fast processing speed, low power consumption and Select-A-Fuse-Locked Loop Control Technology, 621MLF provides a cost-effective way to solve system layout and performance issues. Consequently, it is popular in the clock/timing industry and is widely used in communications and computing.
