MK3721DLFTR is a clock generator and PLL (Phase-Locked Loop) frequency synthesizer integrated circuit that belongs to Texas Instruments Clock/Timing category and is designed for the specific purpose of providing the necessary clock signals and clock synthesizing functions for wireless base station and other applications with demanding frequency requirements. The device delivers 13 different frequencies ranging from 1.875GHz to 3.75GHz with a frequency resolution of 25KHz, and is compliant with ITU requirements providing all the features necessary to meet the needs of these demanding applications.

This device has a wide range of application fields such as digital broadcast receivers, wireless base stations and more. It is capable of generating several output frequencies from a single input reference frequency and can also be used for a variety of applications requiring multiple frequencies. The device is also suitable for systems with strict frequency stability requirements and for the elaboration of carrier-class products. In addition, the flexibility of the synthesizers allows for the generation of multiple output frequencies from a single reference frequency, making them ideal for use in multi-frequency systems.

The clock generator and PLL frequency synthesizer are composed of two essential elements: the clock generator and the PLL. The clock generator takes the reference frequency and feeds it into the PLL, which then produces the desired output frequency. As the frequency is adjusted, the PLL keeps the output frequency locked at the desired frequency. The MK3721DLFTR features a differential CLK0 clock output, allowing the generation of multiple output signals with a very high frequency resolution. It also features an integrated reference input buffer, allowing it to receive a wide range of operating voltages.

The functioning principle of the MK3721DLFTR clock generator and PLL frequency synthesizer is based on its ability to take in the reference frequency and generate a variety of output frequencies. It does this by taking an input reference frequency, for example, a crystal oscillator, and generating an output frequency based on the ratio of the two frequencies. The PLL then compares the input reference frequency to the output frequency in order to lock the output to the desired frequency. This helps maintain a certain level of frequency stability and prevents fluctuations in the output frequency.

The MK3721DLFTR is designed to be extremely flexible with respect to its operation. Its robust design allows for a wide range of different configurations of inputs, outputs, and settings. It also provides a very wide range of output frequencies that can be chosen to meet various application requirements. The ability to generate a number of output frequencies from a single reference frequency, as well as its superior integration and flexibility, make it an ideal option for use in multi-frequency systems.

In summary, the MK3721DLFTR is a clock generator and PLL frequency synthesizer from the Texas Instruments Clock/Timing category. It is designed for use in wireless base station applications and other demanding frequency applications, and provides a wide range of frequencies from 1.875GHz to 3.75GHz with a resolution of 25KHz. Its dual clock generator and PLL component functions together to generate a number of output frequencies from a single reference frequency, while also providing high frequency stability. Furthermore, the device features a wide input and output configuration and flexibility, allowing it to be easily adapted to different requirements.
