The CDCF5801DBQRG4 is a high-performance clock generator and frequency synthesizer produced by Texas Instruments. It is used for high-speed communication, industrial, and consumer applications. For example, it can be used for SONET/SDH high-speed optical communication systems, Video and high speed networking applications, as well as DRAM memory bus and chipset applications.

The CDCF5801DBQRG4 includes both a low-phase-noise, single-ended output and a low-power, differential output. It offers a wide frequency range from 10 MHz to 180 MHz and a highly-accurate synthesis/generation that is able to provide both a Type I and Type II jitter profile. The Type I jitter profile has an overall jitter of ±1dB while the Type II jitter profile is designed to limit harmonic and sub-harmonic components. The CDCF5801DBQRG4 also features a wide power supply range of 1.95V to 5.25V and selective disable capability to turn off any of the two outputs.

The CDCF5801DBQRG4 is designed to use Synchronous Frequency Synthesis (SFS). SFS is a technique used to synthesize a wide range of frequencies using internal phase-locked loop (PLL) and digitally-controlled oscillator (DCO). When the PLL is locked, it generates a reference signal at the target frequency to be used for the DCO. The DCO then synthesizes the output signal at the desired frequency, thus providing a high-accuracy signal. This technique also allows for the adjustment of the synthesized output frequency with a computer-controlled software.

Furthermore, the CDCF5801DBQRG4 has an integrated control register, which allows for configuration and control of the output frequency as well as power management modes. This integrated support also allows for remote programming or communication over a standard bus. Designers interested in using the CDCF5801DBQRG4 should understand the principles of PLLs, frequency synthesis, and clock generation.

The CDCF5801DBQRG4 is a powerful clock generator and frequency synthesizer useful for high-speed signal applications. Its capability to output highly-accurate signal, selectable disable operation, and integrated control register make it an ideal choice for signal processing platforms. Its wide frequency range and low-power, differential output also make it suitable for a variety of applications, from consumer electronics to industrial product designs.
