CDCF5801ADBQG4 clock generator, also known as a Phase Locked Loop (PLL) frequency synthesizer, is a complex IC integrated circuit used to generate precise clock signals running at varying frequencies. The device is capable of producing outputs of different frequencies that can range anywhere from 0.03 MHz to 600 MHz. It requires an input reference clock frequency of between 8 – 20 MHz and depending on the user’s specific application—50% or 33.3% duty cycle—, the output frequency can be adjusted accordingly. One of the most unique features of the device is that it is pin and function compatible all CDCF5801 products.

A main application area of the CDCF5801ADBQG4 is in-circuit board testing using JTAG compliance methodologies. During test and debug operations, precise, independent clock signals of various frequencies and duty cycles must be produced; the CDCF5801ADBQG4 is the perfect choice for this task. When used to test boards, the device can generate an adjustable clock frequency of 10 MHz to 50 MHz, with a duty cycle of 33.33%. The clock frequency range of operation is suitable for various types of JTAG compliant instruments.

The CDCF5801ADBQG4 combines a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) to generate clock signals with a precise frequency. The device utilizes its PLL circuit to track a reference clock signal provided by an input device and then applies a reference duty cycle (50% or 33.3%) to generate the output clock signals. Using its VCO circuit, the output frequency can be adjusted to within a wide range, depending on the onboard user setting.

The center operating frequency of the Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers CDCF5801ADBQG4 can be programmed between 125 kHz and 600 MHz, with a maximum frequency resolution of 300 kHz. Moreover, the device outputs are fully independent, meaning the user can set up different frequencies on each output; the multiple outputs can range from 0.03 MHz to 600 MHz.

With its PLL-VCO circuitry and wide ranging frequency outputs, the CDCF5801ADBQG4 is an ideal choice as a clock generator for applications designing and developing circuits for high speed digital areas. Additionally, the CDCF5801ADBQG4 can support a myriad of different communication protocols such as Universal Serial Bus (USB) 2.0, Ethernet and Serial ATA (SATA) technologies, making it an all-in-one clock generator solution.

In summary, the CDCF5801ADBQG4 outclasses its competitors in terms of its frequency outputs, adjustable duty cycles and versatility. By utilizing an onboard programmable PLL and VCO circuitry, the device supports a variety of applications requiring precision independent clock signals. The CDCF5801ADBQG4 can generate frequencies ranging from 0.03 MHz to 600 MHz and is an optimal choice for device testing and high speed digital applications.
