CDCF5801ADBQ is a device that provides a fully integrated solution for clock and timing applications. It is a versatile clock synthesizer that combines a wide range of features in a small package. It provides a low jitter, low power, high frequency clock source for microprocessor and FPGA designs.

The CDCF5801ADBQ is a low power, low jitter programmable clock generator. It consists of an input, reference, output and prescaler section. The input section allows for LVDS/LVCMOS inputs with selectable slew rates up to 400MHz. The reference section consists of an inbuilt 2.5MHz reference clock and a 50MHz clock signal from an onboard crystal oscillator. The output section allows for out-of-the-box frequency selection for many common-mode outputs such as LVDS, LVCMOS, and HCSL. The prescalers allow for additional frequency divisions up to 16x for finer frequency control.

The working principle behind the CDCF5801ADBQ is based on the concept of frequency multiplication and division. A reference clock signal is fed into the device from an external source. This signal is divided by a programmable divider and then multiplied by a programmable factor to generate an output clock signal with a frequency which is a multiple or a fraction of the reference signal. The divider and multiplier are combined together to form a programmable digital PLL (DPLL) or Phase Locked Loop. The DPLL is used to produce and lock output clock frequencies to a predetermined value.

The CDCF5801ADBQ has a variety applications in clock and timing applications such as high speed HDD and storage system, automotive audio, and other digital applications. In storage systems, the device is used to generate high speed clocks for the logic circuits and for the front-end SAS and SATA controllers. The clock generator is also used in high-speed communications links such as 10 gigabit Ethernet and optical communication links. In audio applications, the CDCF5801ADBQ is used to generate the reference clocks for ADC and DACs. It is also used to provide a low jitter, low power clock source for microprocessor and FPGA designs.

The CDCF5801ADBQ is a reliable and low-power solution for clock and timing applications. It provides customers with a fully integrated solution for their applications. With its onboard reference clock and programmable dividers, the device provides flexibility and a high degree of customization for the system designer. It is a cost-effective solution that can be used in a wide range of applications ranging from storage systems to automotive audio.
