Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers are the application field of the CDC516DGG.

CDC516DGG is a miniature frequency synthesizer, a type of clock generator, providing a wide frequency range with low output jitter.

It is a fully integrated PLL solution, able to work with a single reference clock over a wide frequency range while providing best-in-class jitter performance in a tiny footprint.

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers have become a necessity for applications requiring both high speed and low power.

The CDC516DGG is designed for embedded, aerospace and medical applications where high speed, low power and wide frequency range are required.

It has a wide frequency range from 1000 kHz to 200 MHz, with a frequency stability of +/- 1 ppm and output jitter of less than 1 ps.

The key feature of the CDC516DGG is its ability to work with a single reference clock over a wide frequency range while providing best-in-class jitter performance in a tiny footprint.

The CDC516DGG utilizes a patented, Loop Filter Compensation technique that enables reliable clock signal spreading and jitter reduction over temperature and voltage.

The CDC516DGG also features a configurable output driver that supports a wide range of output logic levels, allowing the device to be used in a variety of systems.

The CDC516DGG also has an integrated power-on-reset that ensures that all outputs are held in a known state until the device is powered and calibrated.

The CDC516DGG supports both a Synchronous Serial Interface (SSI) and Inter-Integrated Circuit (I2C) bus, making it ideal for applications that require quick setup and flexible control.

The CDC516DGG is designed for use with FPGAs, DSPs, ASICs, and microcontrollers, and is available in 14-pin and 20-pin thin-profile surface-mount packages.

It is suitable for industrial, consumer, and medical applications where small size, low power, and low cost are essential.

The working principle of the CDC516DGG is similar to that of other clock generators and PLLs. The device consists of a phase-locked loop (PLL) with a phase-frequency detector (PFD) to compare reference and VCO clock frequencies.

The output of the PFD is used to control a voltage-controlled oscillator (VCO) whose output is phase-locked to the reference clock. The PLL maintains the phase relation between the reference and VCO clocks, thus allowing the CDC516DGG to produce a wide range of output frequencies.

In addition to the VCO, the CDC516DGG utilizes an adjustable loop filter to provide a low-noise output and to control the loop characteristics. A Digital Phase Detector (DPD) is also included in the device, allowing the user to program a wide range of output frequencies with minimal jitter.

The working principle of the CDC516DGG can be summarized as follows:

• A reference frequency is applied to the PFD.
• The output of the PFD controls the VCO frequency.
• The loop filter provides a low-noise output and controls the loop characteristics.
• The DPD is used to program a wide range of output frequencies with minimal jitter.

The CDC516DGG is designed to offer an integrated solution for applications requiring both high speed and low power. It provides a wide frequency range, low output jitter, high frequency stability and flexible control options.

The device is suitable for industrial, consumer, and medical applications where small size, low power, and low cost are essential.
