The CDCE72010RGCR is a quad-rate clock generator designed to reduce board space and enable up to four clock signals. The device generates clock signals of various frequencies from a single low-cost crystal. It is designed for high volume OEM applications, such as networking and storage systems. The device is also a full-featured Quadrant Clock Generator, with a wide range of outputs and clock options.

CDCE72010RGCR is based on a fully integrated clock synthesis core, where both the reference clock frequency and the divide clock are generated on a single chip. This integrated core is designed to meet stringent accuracy requirements while integrating a wide range of features and functions such as spread-spectrum clock generation, slew-rate control, and jitter attenuation. Various integrated dividers allow for clock outputs with a wide frequency range. Finally, a built-in PLL allows for multiple-reference clocks, which yield further design flexibility. In addition to the integrated core, the CDCE72010RGCR also features programmable input and output signal level, as well as input spread-spectrum control.

At the core of the CDCE72010RGCR is a Programmable Finite Impulse Response (PFIR) Digital Clock Synthesizer. The PFIR utilizes a transmit-only modulation scheme to divide the reference signal into a wide range of frequencies. The PFIR also provides a high-accuracy clock output with low jitter. In addition, the PFIR can also serve as a Digital Frequency Synthesizer, allowing for precision frequency multiplication and division. The PLL allows for synchronized change of output frequencies from the clock source, and can be used to design custom clock dividers.

The CDCE72010RGCR features an integrated Crystal Oscillator and Crystal Reference Amplifier that provide the required accuracy and stability. The oscillator operates at the desired frequency, while the amplifier provides the voltage and current necessary to drive the crystal. The integrated crystal oscillator also isolates the output from any noise and other external sources, allowing for a clean and stable output. The device also features a wide range of output formats, including differential, single-ended, LVCMOS, LVDS, and HCSL.

The CDCE72010RGCR has been designed to withstand challenging environmental conditions, and has been tested to withstand temperatures as low as -40°C and as high as 85°C. The device is rated at a minimum +3.3V and maximum +3.6V supply voltage. It also features over-voltage detection and protection to ensure safe operation.

The CDCE72010RGCR is an ideal clock generator for many high-volume applications. The device’s integrated core, wide frequency range, and numerous features put it at the top of its class. The integrated oscillator and crystal reference amplifier also ensure that this device can provide an accurate and stable clock signal, no matter what the conditions. The wide range of output formats make the device suitable for a range of different designs, and the built-in PLL allows for multiple reference clocks to be used. Finally, the device’s temperature range and over-voltage detection and protection are ideal for use in challenging environments.
