CDCVF111FNR

The CDCVF111FNR is a high-performance clock buffer and driver, created for applications that require the distribution of clock signals with low-skew, low-jitter, and low-power consumption. It is designed to improve system performance, power savings, and signal integrity. With a back-drive capability, its input-to-output delay is minimized, while also providing a wide range of operating frequencies. Additionally, its power consumption is reduced by up to 18% compared to a traditional clock buffer.

The CDCVF111FNR is used in applications that require precise distribution of high-speed clock signals with minimal physical space and reduced power consumption. This clock buffer is designed to drive low-skew, low-jitter, low-power clock signals into multiple load points without adding complexity. In the presence of long boards, such as those with PCIe slots, the back-drive capability with low-skew is especially important. These applications are usually in the fields of industrial, medical, and gaming.

The CDCVF111FNR clock buffer is based on a differential-feedback design, enabling it to achieve low skew and high-precision control. The clock buffer is composed of four individual drivers, each comprising dynamic-leveling logic, a voltage-controlled current source (VCCS), and four multiplexers. This balanced configuration of drivers helps reduce contamination of clock signals as signals are transmitted from one end to the other. The buffer includes a dielectric isolation feature, which prevents electromagnetic coupling to external environment and reduces the risk of signal degredation. Additionally, the clock has the ability to accurately control input-to-output delays, making it suitable for long-reach applications.

The CDCVF111FNR clock buffer is designed to support a range of frequencies, from 0.25MHz to 200MHz. It is capable of providing up to eight independent clock outputs with up to 18dB reduction in power consumption. For example, when compared to a traditional 2-output buffer, the CDCVF111FNR can eliminate 10mA of current draw. With its ability to support PCI Express, the CDCVF111FNR can help future proof applications with support for PCIe 3.0. This device also implements many control modes, such as spread spectrum, and it is RoHS compliant for added support for green projects.

The CDCVF111FNR is suitable for a wide range of applications, as it is designed for low-power, low-jitter, and low-skew performance. Its back-drive capability, combined with its wide range of operating frequencies, make it especially useful for applications that require the transmission of clock signals with minimal physical space and reduced power consumption. When compared to traditional clock buffers, the CDCVF111FNR can help reduce power consumption by up to 18%, thus providing a greater system energy efficiency.
