The MC100EL11DTR2 is a EPIC™-based, integrated, high-performance differential fanout buffer designed to support a wide range of applications. This type of device is typically used in Clock/Timing applications as a clock buffer, driver, or both, depending on the application requirements. Its main purpose is to drive multiple outputs from a single input, with little to no signal-to-noise interference. This is accomplished by providing low output capacitance, high input impedances, and a low output-to-output skew, allowing signals to be transmitted at a higher frequency without suffering from noise. Additionally, the device is a highly integrated device, meaning all the components and circuitry are built on one chip, offering excellent energy efficiency and operational longevity.

Applications

The MC100EL11DTR2 is well suited for applications in which clocks and timing signals need to be distributed. It is commonly found in communications and networking systems, as well as portable electronics, server and storage systems, medical imaging and instrumentation, military and aerospace, and many other industries that require reliable and high-speed clock buffering and driving. The features offered by the device enable these systems to function reliably and with very low latency.

Working Principle

The MC100EL11DTR2 is based on EPIC (Enhanced Performance Inverter Chain) technology, which allows for the buffering of clock and timing signals in an efficient manner. It utilizes an inverter chain with feedback, allowing the device to simultaneously achieve a high-speed response and low output-to-output skew. First, the clock and timing signals are received as digital signals at the input. The signals are then propagated through the inverter chain, where each stage is connected to the next. Since each stage has a small delay associated with it, the overall propagation delay of the chain is less than that of a single stage. The outputs are generated once the input signals reach the final stage of the inverter chain, and the outputs are transmitted at the same frequency of the input signals.

The MC100EL11DTR2 also uses a biasing network to ensure tight impedance matching between the input and outputs. This biasing network also enables the device to drive multiple outputs while maintaining low output capacitance. The output current and impedance matching can be adjusted by changing the value of the biasing network components, allowing the device to be optimized for each application.

In addition to buffering and driving, the MC100EL11DTR2 also provides advanced power management capabilities. It includes a power-down mode, which allows the device to reduce power consumption when not in use. This feature is especially useful in battery-operated applications, where it can extend the battery life. The MC100EL11DTR2 also includes thermal-protected outputs, ensuring the device is not damaged by excessive current or temperature.

Conclusion

The MC100EL11DTR2 is a highly integrated clock buffer, driver, and power management device designed for use in Clock/Timing applications. It offers excellent performance in terms of low output-to-output skew and high frequency response, and its integrated components make it an energy-efficient choice. Additionally, its biasing network and thermal-protected outputs provide the necessary features for reliable operation in a variety of applications.
