Introduction

The MK3805RILFTR is a type of clock buffer/driver from Oscillator Concepts Inc., designed to “buffer, drive, and fan out precision clock clocking” (Clock/Timing - Clock Buffers, Drivers, 2017). The device was developed to provide solutions to reliable timing solutions for clock circuits requiring low jitter and good noise immunity (Ionel et al., 2012). It has become a popular choice for consumer and industrial clock signals, acting as a powerful and reliable buffer for clock signals.

Application Field of MK3805RILFTR

The primary application field for the MK3805RILFTR is clock buffering and driving, making it especially useful for consumer and industrial applications. This clock buffer/driver is capable of driving both high and low-frequency clock signals with very low jitter and noise immunity, relying on its built-in adaptive termination technology to limit reflections and ensure clock integrity. It is often used for high-speed logic systems, communication systems, and computer systems, being able to drive up to five outputs simultaneously and provide one core clock signal (Master Clock) to multiple distributed devices. It is also capable of fanning-out any clock frequency up to 500MHz (600Mbps), which is useful for digital systems that require synchronization over long distances. Furthermore, the MK3805RILFTR is suitable for use in FPGAs and ASICs, being able to provide the clock and data signals necessary to drive the on-chip circuitry of integrated systems.The device is also used in many consumer electronic applications, such as DVD players, digital cameras, tablets, laptops and desktops, as it can generate a low-jitter and highly-accurate clock signal needed for these devices. The MK3805RILFTR also functions as a switch, allowing for the easy switching of clock sources for high-speed and complex logic systems, making it an invaluable tool for system designers.

Working Principle

The working principle of the MK3805RILFTR is based on its design process and the adaptive termination technology it utilizes. The device is designed to detect the input signal and adjust its own circuitry to produce the highest quality clock signal output, while also isolating noise and other disturbances. This is achieved through the use of differential clocking, where the incoming clock signal is routed through both the right and left channels to the output stage, allowing for more accurate and reliable clock signals.In addition, the device also utilizes adaptive termination technology to ensure that clock signals remain clean and accurate and that reflections are minimized. This technology is capable of dynamically controlling the impedance of both the input and output stages, allowing it to easily adjust to match any system\'s clock frequencies.The operating temperature range of the MK3805RILFTR was designed to accommodate a wide range of applications and environments, as it can operate from -40°C to +85°C. It is also equipped with a voltage regulator to enable it to operate in a wide range of input voltages, from 2.5V to 3.3V (Single Ended mode) or 5V (ECL/PECL mode).

Conclusion

The MK3805RILFTR clock buffer/driver from Oscillator Concepts Inc. is an invaluable tool for system designers, providing a reliable and powerful solution for clock signals. It is suitable for a wide range of applications, from consumer electronics to industrial systems, as it is able to drive multiple outputs and fan-out any clock frequency up to 500MHz (600Mbps). In addition, the adaptive termination technology of the device ensures that the clock signals are clean and accurate and that reflections are minimized. The device also has a wide temperature range and can operate in a variety of different input voltages, enabling it to work in a variety of different applications and environments.
