The MK74CB218BRTR is a low jitter, 3V to 3.6V Fanout Buffer with three differential outputs. Designed specifically for applications needing low phase noise, this Clock Buffer has a total output skew of 6ps and a Bounding Rate of 40GHz minimum. With these features and its small footprint, the MK74CB218BRTR is perfect for high performance networking, computing and communications applications where a low jitter master clock source is required.

Clock Buffers, Drivers, are dedicated ICs optimized for buffering, distributing, and driving clock signals. This type of Clock Buffer is designed to reduce problem areas associated with sending high speed clock signals over long, fragile lines. Clock Buffers, Drivers, help to reduce noise, ground bounce, power line disturbances and variations in the impedance, resulting in improved system performance. They also help to reduce EMI and can provide up to 12 output signals with a single input.

The features of the MK74CB218BRTR include a clock frequency of up to 250 MHz, a rise and fall delay time of 19 ps, a maximum operating temperature of 85°C, an operating voltage range from 3.0V to 3.6V, and a total output skew of 6ps. It has adjustable drive strengths and is compatible with SSTL3, SSTL2 and LVCMOS clock formats. The maximum output load capacitance is 48 pF, and the package type is 8-lead SSOP.

The MK74CB218BRTR clock buffer is mainly used in networking and computing applications in which a low jitter master clock source is required. Some of these applications include public switches, high-speed networks, embedded processor systems, data communications systems, storage area networks, and data acquisition. The MK74CB218BRTR is ideally suited for these applications because it provides excellent signal Integrity, low power consumption, wide output frequency range, and low total output skew.

The working principle of the MK74CB218BRTR is very simple. It uses an external clock source to generate clock signals that are then passed through the buffer, providing isolation from the external source and allowing for a stable clock signal to be distributed to multiple components. The output signals from the buffer are then passed through different channels, with the exact number of channels depending on the specific device. In some cases, the same buffer may be used on multiple channels while in others, multiple buffers may be used, providing a variety of output signal configurations.

The MK74CB218BRTR also allows for adjustable drive strengths and increased flexibility by providing input frequency range of 15kHz to 250MHz. It is designed with chip-level ESD protection which helps to ensure long-term reliability. Finally, its small footprint makes the MK74CB218BRTR an ideal solution for high performance networking, computing and communication applications.

In summary, the MK74CB218BRTR is a low jitter, 3V to 3.6V Fanout Buffer with three differential outputs and is perfectly suited for networking, computing and communications applications where low jitter master clock source is required. Its features include adjustable drive strength, a total output skew of 6ps, a maximum operating temperature of 85°C, and a maximum output load capacitance of 48 pF. It is used to reduce noise, ground bounce, power line disturbances and variations in impedance in order to improve system performance, and its small footprint and chip-level ESD protection further enhances its appeal.
