The MC100H641FNR2 clock/timing buffer is a driver that provides 2MHz rated full-frequency translation or fan-out product. It is well-suited for applications that require low noise and low power designs. This product is ideal for the clock buffering requirements of distributed clock networks that carry low frequency signals, as well as for single-ended transmission lines requiring excellent signal integrity. The H641 is fabricated with a 3-bit wide common sink structure which enables the device to operate over a wide input range from the standard to a high-speed clock rate.

The MC100H641FNR2 works by accepting a single-ended input signal, which is then equalised by a variable gain amplifier (VGA) and amplified to the desired output level. The VGA ensures that the signal is transmitted at an adequate voltage level. This also provides noise and jitter improvements relative to the original signal.

The device then sends the signal to an output stage, which contains an output buffer. This buffer produces a clean, low noise, low power output signal. The buffer also helps to reduce electromagnetic interference (EMI) because it minimizes the risk of radio interference from the output signal. The output is then buffered and sent to a fan-out buffer, which further amplifies the signal, buffers it, and sends it to multiple outputs for further fan-out.

The MC100H641FNR2 provides excellent line termination, with the appropriate pull-up and pull-down feature. This ensures that the signal is received at the desired level and helps to minimize reflections and overshoot. Furthermore, the device can also be used in Clock Multiplication applications, where the input clock is first divided and then outputs several copies of the clock signal with different frequencies. These clock signals can then be used in data communications and other high speed applications.

The MC100H641FNR2 can be used across a variety of applications, with its outstanding signal integrity properties making it ideal for clock buffering and fan-out applications. This product is particularly useful in distributed-clock networks, where low frequencies are essential, as well as applications requiring single-ended transmission with excellent signal integrity.
