LMK00804BPWR is a high-accuracy, low-jitter, low-skew, quad-output differential clock distribution buffer, which is often used in high-end servers, storage, and communication systems. This clock distribution buffer is suitable for applications that need high-performance, low-power, and high-precision routing of clock signals.

The LMK00804BPWR clock distribution buffer is capable of delivering four independent differential clock signals with up to 1600 MHz bandwidth performance. The clock jitter and skew of these outputs are guaranteed to be below 3 ps jitter and 500 ps skew, making it highly suitable for high-performance clock synchronization applications.

The differential outputs are designed for driving very sensitive high-speed clocks such as ECL, PECL, LVDS, and CML in applications such as ASICs, FPGAs, and high-speed ADCs and DACs. The device has a wide range of input frequencies from 2 kHz to 800 MHz and is capable of driving up to four outputs of up to 1600 MHz each. Due to its differential outputs, it can be used to distribute clock signals with low jitter and skew to multiple devices in the same system.

The LMK00804BPWR clock distribution buffer also features integrated LVCMOS circuit blocks, supporting LVCMOS differential inputs and outputs up to 5.5V. It also has an integrated voltage regulator that allows the device to be powered with a single +1.8V supply, saving power and space in the system.

The working principle of the LMK00804BPWR clock distribution buffer is fairly simple. It has two main stages: the input stage and the output stage. The input stage takes a differential source clock and converts it into a differential output clock by running it through a distributed circuit of resistors and capacitors. This produces a highly precise clock signal that is low jitter and low skew.

The output stage of the LMK00804BPWR then randomly distributes the differential clock signal across four individual outputs. The outputs are also equipped with reverse termination options, allowing the outputs to run at either low or high frequencies. This helps to further reduce any jitter or skew that may be present in the system, ensuring that all connected devices are receiving a highly accurate and reliable clock signal.

Overall, the LMK00804BPWR clock distribution buffer is an ideal choice for high-performance and low-power clock synchronization applications. By delivering four independent differential clock signals with low jitter and skew, it can provide highly reliable clock signals to ASICs, FPGAs, ADCs, and DACs with great efficiency. The device can be powered by a single +1.8V supply and offers both LVCMOS and differential outputs, thus making it versatile for various applications.
