5P49V5901A765NLGI Application Field and Working Principle

The 5P49V5901A765NLGI chip is an ultra-low-jitter SPLL/MCM clock generator used in high-performance networking systems, server and Telecom applications. It provides an ideal solution to generate multiple high-frequency and ultra-low-jitter clocks for 100G, 50G and 200G Ethernet, telecom and data center servers, storage and other high-end computing products.

The 5P49V5901A765NLGI generator is a high-performance, low-power integrated circuit, employing an advanced single-microcontroller-based phase-locked loop (SPLL) design. The single-microcontroller-based loop eliminates the need for traditional phase-locked loop circuits, reducing complexity and cost. The circuit can generate multiple clock signals with a jitter of less than 10ps, and an stability of +/- 20ppm.

Working Principle of 5P49V5901A765NLGI

The 5P49V5901A765NLGI generator uses an advanced SPLL architecture to synthesize multiple low-jitter, high-stability clock signals at specified frequencies. It consists of a phase-frequency detector (PFD), a charge pump, a loop filter, and a voltage-controlled oscillator (VCO). In operation, the PFD compares the inputs signals, synchronizing the internal VCO to the desired reference frequency. The charge pump circuit then converts the phase difference information from the PFD into an adjustable current, based on which the loop filter generates an analog voltage. This voltage is then fed to the VCO to control its output frequency. The SPLL further reduces jitter and improves frequency stability by minimizing the gain of the PFD and introducing additional dampening in the VCO.

5P49V5901A765NLGI Applications

The 5P49V5901A765NLGI chip can be used in a wide range of industrial and consumer applications, including telecom, data centers, servers, storage, and high-end computing equipment. It is ideal for applications that require multiple low-jitter, high-stability clock signals, such as 100G, 50G and 200G Ethernet, and other high-end Ethernet applications. It can be used to provide a single reference clock for multiple devices, eliminating the need for multiple clock sources and further streamlining the design process. The chip is also suitable for synchronous data-bus applications, such as memory and ASIC interfaces.
