Clock/Timing technology is an essential component of today’s electronic devices. From common consumer electronics to communication infrastructure and medical equipment, it is used in virtually every industry. The 813N252CKI-02LF is a reliable, high-performance clock generator and frequency synthesizer that meets the demanding needs of today’s digital world. In this article, we will discuss the 813N252CKI-02LF’s application field and working principle.

The 813N252CKI-02LF is specifically designed for high-speed, high-precision clock generation and frequency synthesis operations. It offers a wide range of output frequencies, from 13 to 252MHz, that can be precisely tuned over a wide range of temperatures. The device supports a wide selection of input reference frequencies, ranging from 2.5MHz to 35MHz. It also has a power down feature for power savings when not in use. Additionally, it features an integrated Phase-Locked Loop (PLL) for improved noise jitter and maximum clock stability.

In addition to its excellent performance specs., the 813N252CKI-02LF is also designed for applications requiring high integration and space savings. It features a small, surface-mountable form factor that is ideal for space-constrained applications. Additionally, the device supports “pin-strapped” output frequency programming to further reduce engineer bill-of-material (BOM) costs.

The 813N252CKI-02LF is an excellent choice for applications requiring a highly stable and reliable clock signal. It is commonly used in communications and datacenter equipment, server and storage systems, medical devices, and many other high-speed applications. It is a high-performance, yet cost-effective clock generator and frequency synthesizer solution.

The 813N252CKI-02LF works by generating, controlling, and distributing clock signals according to a reference frequency input. This reference frequency, or “parent” frequency, is provided to the device from an external source, such as a quartz crystal. The device identifies this frequency and uses it as a starting point to generate a new, customized clock frequency. It does this by using two main components: a programmable phase-locked loop (PLL) and a Voltage Controlled Oscillator (VCO).

The PLL functions to compare the frequency of an external reference signal with the output signal of the VCO. The PLL then adjusts the frequency of the VCO so that the output signal matches the external frequency, thus ensuring that the output signal is locked and accurately replicated. The PLL also minimizes signal noise and jitter, resulting in reliable, stable timing signals.

The VCO is the component of the 813N252CKI-02LF that produces the new clock signal. It does this by multiplying the reference signal by an adjustable numerical factor, producing a new clock signal of the desired frequency. This adjustment process is managed and controlled by the PLL, which ensures that the output signal remains locked to the reference frequency. The 813N252CKI-02LF also utilizes a on-chip divider to divide the VCO output signal by a factor of up to 32, thus further altering and fine-tuning the output frequency.

In conclusion, the 813N252CKI-02LF is a versatile and reliable clock generator and frequency synthesizer ideal for high-speed, high-precision applications. It is powered by a reliable PLL and VCO combination, and supports a wide range of adjustable frequencies, making it a tool of choice for many demanding communications and datacenter systems. It also supports power down and BOM-cost optimization features, thus making it a cost-effective and long-lasting solution for many digital applications.
