Clock/Timing - Clock Buffers, Drivers is a type of integrated circuit devices that offer low-skew and low-jitter solutions for splittinng, distributing and multiplying clock signals from a single common source. Among them, 8516FYT is a kind of low jitter clock buffer, which provides a suitable solution for the applications where high clock integrity are required. The following is about 8516FYT application field and its working principle.

8516FYT encompasses multiple features, such as 6 differential or 12 single-ended outputs and supports fanout of 2 to 5 LVPECL, 2 to 5 LVDS, 2 to 9 LVHSTL or 2 to 9 SSTL_2 outputs. It can reach 4x to 8x higher fanout than other similar products. The device also provides excellent electrostatic discharge (ESD) protection, an ultra-low jitter, low additive jitter and low periodic jitter which make 8516FYT an ideal device for high-end networking and server applications.

Besides, 8516FYT is also very suitable for telecommunication, test and measurement, instrumentation and imaging, broadcast video, video security, multimedia, audio and other clock-driven applications. This feature makes it possible that 8516FYT can be integrated into a wide range of system designs. In addition, the device is general purpose and could operate with low-skew and low jitter in the range of -40°C to 125°C temperature operation.

The working principle of 8516FYT is quite simple and clear. Firstly, integrated circuits inside 8516FYT perform level/impedance conversion and buffering. A high-frequency or low-jitter oscillator usually operates at a much higher frequency than core logic. Then, input signals go through the integrated circuits, on-chip level conversion or impedance conversion which receives functional signals. The functional signal then is transferred to the integrated output buffers, where flexible output download protocols, such as 8B/10B encoding and all high-partition codings, can be chosen, based on the specific application needs. Finally, the signal reaches high-speed outputs and is transferred to core logic.

The 8516FYT utilizes differential output buffers and chips achieve low-jitter outputs, lower than 10ps RMS, by using phase-locked-loop (PLL) technology, which consists of an active loop filter for inductor-less low-pass filters and a switch-capacitor based loop filter. 8516FYT also utilizes many other features to ensure the low jitter, such as differential clock inputs, low power consumption, extended temperature ranges, output terminated and many others.

In conclusion, the 8516FYT is a very versatile and multifunctional clock buffer solution, offering a range of features that suit a variety of application, such as telecommunication, test and measurement, instrumentation and imaging, broadcast video, video security, multimedia, audio and other clock-driven applications. It also has a very simple and clear working principle, and output protocols and integrated circuits are able to provide a low-jitter and low-skew clock signals. Therefore, it is a very ideal choice for high-end networking and server applications.
