The 854S1208AYILFT is a versatile clock buffer, driver, and distributor that is mainly used to generated different clock signals for one clock input. This article will examine this device’s application field and working principle.

The 854S1208AYILFT is mainly used for clock management in digital systems. This includes distributing high-speed clock signals to all clock-active ICs, buffering low-speed clocks from a single source, fan-out multiple copies of a single clock, maintain jitter and noise reduction, and providing redundancy in time-critical applications. The versatility of this device is further enhanced by allowing users to select between two frequency multiplier options and various output enable functions that can be easily tailored to match their requirements.

In terms of its architecture, the 854S1208AYILFT is based on a low-skew phase-locked loop (PLL). It uses three distinct stages:  the multiplication, the PLL loop, and the output buffers. The multiplication stage amplifies either the clock input (1x multiplication) or the PLL output (2x multiplication) to achieve the desired output frequency. The PLL loop further refines this signal by filtering out noise and jitter, and then synchronizing it to a specific phase. Lastly, the output buffers use a low-capacitance architecture to help maintain the jitter reduction.

In addition to its architecture, the 854S1208AYILFT also supports a variety of peripherals. This includes several output enable options that allow users to control a subset of the clock outputs. It also includes several other options like spread-spectrum clocking for jitter attenuation and synchronized spread-spectrum for noise reduction. These options, in combination with the device’s already low-skew design, make it possible to achieve low jitter and high-reliability clock distribution.

In conclusion, the 854S1208AYILFT is a versatile clock buffer, driver, and distributor designed with a low-skew PLL architecture. It is primarily used for distributing clocks in digital systems, providing signal conditioning, and maintaining jitter and noise reduction. Lastly, it supports a variety of output enable options for more customization and includes peripherals like spread-spectrum clocking for jitter attenuation and noise reduction.
