8735AY-31LFT

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers - encompass a wide variety of components with a range of specific applications. 8735AY-31LFT, in particular, is a frequency synthesizer module from IDT that offers fast switching speeds, and a wide range of frequencies over many wideband process phases, making it highly suitable for radio communications and high-end audio applications.

At the heart of the 8735AY-31LFT is a Phase Locked Loop (PLL) circuit, which functions by dividing an incoming signal into two, relatively equal frequency signals. One side is inputted into a Phase Detector, the other and is divided in two further sections, one for further division and one for comparison by the Phase Detector. The PLL will adjust the frequency of the incoming signal to keep the two sections, from the reference input, exactly in sync.

In the 8735AY-31LFT, the reference input can be provided from either an external reference clock, or from a built-in low-noise master oscillator, making it ideal for oscillator and PLL systems. The output of the PLL is then used as the reference for a VCO (Voltage Controlled Oscillator) to further divide or multiply the frequency generated, allowing for the generation of many wideband process phases.

The 8735AY-31LFT frequency synthesizer module takes advantage of an ultra-small form factor and 72-lead LQFP package to offer features that are typically found in much larger components. This makes it ideal for high-speed applications in a wide range of fields including wireless communications, automotive applications, consumer electronics, military/aerospace and industrial applications.

The 8735AY-31LFT\'s fast switching speeds, wide frequency range and high-accuracy outputs make it suitable for many devices requiring multiple phase outputs. The module offers an adjustable Reference Frequency range from 110MHz-80GHz with an output range from 1.4GHz-4GHz, and phase noise anywhere from -123dBc/Hz to -127dBc/Hz for a -1dBc de-skew at 1GHz.

Finally, the 8735AY-31LFT also provides robust protection from Electromagnetic Interference (EMI) by incorporating several different measures. These include shielding in both the digital and analog sections of the module, as well as special ground plane shields preventing interference from external components.

The 8735AY-31LFT frequency synthesizer module is perfect for those needing the capabilities of a high-end PLL or oscillator system without having to sacrifice size or complexity. Its wide frequency range and fast switching speeds make it well-suited for radio communications and high-end audio applications as well as for a range of other applications where multiple phase outputs are required.
