Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 840004AG-01LFT device is an example of a clock or timing device used in a variety of applications. This device combines the functions of a clock generator (CG), phase-locked loop (PLL), and frequency synthesizer (FS) in a single, low-footprint package. As such, it is suitable for a range of design applications and can be used for both consumer and industrial purposes.

Application fields

The 840004AG-01LFT can be applied in both consumer and industrial applications. Consumer applications include digital televisions, Blu-Ray players, computer and game consoles, digital media players, GPS navigation systems, mobile phones and the like. The device is also capable of providing stable, precise timing signals necessary for industrial uses such as robotics, semiconductor manufacturing or testing equipment, medical imaging and control systems, and telecom systems.

Working principle

At the core of the 840004AG-01LFT is a PLL. The device uses a two-stage PLL architecture, consisting of a low-frequency clock generator followed by a frequency-synthesizer. By using a combination of PLL and frequency-synthesizer, this device is able to generate a wide range of output frequencies. The first stage of the PLL is the clock generator. This circuit generates an accurate, low-frequency clock signal that is used as a reference for the PLL. This clock signal is then used by the frequency-synthesizer to generate output clock signals with the desired frequencies. The PLL also incorporates a phase-locked loop, which enables the device to maintain precise frequency stability over wide temperature and voltage ranges. This feature prevents any jitter in the output signal and ensures a precise, stable performance. In addition to the clock generator/PLL/FS architecture, the 840004AG-01LFT also includes a USB port and an onboard temperature sensor. These features further add to the versatility of the device, as the USB port can be used to control the device directly, while the temperature sensor allows the device to adapt the output frequency to changes in the environment. Overall, the 840004AG-01LFT is an excellent choice for both consumer and industrial applications. Its combination of PLL, frequency synthesizer, and USB port make it a highly efficient and versatile device for a variety of applications. It is also a reliable and precise device, as it is capable of maintaining utmost accuracy over a wide temperature and voltage range.
