Clock generator ICs have long been used to provide accurate timing and clock signals to a wide variety of applications. 844256DGILF is one of these ICs that is used as a Frequency Synthesizer, a device to generate clock signals with a frequency synthesized from a reference frequency. It is a dual-frequency synthesizer, meaning that two different frequencies can be output. The 844256DGILF is suitable for use in many types of clock applications such as television, video, digital audio and mobile communications. This article will discuss the application field and working principle of the 844256DGILF.

The 844256DGILF is a dual frequency synthesizer IC which generates two frequency signals based on a reference clock. The frequency of the output signals can be programmed as long as they are within a predetermined range. The device is capable of producing a wide range of frequencies from 2MHz to 400MHz and is therefore suitable for a wide range of applications such as television, video, digital audio and mobile communication. The output signals have a very low jitter and very low spurious levels, ensuring the accuracy of the generated signals.

The working principle of the 844256DGILF is based on the use of Phase Locked Loops (PLLs). PLLs are a circuit which uses the input reference clock to generate a signal of a specific frequency. The 844256DGILF uses two PLLs in order to generate the two different output frequencies. The output signals of the two PLLs are combined to form the desired frequency outputs. The two PLLs are programmed in such a way that the desired output frequencies can be produced without any distortion.

The 844256DGILF is a highly versatile device and is suitable for a wide range of applications. It can be used in television, video and digital audio applications where accurate and reliable clock signals are required. It is also used in mobile communication systems where accurate timing signals are essential. The device is known for its high accuracy, low jitter and low spurious levels.

In conclusion, the 844256DGILF is a dual frequency synthesizer IC designed for applications where accurate and reliable clock signals are required. It uses two Phase Locked Loops (PLLs) to generate the two different output frequencies. The device is suitable for a wide range of applications, including television, video, digital audio and mobile communication. The output signals have a very low jitter and very low spurious levels, ensuring the accuracy of the generated signals.
