Working Principle

The 8T49N222B-101NLGI core consists of digital, analog and integrated clock circuitry. The primary job of the digital and analog circuitry is to convert an external reference clock into predetermined, precise and adjustable output clock signals for different application uses. 8T49N222B-101NLGI is capable of producing and synthesizing two or four clock output signals from one input clock and providing high jitter attenuation.The integrated clock by 8T49N222B-101NLGI is capable of synthesizing different output frequency from the input reference. This means 8T49N222B-101NLGI can generate signals with different frequencies based on the input reference clock. It can be programmed to produce output signals whose frequencies are either identical or different than the reference clock.The phase locked loop (PLL) phase detector built into 8T49N222B-101NLGI allows it to generate precise clock signals. The built-in PLL technology makes it possible to detect phase errors between the incoming reference clock and the generated output clock. The PLL then forces the output clock to synchronize with the reference clock.8T49N222B-101NLGI includes programmable digital logic to adjust the circuitry connected to the integrated PLL. The 8T49N222B-101NLGI can be programmed to precisely adjust the output frequency and pulse width. This is one of the distinctive features of 8T49N222B-101NLGI that makes it suitable for many applications in different fields such as communication engineering, consumer electronics and medical equipment.Apart from the PLL, the 8T49N222B-101NLGI clock generates low jitter clock signals with an adjustable duty cycle. It can be programmed to generate accurate and stable clock signals with a duty cycle ranging from 50% to 99%. This makes it easy to adjust the output signals for specific applications.In conclusion, 8T49N222B-101NLGI is a highly efficient and versatile clock and timing chip that helps to generate and synthesize clock signals required for digital applications. It can be used in many sectors such as communication engineering, consumer electronics, medical equipment, military, aerospace and automotive industries. 8T49N222B-101NLGI is easy to use and offers a broad range of applications. With its integrated PLL and adjustable duty cycle, 8T49N222B-101NLGI can be used to generate precise and stable clock signals that are suitable for various applications.
