Introduction

8T49N241NLGI is a programmable clock generator, phase-locked loop (PLL), frequency synthesizer, and jitter cleaner from IDT. It combines programmable functionality, jitter attenuation, and flexible output drivers in a TSSOP-20 package. This innovative product integrates a selectable PLL or frequency synthesizer, programmable clock sources, input/output buffers and jitter filters into one device.

Application and Working Principle

The 8T49N241NLGI can be used for a variety of applications, from general-purpose synchronous clock generation to timing solutions for the most advanced communication systems. Its wide range of input frequencies, high output frequency resolution, low output jitter and low power consumption make it an ideal clock solution for many devices, such as digital signal processors (DSPs), digital-to-analog and analog-to-digital converters (DACs/ADCs), and media players.The device works by generating a programmable reference frequency from an external clock source. This reference frequency is then multiplied or divided by a programmable divisor to generate a desired output frequency. The output is further filtered by an input buffer and a jitter attenuator. The jitter attenuator is designed to reduce the high-frequency jitter that can occur at the device\'s output, thereby improving system performance.

Conclusion

The 8T49N241NLGI from IDT is an ideal clock solution for many devices, including digital signal processors, DACs/ADCs, and media players. It provides a wide range of input frequencies, high output frequency resolution, low output jitter and low power consumption. The device works by generating a programmable reference frequency from an external clock source and then multiplying or dividing it by a programmable divisor. It also includes an input buffer and a jitter attenuator, designed to reduce high-frequency jitter at its output, resulting in improved system performance.
