Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers - 5P49V5901B700NLGI8

Introduction

The 5P49V5901B700NLGI8 is a clock generator, phase-locked loop (PLL) and frequency synthesizer integrated circuit (IC). It is a low-power, high-performance, low-jitter clock generator designed to be used in data channel clock generation applications, such as hard drives, optical drives, digital cameras, and cell phones. It allows for both simple and complex timing requirements in a wide range of commercial, industrial and consumer products.

Application Field

The 5P49V5901B700NLGI8 is targeted for applications requiring cost-efficient and low-power clock generation solutions. Its applications include:• High-speed clocking and data rate detection. • Digital communication system. • Process control systems. • Store and forward switching system. • Time division multiple access (TDMA). • Frequency synthesizers in HF and VHF radios. • Frequency hopping radio system. • Room-temperature radio system. • High-speed buffering and re-timing application.

Working Principle

The working principle of the 5P49V5901B700NLGI8 is based on a phase-locked loop (PLL) circuit. The basic principle of PLL circuit is to compare the input frequency with an oscillator frequency and generate an error signal which is used to control the frequency of the oscillator. The error signal generated can be used to lock the oscillator to input frequency. The power supply for the 5P49V5901B700NLGI8 is 1.8 volts. This IC supports two modes of operation: the first one is the static mode, where the frequencysynthesis is locked to an external reference clock of up to 40MHz, and the second one is the dynamic mode, where several channels can be hyperlinked, allowing for agile frequency synthesis. In addition to this, the device supports four independent digital-to-analog converters (DACs) with adjustable gainand offset settings for clock frequency fine-tuning, enabling it to generate clocks with ultra-low jitter performance up to 300MHz, with typical jitter below 200 femtoseconds.

Advantages

The primary advantages of the 5P49V5901B700NLGI8 include:• Low power consumption. • Cost-efficiency. • High performance and low jitterclock generation. • Ultra low jitter performance up to 300MHz. • Supports two modes of operation (static and dynamic). • Supports four independent digital-to-analog converters. • Adjustable gain and offset settings for clock frequency fine-tuning.

Conclusion

The 5P49V5901B700NLGI8 is an integrated clock generation IC which is targeted for low-power and cost-efficient applications. Its high performance and low-jitter clock generation capabilities make it suitable for applications requiring ultra low jitter performance up to 300MHz. The device also supports two modes of operation (static and dynamic) and four independent digital-to-analog converters with adjustable gain and offset settings for clock frequency fine-tuning.
