The 8T49N203A-015NLGI clock generator is a PLL based clock generator designed for ultra-low-jitter clock synthesis applications. It is targeted for applications such as clock and data recovery, base station timing, digital TV and digital radio broadcast, routers, network switches and general-purpose communications systems. The 8T49N203A-015NLGI is highly integrated with a programmable Voltage Controlled Oscillator (VCO) and Synthesizer circuit, with on-chip fractional-N synthesis technology.

This clock generator is based on a dual-mode PLL architecture that includes a reference oscillator, an analog loop filter, and a digitally-controlled VCO. The reference oscillator, made up of an external crystal or reference clock source, drives the feedback of the PLL and sets the loop bandwidth and jitter performance. The analog loop filter provides stable loop characteristics and is optimized for high-speed clock and data recovery applications. The digitally-controlled VCO is the output stage of the PLL and is adjustable over a wide range of frequencies.

The 8T49N203A-015NLGI clock generator is capable of synthesizing frequencies up to 600 MHz with a wide range of operating voltages and temperatures, making it very adaptable to a multitude of applications. It is also very low power, consuming as little as 6mW. In addition, it is able to achieve very high performance specifications, with frequency synthesizers having jitter performance of less than 50ps RMS over a wide frequency range. This makes it ideal for applications that require high-speed performance, low power consumption, and excellent jitter characteristics.

The 8T49N203A-015NLGI also features a wide range of features, including a deep on-chip memory and integrated phase-locked loop (PLL) support. The deep on-chip memory allows the user to store a wide range of frequency settings and allows for customizing the output frequency in different operating environments. The integrated PLL support allows the user to program various frequency settings, such as output frequency offset, VCO gain adjustment, duty-cycle adjustment, and spread spectrum adjustment. The 8T49N203A-015NLGI clock generator also features an integrated low-jitter reference divider, which improves the jitter performance of the device.

The 8T49N203A-015NLGI is a highly versatile clock generator, allowing for numerous frequencies and applications. It offers excellent performance in terms of jitter, power consumption, and wide range of operating temperatures and voltage levels. Its deep on-chip memory and integrated phase-locked loop support provide users with a wealth of frequency settings and customizations, making it perfect for high-speed clock recovery applications.
