Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers:

The 8T49N008A-999NLGI is a high-performance clock synthesizer and generator IC specially developed for standard communications systems. It is a low-power single-chip solution for generating ultra-low jitter clocks from frequencies of 0.1 MHz to thousands of MHz.

The 8T49N008A-999NLGI operates from a single 3.3 V supply, has analog and digital outputs, and is designed to facilitate easy interfacing and integration with various end-user applications. The clock synthesizer and generator is a highly integrated solution offering excellent performance and features such as an integrated pll, jitter attenuator, frequency retiming, and a fast frequency locking algorithm. The 8T49N008A-999NLGI is also programmable through a serial access line, allowing for customization of the operating parameters to the specific application.

Applications of the 8T49N008A-999NLGI are prolific and range from communications, networking, data storage, and broadcast markets to industrial and military applications. As a clock generator, it is ideal for systems requiring a phase-locked loop (PLL) with fast locking capabilities, low jitter, and high accuracy. As a clock synthesizer, it can be used for clock generation, clock distribution, and clocking of peripheral devices such as buffers, transceivers, and receivers. For instance, in an Ethernet switch, the 8T49N008A-999NLGI can provide a single frequency for synchronization between ports.

The working principle of the 8T49N008A-999NLGI is simple. It is first programmed by the user with the desired frequency. The frequency is then divided down to the required frequency and output. This clock is then monitored and, if needed, fine-tuned to the desired frequency. The clock is then sent to the various parts of the system, such as memory and processors, to be used as the main clock source.

The 8T49N008A-999NLGI features a wide range of performance features such as a jitter of less than 100 femtoseconds, fast locking time, and excellent jitter noise reduction. Additionally, it includes a wide selection of programming options such as multiple dividers, prescalers, and selectable spread-spectrum clocking. All of these features make the 8T49N008A-999NLGI an ideal choice for frequency synthesis and clock generation in a variety of applications.

In conclusion, the 8T49N008A-999NLGI is a high-performance clock synthesizer and generator IC specifically developed for standard communications systems. Its high-accuracy and low-power operation makes it perfect for a wide range of applications across different industries. Its intuitive design and easy-to-use features such as programmability, fast frequency locking algorithm, and excellent jitter noise reduction make it an ideal choice for clock generation, frequency synthesis, and distribution.
