Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 8T49N283C-999NLGI is a frequency synthesizer from IDT (Integrated Device Technology). This frequency synthesizer is specifically designed for applications requiring the generation, multiplication and division of frequencies. These frequencies can be used for applications in telecommunications, networking, video, aerospace and military sectors. With a wide PLL bandwidth with programmable step sizes, the 8T49N283C-999NLGI is perfect for use in the most demanding of applications.

The 8T49N283C-999NLGI works by taking in a reference signal from an external clock source. This external clock can be from an oscillator or other 10 Mhz clock generator. This external clock has a frequency of 10 Mhz and is used by the 8T49N283C-999NLGI frequency synthesizer to generate multiple frequencies. The 8T49N283C-999NLGI can generate frequencies from 10 Mhz to 4.8 Ghz. This range is selectable depending on the application. The frequency of the generated signal is calculated by the 8T49N283C-999NLGI’s internal programmable divider and phase-locked loop (PLL).

The 8T49N283C-999NLGI is programmed using integrated registers. These allow the system to be configured and tuned according to the user’s requirements. The registers are programmed with values corresponding to the desired output frequency. The 8T49N283C-999NLGI has an integrated DC-DC converter which can be used to supply power to the external clock source if required. The 8T49N283C-999NLGI also has an integrated reference bypass capacitor which eliminates the need for an external clock source in some applications.

The 8T49N283C-999NLGI features a PLL bandwidth of 620 MHz, a fractional-N modulator with 45 big steps, and a third-order delta-sigma modulator. This allows the 8T49N283C-999NLGI to create precise signal frequencies with minimal jitter or phase noise. The 8T49N283C-999NLGI is also capable of generating a wide range of output signal formats such as LVDS, LVPECL, SSTL and HCSL. It supports signal generation of multiple frequencies in a single frequency synthesis operation.

In summary, the 8T49N283C-999NLGI is a frequency synthesizer that is specifically designed for applications requiring the generation, multiplication and division of frequencies. It is capable of creating precise signal frequencies with minimal jitter or phase noise, and supports signal generation of multiple frequencies in a single frequency synthesis operation. It is ideal for use in applications in telecommunications, networking, video, aerospace and military sectors.
