Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 8T49N008A-004NLGI8 is a programmable clock generator used in applications such as microprocessors, FPGAs and ASICs, offering precise frequencies from 2 Hz to 150 MHz. It offers jitter works of 300 fs and frequency stability of ±50 ppm over a temperature range of -40°C to +85°C. It can source up to four outputs simultaneously and is fully programmable via a serial bus. The 8T49N008A-004NLGI8 can be used in a variety of applications, as a jitter attenuator, timing source, and frequency multiplier. The 8T49N008A-004NLGI8\'s primary function is to generate precise and stable frequency outputs with low jitter. It offers a single reference clock, up to four highly accurate outputs, and frequency synthesis capabilities. The 8T49N008A-004NLGI8 features frequency modulation using a pair of selectable PLLs for precision frequency tuning in applications requiring frequent corrections such as communications systems. The 8T49N008A-004NLGI8 works by receiving a reference input clock signal and applying it to a phase-locked loop (PLL). The PLL generates an internal clock signal that can be divided down or multiplied up to generate desired output signals. Each PLL has two input muxes, two output dividers, a phase detector, and a filter. These components work together to generate a stable output signal with a precise frequency, low phase noise, and low jitter. The 8T49N008A-004NLGI8 also includes a digital trimming control to precisely adjust the output frequency to the desired target. By controlling the frequency of the output signals, any frequency range can be generated. The output clock signals are low-skew and glitch-free due to the integrated digital glitch filter and the highly accurate output divider. The 8T49N008A-004NLGI8 can be used for applications such as communications systems, telecommunications and datacom, audio and video systems, test and measurement, military and aerospace, optical communication, and general phase-locked loop solutions. It can be used as a clock source, jitter attenuator, frequency synthesizer, and divider, and can be used to generate any desired frequency range. The 8T49N008A-004NLGI8 is manufactured with the latest process technology and includes application specific parameters to optimize the clock generator for specific applications. This clock generator’s small size, low power consumption, and high performance make it an ideal choice for many clock and timing solutions.
