100EL16M Application Field and Working Principle

100EL16M is a high performance, low power enhanced phase-locked loops (PLL) designed for data communication systems such as Gigabit Ethernet. It is able to generate a clock (REFCLK) at a speed of up to 6.25GHz with a low jitter of less than 1ps, providing excellent accuracy and repeatability. Its voltage controlled oscillator (VCO) has a frequency range of up to 2.5GHz with a resolution of 0.2Hz and a wideband range of up to 2.5GHz.

In addition, 100EL16M features a jitter attenuator, which allows it to reduce noise and jitter on the clock, ensuring reliable and consistent clock signals. This can be used in a variety of applications, such as optical transceivers, Ethernet routers, and wireless adapters.

Applications

100EL16M can be used in a variety of applications, from communication systems such as Gigabit Ethernet, to frequency synthesizers and clock generators. With its high speed and low jitter, it is well suited for these applications and can be used in many different environments.

Additionally, 100EL16M can be used in many types of data communication systems, such as in high-speed serial links and multiplexers, or as a clock source for many digital signal processors and high-speed ADCs and DACs for precision timing.

Working Principle

100EL16M is based on a phase-locked loop (PLL) architecture. A PLL is a type of closed-loop feedback system used to synchronize signals between two or more parts of a communication system. The PLL is designed to distinguish between the frequency of a reference clock and the actual frequency of the clock signal and then adjusts the output frequency to match the reference frequency.

The 100EL16M includes two parts: an oscillator and a phase-frequency detector. The oscillator is responsible for producing the clock signal (REFCLK) at a desired frequency, while the phase-frequency detector compares the phase and frequency of the reference clock and the clock signal. If there is a difference between the two signals, the PLL will adjust the output frequency to match that of the reference.

The 100EL16M also features a jitter attenuator, which reduces noise and jitter on the clock signal, ensuring reliable and consistent clock signals. This can be used in a variety of applications, such as optical transceivers, Ethernet routers, and wireless adapters.

Conclusion

100EL16M is an enhanced phase-locked loop designed for data communication systems, such as Gigabit Ethernet. It can generate up to 6.25GHz clock with a low jitter of less than 1ps, providing excellent performance. In addition, its wideband range and jitter attenuator enable it to be used in a variety of applications.
