CDCE421ARGER is a type of clock generator, frequency synthesizer, and phase-locked loop (PLL) device used for communication systems, industrial and military applications, and other electronics applications. It provides multiple outputs and can generate output frequencies up to and beyond 500 MHz. CDCE421ARGER is a fully integrated device designed to meet the most demanding clock requirements, offering excellent jitter performance, low power consumption, and high immunity to environmental noise. This article will discuss the application field and working principle of CDCE421ARGER.
Application Field
CDCE421ARGER is primarily used for communication and processing systems, including telecom and data processing applications, as well as for harsh environments or other electrical applications requiring precise clock frequencies. For example, CDCE421ARGER can be used in high-speed Ethernet switches and routers, optical transport systems, multiplexers, backplanes, load-balanced server platforms, and many other applications. Additionally, CDCE421ARGER is suitable for automotive, defense and aerospace, and medical applications due to its excellent jitter performance, low power consumption, and high immunity to environmental noise.
Working Principle
CDCE421ARGER works similarly to other clock generator, frequency synthesizer, and PLL devices. It gets an input signal, processes it, and generates several precise clock outputs. At the heart of the device is a configuration block responsible for setting a wide range of parameters, including input signal type and frequency, output type, frequency range, signal distribution, and other requirements. This block provides the flexibility needed to generate precise clock outputs for the application in question. Additionally, the output signals can be programmed to be both adjustable or fixed. An output amplifier is connected to the configuration block, which can adjust the signal level, impedance, and frequency response.
The signal is then split into various paths, each of which can be powered with a different voltage. The signal then passes through a hysteresis amplifier, which elevates the signal level before it is amplified and passed through a loop filter. The filtered signal is then fed back to the clock generator circuit, which looks for the input signal and adjusts the output samples accordingly. This effectively locks the output to the original input signal, reducing jitter and distortion in the output. Finally, the output signal is passed through an output buffer, which has the power to adjust the signal’s resistance, impedance, and level before it is sent to the output connectors.
CDCE421ARGER is an excellent example of a clock generator, frequency synthesizer, and PLL device that is designed to meet the most demanding clock requirements. It offers low power consumption, excellent jitter performance, and high immunity to environmental noise, making it suitable for applications in telecom and data processing, automotive, defense and aerospace, and medical applications.
