Clock and timing devices are required in almost every electronic system, from low power mobile devices to high speed telecom systems. One of the most important devices in this area is the 5P83908NDGK clock buffer, driver, or repeater, which is a key component in providing synchronization between clock domains. This article will discuss the application field and working principle of the 5P83908NDGK.

The 5P83908NDGK is a low power, ultra-low jitter, 8-clock buffer. It is specifically designed for clock and timing applications in high-speed telecommunications, backplane, and high-end computing systems. The device has an operating temperature range of -40°C to +85°C and is designed to operate within a power supply range of 2.3V to 3.3V. It is build with an integrated PLL with two outputs that support two clock domains. The 8-clock buffer has two outputs with 2ns of total delay, whereas the PLL has a 500ps phase jitter at 182MHz.

The 5P83908NDGK is used for buffering the clock signal throughout the system. It is designed to accept either a low-swing LVPECL or a high-swing LVDS differential clock signal. The output of the 5P83908NDGK is generated by a digital clock synthesizer that uses a combination of Phase-Locked-Loop (PLL) and a multiplication factor to generate a clock signal with different frequency and duty cycle. The output can be configured to be low-swing LVPECL or high-swing LVDS. In addition, the output signal has an adjustable skew between 0 to 2ns and can be phase shifted using an external resistor.

The 5P83908NDGK is also used for clock distribution throughout the system. The device has four outputs that can be used to provide clocking signals of different frequencies and duty cycles to different parts of the system. The output of the 5P83908NDGK is generated by the built-in PLL and the multiplication factor, which can be programmed to generate different output frequencies and duty cycles. Additionally, the 5P83908NDGK can be used to provide clock signal synchronization between different clock domains. This helps reduce jitter and improve signal integrity between different clock domains.

In addition to providing clock signal synchronization and distribution, the 5P83908NDGK can also be used for clock and data recovery in high speed systems. The device has an integrated digital phase-locked loop (DPLL) which can generate an output signal with a desired frequency and duty cycle from an incoming data stream. This can be used to improve signal integrity by reducing the jitter in high speed systems.

To sum up, the 5P83908NDGK is a low-power, ultra-low jitter 8-clock buffer with integrated PLL. It is designed for high speed communications, backplane, and computing systems. The device can be used for buffering clock signal, distributing clock signal to different parts of the system, and recovering clock and data in high-speed systems. Finally, the integrated DPLL and multiplication factor allows the output signal to have an adjustable frequency, duty cycle, and skew.
