The 9FGV1001B004NBGI is a mixed signal clock generator with PLL technology and is used for a variety of applications in the field of clock/timing. As a clock generator, it can generate various clock signals with various clock frequencies, while its PLL technology ensures low phase noise and excellent frequency stability. This makes the 9FGV1001B004NBGI suitable for application fields such as communication systems, storage systems, and computing systems.

The 9FGV1001B004NBGI consists of several parts including a phase-locked loop (PLL), a crystal oscillator, several digital logic circuits, and other associated circuits. The PLL converts an external reference frequency into a higher frequency by multiplying it with a certain factor called the multiplication factor. This multiplied frequency is then used to drive an internal high-precision crystal oscillator, providing high accuracy and frequency stability.

The 9FGV1001B004NBGI also features an external spread-spectrum oscillator (SSO) for reduction of system-level EMI emissions. The spread spectrum oscillator generates a wide range of frequencies which are cyclically shifted away from the main frequency and with small amplitude, in order to reduce EMI emissions in the system. This feature allows the 9FGV1001B004NBGI to fulfill the requirements for EMI compliance in some application fields.

The 9FGV1001B004NBGI has a number of digital logic circuits such as phase-fired logic circuits and low-skew delay-locked loop circuits. These circuits can be used to generate various internal and external clock signals. These signals can be further manipulated by the device to generate two high-frequency square wave outputs and two DDR (Differential Data Rate) outputs which can be used to obtain signals of various levels and schemes.

The 9FGV1001B004NBGI is a versatile clock generator and has many applications in the clock/timing field. It can be used as a clock source for communication systems, storage systems, and computing systems, providing versatile and reliable solutions for these application fields. Additionally, with its low phase noise and EMI compliance features, it is ideal for designs which need to meet stringent EMI and performance requirements.
