NB2305AI1DG is a clock generator, PLL, frequency synthesizer typically used as a silicon-timing device. It operates in both a Single Clock (SCK) and Dual Clock (DCK) mode, allowing a wide variety of commonly used clock frequencies to be generated. The NB2305AI1DG has no setup requirements and can be used with a wide variety of applications, ranging from industrial systems and servers to consumer electronics.

Application Field

The NB2305AI1DG is an advanced, low jitter clock generator that offers an ideal solution for cost-sensitive high-speed application such as communication systems, servers, clocks and oscillators. With clock frequency range from 40-400MHz, the NB2305AI1DG provides superior jitter performance for applications in industries such as aerospace, automotive, medical, and telecommunications. The NB2305AI1DG is ideal for applications such as packet and protocol transmitted over Ethernet, Wi-Fi, fiber, and backplane connections.

Working Principle

The NB2305AI1DG uses a phase-locked loop (PLL) to generate its clock frequencies. The PLL consists of a reference crystal oscillator and a phase-frequency detector, which samples the oscillator\'s output and compares it to a reference clock input. The output of the PLL is locked to the reference clock at a frequency determined by the divider values. The reference clock input can range from 32.768kHz to 2.2GHz, depending on the configuration.

The NB2305AI1DG uses a low current operation, meaning it consumes only a minimal amount of power. When operating in single clock (SCK) mode, only one crystal oscillator is used, which simplifies system design and reduces component count. The device is also capable of operating in dual clock (DCK) mode, in which two crystal oscillators are used, both operating at different frequencies.

The NB2305AI1DG is optimized to provide superior jitter performance and is available with a variety of output frequencies. It includes an internal loop filter that helps minimize jitter and noise, ensuring the device meets stringent jitter requirements. It is also equipped with frequency-lock features that enable frequencies to remain precisely in lock.

The NB2305AI1DG can be used for a variety of applications, including automotive systems, mobile radios, industrial control systems, and wireless communications. It is available in a 64-pin LQFP (Leadless Quad Flat Power) package that is ideal for high density applications. The NB2305AI1DG is an ideal solution for anyone looking for a cost-effective, high-performance clock generator.
