The NB3N508SDTR2G is a highly-integrated clock multiplier, frequency synthesizer and PLL device that provides a versatile frequency generation and clock management solution. The NB3N508SDTR2G which is the latest member of ON Semiconductor’s NB3N clock family, is a highly-scalable frequency synthesizer that supports MHz to low GHz frequency range. This device has the ability to generate a variety of output formats, including single- or dual-data rate (DDR/DDR2/DDR3) High-Speed Serial (HSS) clocks and spread-spectrum clocking (SSC) signals.

The NB3N508SDTR2G is designed to generate and manage the clock distribution across a wide range of system parameters, including power, temperature and process variation. Its enterprise-class clock synthesis is based on the innovative frequency generation technology that allows high-speed, jitter-immune clock output with precision frequency control, low input jitter and excellent spectral purity.

The NB3N508SDTR2G is an ideal clock generator for any application that needs precise control of frequency, phase and jitter. It can be used in high-performance systems including telecommunications, networking, and base station infrastructure. Additionally, it is suitable for applications such as high-end computing and storage, medical instrumentation, robotics, and machine learning applications.

The working principle of the NB3N508SDTR2G is based on a phased-locked loops (PLL) with fractional-N frequency synthesis technology. A PLL is an electronic circuit which uses the feedback technique to generate an output signal with a shifted phase and frequency relative to its input signal. Fractional-N frequency synthesis acts as an advanced digital frequency synthesizer that utilizes a fractional-N ratio to produce a more uniform frequency compared to an integer-N ratio. With this device, the user can decide either to use a fractional-N or integer-N ratio depending on the scenario.

The NB3N508SDTR2G utilizes a patented reference signal synthesizer with improved jitter rejection for enhanced spectral purity. This signal can be used for both the system reference input or for initiating calibration mode. The device has an integrated non-volatile memory that stores the user configuration settings. It uses a three-step calibration routine for optimizing the reference input and output signal frequencies, along with integrated loop filters for controlling the jitter and producing a high-quality Synthetic Clock (SynClk) with low noise and jitter.

The NB3N508SDTR2G is a versatile frequency synthesizer that supports a wide range of frequency synthesis para-meters and allows the user to tailor the frequency, phase and jitter performance to the exact requirements of the innovative application. It has a wide range of output frequency and levels, allowing it to be used for a variety of clock generation applications.
