The NB3N51132DTR2G is a part of the clock generators, phase-locked loops (PLLs) and frequency synthesizers family. This product is a clock multiplication integrated circuit (IC) with features such as low jitter and high levels of integration, which provides users with the flexibility to configure a wide range of clock reference input frequencies with a selectable output clock range.

Application Field

The main applications for this product are networking, mobile and wireless products, computing, storage, smart grids, video broadcast and consumer audio, video applications. It is widely used for rate regeneration and fan-out, clock synthesis, crystal oscillator replacement, clock multiplier, frequency synthesizer and clock driver functions.

Working Principle

The NB3N51132DTR2G stores an internal frequency reference signal derived from a reference clock input. The internal reference signal is compared with an adjustable frequency signal derived from the crystal oscillator circuitry. The obtained data coming from the comparison is used to control the output divider. The output divider contains two sections, one for integer division and one for fractional division. This allows for finer control of the output frequency than traditional PLLs.

The product also contains four phase-frequency detectors (PFDs) which is used for clocking and phase comparison. This allows for a phase difference between the input and output frequencies which is equal to or less than 45 degrees. Additional features of this product consist of a power-down mode and two start-up options. The product contains a spread spectrum feature which can be used to reduce electromagnetic interference (EMI).

In addition, the NB3N51132DTR2G contains an integrated voltage-controlled oscillator (VCO) with low phase noise levels as well as reference input and reference output equivalents. The product also includes multiple frequency range settings, configurable lock time, and adjustable jitter filtering. This allows the user to customise and optimize the performance of the product based on their application needs.

The product is equipped with various features that make it suitable for a variety of timing and frequency applications. The NB3N51132DTR2G is designed to be compatible with voltage-controlled crystal oscillators (VCXO) and temperature-compensated crystal oscillators (TCXO) as well as being able to process very high frequency reference inputs. It also has high channel-to-channel skew, which allows the user to obtain better clock jitter performance.

In conclusion, the NB3N51132DTR2G clock generator and PLL frequency synthesizer product is suitable for a wide array of applications due to its high levels of integration and low jitter performance. It has multiple features that enable users to customise the product to their individual needs, as well as providing great performance, reliability and flexibility.
