NB2309AI1DTR2G is a clock/timing product belonging to the clock generators, PLLs, and frequency synthesizers category. It is a small size, low power consumption, low noise, and high accuracy time/clock generator. It is suitable for a wide range of applications, such as digital video recording and playing, audio broadcasting, telecommunications, network system, satellite communication systems, and more.

The NB2309AI1DTR2G is a divide-by-N frequency synthesizer with a maximum resolution of 0.001Hz. The synthesizer consists of an analog phase detector, a loop filter, a voltage controlled oscillator (VCO) and a reference oscillator. By controlling the analog phase detector’s input and the reference oscillator’s frequency, the VCO can be made to stay locked to the reference oscillator and will follow any changes in the reference frequency without any additional control.

Ideally, the phase detector of a divide-by-N frequency synthesizer should be able to track phase difference, frequency difference, and phase noise. The NB2309AI1DTR2G’s phase detector has all the features of an ideal phase detector. It is also capable of synchronizing with an external clock signal, depending on the requirement.

The loop filter is a lowpass filter that is designed to reject the high-frequency jitter and phase noise while response quickly to changes in the reference frequency. The filter’s corner frequency is adjustable, allowing users to choose different corner frequency based on the specific application. The NB2309AI1DTR2G’s loop filter is able to achieve ±0.006Hz lock-in-range accuracy.

The VCO is the core of the NB2309AI1DTR2G. It is a highly stable frequency generator that produces accurate and pure sines waves which is essential in high-delay transmission applications. The VCO frequency range is 4µHZ - 200MHz and its frequency control range is 2µHZ - 100MHz. By dividing the VCO frequency, users can get finer resolution than 0.001Hz. In addition, the VCO also has a wide dynamic range (up to 40dB) and a low phase noise performance (−90 dBc/Hz at 1MHz offset), making it suitable for various applications like high-speed digital communication systems and base stations.

The reference oscillator of the NB2309AI1DTR2G is a highly temperature stable and low-noise oscillator that runs at 3.0V. It has a frequency range of 10 to 1,000 MHz and is versatile enough to be used in a wide range of applications. It is a good choice for timing reference and high-frequency clock generation.

In summary, the NB2309AI1DTR2G is a robust and reliable clock/timing module that provides precise and long-term production of accurate frequency clocks. With its wide temperature range, low noise level, adjustable loop filter, and external input synchronization, it is ideal for applications such as digital video recording and playing, audio broadcasting, telecommunications, network system, and satellite communication systems.
