The NB2308AI4DTG is a 4-channel differential clock generator designed by Corning Cable Systems. It is specifically designed to generate and distribute up to four different frequencies or clock signal outputs. It is most commonly used in applications that require accurate timing or clock signal synchronization such as timing processors and related systems in FPGAs, microcontrollers, or digital signal processing (DSP) applications. The NB2308AI4DTG can also be used in a variety of other applications such as providing clock signal synchronization in telecom and networking systems.

The NB2308AI4DTG is a frequency synthesizer, specifically a phase-locked loop (PLL) based, clock generator. A PLL is a closed-loop system that synchronizes the phase and frequency of an input signal to a reference signal called a reference frequency. The NB2308AI4DTG uses an external reference frequency to lock its output signal to the reference signal. The data rate, signaling format, operating frequency, and pattern all depend on the reference signal.

The NB2308AI4DTG incorporates a low-jitter PLL clock synthesizer, which helps reduce input jitter and improve system performance. Its PLL consists of a phase comparator, a low-pass filter, and voltage controlled oscillator (VCO). The PLL continually adjusts the VCO frequency so that it is in phase with the input reference signal. The average differential output of the NB2308AI4DTG ranges from 125 MHz to 333 MHz and is ideal for FPGA, Microcontroller and DSP applications. Its internal clock multiplier divides down the reference frequency to achieve higher data rates, making it the perfect choice for telecom applications.

The NB2308AI4DTG offers 4 differential clock outputs that can be used to generate multiple frequencies and signaling formats. It also includes an LVTTL input and output that can be used for switching clocks, as well as a strobe output that can be used for testing purposes. Additionally, the device\'s flexible PLL SynClock™ architecture allows the user to automatically regulate its output frequency. This feature is especially useful when dealing with frequency drift due to environmental or temperature variations.

The NB2308AI4DTG offers exceptional performance, making it the ideal solution for telecom and networking applications. Its low jitter PLL ensures clean, accurate clock signals, giving users improved system performance and accuracy. Its low power consumption and low EMI/RFI emission makes it suitable for a wide range of applications. It also has integrated skew management and power saving modes to further reduce power consumption. Last but not least, the device is qualified to Telcordia GR-1221-Core requirements.

In sum, the NB2308AI4DTG is a 4-channel differential frequency synthesizer/clock generator designed by Corning Cable Systems. It is most commonly used in applications that require accurate timing or clock signal synchronization such as FPGA, microcontroller and DSP applications. Its PLL consists of a phase comparator, a low-pass filter and voltage controlled oscillator. The average differential output range of the NB2308AI4DTG ranges from 125 MHz to 333 MHz, making it the perfect choice for telecom applications. Its low jitter PLL ensures clean and accurate clock signals, low power consumption and low EMI/RFI emission. Its flexible SynClock™ architecture allows the user to automatically regulate its output frequency. Additionally, the device also has integrated skew management and power saving modes to further reduce power consumption. All of these features make the NB2308AI4DTG an ideal solution for telecom and networking applications.
