The NB2309AI1HD is an advanced pair of fully integrated clock / timing generator systems designed to meet a wide range of applications. With ultra-low jitter divided clocks and a variety of frequencies up to 300 MHz, the NB2309AI1HD can be adapted to a variety of sources such as crystal oscillators, voltage controlled oscillators, or pre-made or factory programmed devices.It provides a wide range of features, including their low-jitter, high-frequency outputs, a wide frequency range (up to 300 MHz), a low-power reset output, synchronization via change of state register, operation in either a synchronous or asynchronous manner, and a single-wire data strobe for easy programming. Additionally, the NB2309AI1HD is capable of producing multiple high-frequency outputs with very low jitter, which can be used for data communications, clock distribution, and other applications requiring multiple clock domains. The NB2309AI1HD has two major components, an oscillator block and a PLL block. The oscillator block consists of two main components, a main oscillator section that feeds an EXTCLK pin which provides an external system clock, and a low-jitter clock generator that produces a very low-jitter output clock. The low-jitter clock generator takes the input system clock and performs several Operations such as a Phase-Locked Loop (PLL), Frequency Divider (FD), Pulse Width Modulator (PWM), and clock generator. Together, these operations provide a very low-jitter clock output with almost any desired frequency up to 300 MHz. The PLL block consists of two main components, a loop filter and a phase/frequency detector. The loop filter is used to determine the loop bandwidth for the phase/frequency detector. The phase/frequency detector is used to compare the phase and frequency of the input system clock with that of the main oscillator block clock. If the phase/frequency detector detects an error, it will adjust the PLL loop gain as necessary to bring the phase and frequency back in sync. Once the phase and frequency have been adjusted by the phase/frequency detector, the loop filter then acts as a low pass filter to reduce the high-frequency output jitter. The result is a very low-jitter output clock that can be used in a wide range of applications. The NB2309AI1HD is ideal for applications such as high-speed data transfer, clock synchronization, clock distribution, and more. It can also be used in a variety of communications applications such as cellular networks, Ethernet, and Fibre Channel links. The NB2309AI1HD is also suitable for use in a wide range of applications that require low-jitter, high-frequency outputs, such as in computing, audio, and video systems. The clock output can also be used in a variety of other applications, including clock generation for FPGA, PLD, and ASIC devices. In conclusion, the NB2309AI1HD is a highly advanced pair of integrated clock / timing generator systems that is capable of providing low-jitter, high-frequency outputs up to 300 MHz. The integrated PLL and frequency divider allow for almost any frequency to be generated with extremely low jitter. This makes the NB2309AI1HD an ideal solution for applications requiring multiple high-frequency outputs with low-jitter.
