AK8172A is a family of clock generators, phase-locked loops (PLLs) and frequency synthesizers providing ultra-low jitter clock signals for the development of high-precision systems. The AK8172A is designed for the world\'s highest jitter performance of 0.65ps in octal PLLs, giving it the capability to generate and synthesize frequencies with great precision and accuracy.

The AK8172A utilizes a combination of advanced Phase-Locked Loop (PLL) and Voltage Controlled Oscillator (VCO) techniques to generate and synthesize low-jitter outputs from a reference clock or an incoming clock signal. The device includes a wide range of features and options, such as an integrated crystal oscillator, an external reference clock input, and an External Run Input function that allows the device to operate as a slave to an external clock source.

The device offers two operating modes: an open-loop, which provides frequency synthesis with no selectable reference frequency, and a closed-loop, which utilizes an externally supplied referenceclock signal, allowing the AK8172A to generate low-jitteroutputs of a specified frequency, as determined by the reference signal. In either mode, the device can generate a wide frequency range: from 4MHz to 5GHz using an internal oscillator, and up to 25GHz using an external clock source.

The AK8172A provides software-selectable output frequencies for over 60 different frequency bands, ranging from 128 to 25,600MHz, making it suitable for a wide range of applications, such as FPGAs, communications processors, routers, and embedded systems. Additionally, the integrated Phase-Locked Loop (PLL) supports low-phase noise PLL configurations, enabling the device to provide a low-jitter output signal of desired frequency.

The AK8172A is designed for applications requiring low-phase noise and low jitter performance. The device is ideal for use in critical low-noise environments, such as telecommunications, test and measurement, and industrial automation. The device\'s wide frequency range and integrated Phase-Locked Loop (PLL) make it suitable for applications requiring both high-frequency clock signals for data processing and fast analog clocks for radio and digital transmission.

The AK8172A is a low-power, cost-effective device, providing a wide frequency range and low jitter performance. Its integrated Phase-Locked Loop (PLL) allows the device to generate a low-jitter output signal with a desired frequency. Its wide frequency range and support for a wide range of output frequencies make it suitable for a huge variety of clock and timing applications.
