CY2547FC is an ultra-low phase noise clock generator that meets the most stringent phase noise requirements for the highest performance cloud-based applications. This unit operates from an internal oscillator running at an 800MHz frequency, and provides low-amplitude clock outputs of up to 100MHz. It also offers a wide range of features, such as pre-programmed outputs, a dynamically adjustable output frequency, and 3rd-order jitter suppression. This device provides both highly repeatable and highly accurate performance, making it suitable for cloud computing, datacenters, and other high-performance computing applications.

The CY2547FC clock generator takes a synchronous, 800MHz clock and produces one or more low-jitter clock outputs. It has eight synthesized outputs, and the user can pre-program the desired output frequencies. The output frequency range is between 100 Hz and 100 MHz, with an accuracy of 0.01%. The device uses an onboard programmable PLL and an analog loop filter to maintain synchronization between the output frequencies and to provide a low-amplitude jitter. The cycle-to-cycle jitter on the output is typically less than 1ps. In addition, the device can be configured to automatically maintain a lock on the input clock in the event that the frequency drifts.

The CY2547FC clock generator can be programmed for operation in either frequency-modulated (FM) or phase-locked loop (PLL) mode. In FM mode, the output frequency is dynamically adjusted using an on-chip oscillator to maintain the desired output frequency. This allows the device to remain in a locked state without the need for external components. In PLL mode, a feedback loop is used to maintain the output frequency. This mode is typically used in high-performance applications such as mobile or cloud computing, where low jitter is crucial.

The CY2547FC features built-in power management, allowing the user to control their power consumption. The device can be programmed for dynamic power management, which allows for fine-grained control of its power consumption. This feature can also be used to reduce power consumption during idle periods, helping to reduce overall system power consumption. The device comes with a low-voltage power-saving circuitry, allowing it to maintain low power consumption even during periods of high activity.

The flexibility and performance offered by the CY2547FC make it well-suited for many of today’s most demanding clock applications. Whether it’s used in mobile or cloud-based applications, its superior phase noise performance helps maintain low jitter and high accuracy, keeping system performance consistent and reliable. The device’s low power consumption and programmable output frequencies make it ideal for use in high performance computing, communication, and military applications. Its wide range of features and excellent performance make the CY2547FC an ideal choice for clock generation systems.
