CY25403SXC-008 is a high performance, low-cost clock speed converter designed to bridge between asynchronous clock sources. It has a Core Timing Unit (CTU) that allows core timing up to 1.2GHz and up to 1GHz system-level timing on any asynchronous clock source. In addition, its Variable Speed Clock Generator (VSCG) features a wide range of frequencies for frequency synthesis or for higher frequency clock outputs.

Application Field

CY25403SXC-008 is an ideal solution for applications that require frequency conversion between different clock sources. It can efficiently bridge the gap between clock sources of different frequencies and provide a stable and accurate clock signal, making it suitable for communication, multimedia, and storage applications. Additionally, CY25403SXC-008 features on-chip voltage regulators and ESD protection, making it especially well-suited for portable or battery powered systems.

Working Principle

CY25403SXC-008 consists of two main functional blocks: the Core Timing Unit (CTU) and the Variable Speed Clock Generator (VSCG). The CTU is designed to synchronize timing signals between input and output clock domains, allowing up to a 1.2GHz core frequency. The CTU also provides a wide range of frequency and time scaling capabilities, allowing users to customize the clock settings to their specific needs.

The on-chip voltage regulators and ESD protection provide power efficient operation, as well as robust and reliable performance. Moreover, the built-in ESD protection eliminates the need for external components and allows for a small form-factor design.

The VSCG is used to generate higher frequency clock output by synthesizing multiple frequencies. This feature is beneficial for applications that require different frequency output for tasks such as signal processing. Additionally, the VSCG provides frequency synthesis and phase-locked loop (PLL) architectures that can be used for increased clock accuracy and better signal integrity compared to other methods.

Overall, CY25403SXC-008 is a versatile and low-cost solution that can bridge between different asynchronous clock sources while providing high speed, reliability, and power efficiency. It is an ideal solution for USB 3.0, SATA, PCIe, server/storage, and multimedia applications.
