Design a Low-Jitter Clock for High-Speed Data Converters - AN800
ثبت نشده
چکیده
High-speed applications using ultra-fast data converters in their design often require an extremely clean clock signal to make sure an external clock source does not contribute undesired noise to the overal dynamic performance of the system. It is therefore crucial to select suitable system components, which help generate a low phase-jitter clock. The following application note serves as a valuable guide for selecting the appropriate components to design a low-phase noise PLL-based clock generator, suitable for ultra-fast data converters.

متن کاملReceiver Jitter Tracking Characteristics in High-Speed Source Synchronous Links
High-speed links which employ source synchronous clocking architectures have the ability to track correlated jitter between clock and data channels up to high frequencies. However, system timing margins are degraded by channel skew between clock and data signals and high-frequency loss. This paper describes how these key channel effects impact the jitter performance and influence the clocking a...
