With more and more multi-frequency clocks being used in today's chips, especially in the communications field, it is often necessary to switch the source of a clock line while the chip is running.

Although system timing creates no differentiation at the product level, as the world shifts from parallel to serial connections, timing requirements are becoming more critical than ever. A large ...

Today’s complex system boards often contain application-specific processors, high-speed general-purpose processors, and multiple system-on-a-chip designs. Each of these high-performance circuits may ...

Clock redundancy is required for many of today’s data-communication, networking, and computer systems. Any interruption due to component or board-level failure, or even simply regular system ...

Phase-Locked Loops (PLLs) are commonly used to perform a variety of clock processing tasks, such as clock frequency multiplication and clock deskewing. PLLs, like many other analog IP macros, come ...
