As System-on-chip (SOC) developers continue to look for ways to reduce cost and time to market, it is important to consider the different non-volatile memory (NVM) options that add flexibility to their products. Over the last few years, the NVM market has been flooded with new solutions. Now, having customers weigh the benefits of reliability, options, and costs during project development is even more critical. With antifuse vendors targeting a wider range of functionality and products, noting the reliability concerns of reaching hard breakdown (HBD) compared to soft breakdown (SBD) is vital.
Like most types of circuits, there is no such thing as a "one size fits all" PLL. This article will explore the trade-offs in PLL performance and design and look for a solution to most SOC PLL needs.
