A Method to Assess Analog Front-End Performance in Communication SoCs
By Manuel Mota, Product Marketing Manager, Synopsys
System designers need Analog Front-End (AFE) IP that can easily integrate into their SoC with less risk. Performance requirements have become even more challenging with the ever evolving technologies in smarter systems. Selecting an AFE IP and its components [Analog-to-Digital Converters (ADCs), Digital-to-Analog Converters (DACs) and Phase-Locked Loops (PLLs)] to meet SoC requirements for processing broadband signals is complex and can lead to over-specification and inefficient power consumption.
A simplified method is needed to determine if the electrical characteristics of any given AFE are adequate for the targeted application, such as broadband communications, in the context of wireless or wireline connectivity, cellular communications, and digital TV reception. Additionally, system designers need a tool to explore tradeoffs between relative performance and operating modes of different components to find the optimal performance, power, area and cost for their SoCs.
