The first part of this article discussed the general aspects governing the need and the selection of solutions for analog video interfaces and detailed the most relevant technical aspects of the transmit side of such interfacesthe video DAC (VDAC). In this second part, we focus on the receiver side of the interfacethe video analog front end (video AFE or V-AFE).

Video AFE circuits (also known as video ADCs or video decoders) are essential components of digital home and personal entertainment systems. Despite growing use of emerging digital interfaces, analog video interfaces still play a prominent role in multimedia applications. Due to their high image quality and especially low power consumption compared with some popular digital video interfaces, there is a thriving market for consumer devices that use analog video as their primary connection.

Additionally, computer displays and home entertainment equipment will continue to support the large installed base of STBs, VCRs, DVD players, digital cameras and other equipment that only provide video in an analog format. To meet this requirement, SoC designers must incorporate high-performance video AFEs that can capture and digitize video from both xVGA computer video sources and a wide range of analog display formats, including the increasingly popular 1,080p high-definition TV (HDTV or simply HD) format.
