Application Note

Integrated Load Detection for Video Drivers

In this two parts application note illustrating the power saving features on the new generation of video drivers, we will continue with the output load detection explanation. It’s costly and difficult for the chipset to detect the presence of a TV on the RCA connectors dedicated to the analog video channels, especially when the output of the video drivers need to be AC coupled. This load detection feature presented, answers the need by integrating the load detection into the video driver.

Integrated Input Auto-Detection Mode for Video Drivers

Consumer electronic applications have always been demanding in terms of space and cost reductions. In addition to these two requirements, power saving has become increasingly important in every system with the recent changes in ENERGY STAR® standards. These considerations constituted the main focus for the next video driver generation offered by onsemi.

SAG Correction Thumbnail

Application Note

SAG Correction

Video amplifiers are typically used to drive 75 Ω coaxial cables through an AC coupling capacitor. Unfortunately, in order to maintain the quality of the video signal this output capacitor must be made extremely large. However, as portable applications become more compact there are greater size restrictions to meet. A solution is a method called SAG correction, also known as SAG compensation, which is used in AC coupled video applications to allow a smaller output capacitor.
