Three New Tiny Switches Facilitate Video Switching
ON Semiconductor has just introduced four switches to facilitate many switching functions including composite video switching. One of the issues with today’s consumer products is they are getting so small, there is no room for traditional switches or extra sets of jacks needed for various functions. One solution is to permit one set of jacks to perform two functions, an input and an output. In this example, we show a Digital Video Camera with analog input/output requirements. Many consumers require the ability to transfer their old analog tapes to digital format, but this requires analog inputs on the camera. The size of today’s camera is so small that providing both input jacks and output jacks, requires too much space. One solution is to have an A/V jack which functions as either input or output. The onboard MCU can instruct the switch to be either an input or output.
