Line Drivers / Switches
AKM has a wide range of product lineup in AV switch and AV line driver lineups, corresponding to user requirements finely for car navigations, STBs, digital TVs, DVD/BD player and recorders. The audio block includes pop noise free function when power-up/down the device, and the video block has crump circuits, video filters, 75ohm video drive circuit and video mute function, realizing simple and low cost system construction.
