(typical) ? -3db bandwidth: 550mhz ? low power consumption: 1a (maximum) applications ? rgb video switch in lcd, plasma and projector displays ? dvd-rw description the fsav433 is an ultra-low power, high-bandwidth video switch specially designed for switching three analog video signals, including computer rgb and high- definition ypbpr signals. the wide bandwidth (550mhz) of the switch allows signal passage with minimum edge and phase distortion, while ? 70db non-adjacent channel crosstalk generates neglig ible image noise between active channels. optimized differential gain and phases maintain the image integrity of video applications, while low on resistance offers low signal insertion loss. the fairchild switch family derives from and embodies fairchild?s proven switch technology used for years in its 74lvx3l384 (fst3384) bus switch product. ordering information part number operating temperature range package packing method fsav433mtcx -40 to +85c 20-lead, thin shrink small outline package (tssop), jedec mo-153, 4.4mm wide tape and reel figure 1. typical application diagram
