august 2006 fsav433 high-bandwicth (550mhz) three-channel 3:1 video switch ? 2005 fairchild semiconductor corporation www.fairchildsemi.com fsav433 rev. 1.4.1 fsav433 high-bandwidth (550mhz) three-channel 3:1 video switch features ground between channels to optimize isolation and reduce hostile crosstalk -70db non-adjacent channel crosstalk at 30mhz 6.5 typical on resistance (r on ) -3db bandwidth: 550mhz low power consumption (1a max) applications rgb video switch in lcd, plasma, and projection displays dvd-rw, notebook description the fsav433 is an ultra-low power, high-bandwidth video switch specially designed for switching three ana- log video signals, including computer rgb and high-def- inition 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 negligible 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 notes: 1. pb-free package per jedec j-std-020b. application diagram order number package number pb- free (1) package description packing method fsav433bqx mlp020b yes 20-terminal depopulated quad very-thin flat pack no leads (dqfn), jedec mo-241, 2.5 x 4.5mm tape & reel fsav433mtc mtc20 yes 20-lead thin shrink small outline package (tssop), jedec mo-153, 4.4mm wide tube fsav433mtcx mtc20 yes 20-lead thin shrink small outline package (tssop), jedec mo-153, 4.4mm wide tape & reel
