? 2005 fairchild semiconductor corporation ds500896 www.fairchildsemi.com december 2004 revised february 2005 fsav450 800mhz quad spdt lcd/plasma video switch fsav450 800mhz quad spdt lcd/plasma video switch general description fsav450 is a 5v, high performance analog video switch specially designed for the route of analog rgb signals especially for applications with minimum cross-talk require- ments such as lcd panels and plasma tv with dual rgb or s-video inputs. the wide bandwidth (800mhz) of this switch allows signal pass with minimum edge and phase distortion while 75db non-adjacent channel crosstalk and 60db off isolation generates ignorable image noise between active channels. optimized differential gain and differential phases maintain the image integrity for video applications while low on resistance offers smallest signal insertion loss. features 60db off isolation at 10mhz 75db non-adjacent channel crosstalk at 10mhz 4 : typical on resistance (r on ) 3db bandwidth: 800mhz low power consumption (1ua max) control input: ttl compatible applications ? rgb video switch in lcd, plasma and projector displays ordering code: devices also available in tape and reel. specify by appending suffix letter ? x ? to the ordering code. pb-free package per jedec j-std-020b. note 1: dqfn package available in tape and reel only. order number package number package description fsav450bqx (preliminary) (note 1) mlp016e pb-free 16-terminal depopulated quad very-thin flat pack no leads (dqfn), jedec mo-241, 2.5 x 3.5mm fsav450qsc mqa16 16-lead quarter size outline package (qsop), jedec mo-137, 0.150" wide fsav450mtc mtc16 16-lead thin shrink small outline package (tssop), jedec mo-153, 4.4mm wide
