FSAV433 — High-Bandwidth (550MHz), 3-Channel, 3:1 Video Switch Features Description Ground between Channels to Optimize Isolation and Reduce Hostile Crosstalk -70dB Non-Adjacent Channel Crosstalk at 30MHz The FSAV433 is an ultra-low power, high-bandwidth video switch specially designed for switching three analog video signals, including computer RGB and highdefinition 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. On Resistance: 6.5Ω (Typical) -3dB Bandwidth: 550MHz Low Power Consumption: 1µA (Maximum) Applications RGB Video Switch in LCD, Plasma and Projector Displays DVD-RW The Fairchild switch family derives from and embodies Fairchild’s proven switch technology used for years in its 74LVX3L384 (FST3384) bus switch product.
