FSAV433 High-Bandwicth (550MHz) Three-Channel 3:1 Video Switch
August 2006
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 (RON) -3dB bandwidth: 550MHz Low power consumption (1A max)
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 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.
Applications
RGB Video Switch in LCD, Plasma, and Projection displays DVD-RW, notebook

Absolute Maximum Ratings
The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table defines the conditions for actual device operation
