FSAV450 800MHz Quad SPDT LCD/Plasma Video Switch
December 2004 Revised April 2005
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 requirements 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
s 60dB OFF Isolation at 10MHz s 75dB non-adjacent channel crosstalk at 10MHz s 4: typical On Resistance (RON) s 3dB bandwidth: 800MHz s Low power consumption (1uA max) s Control input: TTL compatible
Applications
* RGB Video Switch in LCD, plasma and projector displays

Note 2: 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 rating. The Recommended Operating Conditions tables will define the conditions for actual device operation. Note 3: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 4: Unused control inputs must be held HIGH or LOW. They may not float.
