Revised May 2005 FSAV433 Low Voltage Ultra Low Power High Bandwidth (550MHz) 3-Port 3:1 Video Switch General Description Features The FSAV433 is an ultra low power high bandwidth video switch specially designed for the switching of three analog video signals, including computer RGB and high definition YPbPr signals. The wide bandwidth (550MHz) of this switch allows signal passage with minimum edge and phase distortion while 85dB nonadjacent channel crosstalk generates negligible image noise between active channels. Optimized differential gain and differential phases maintain the image integrity of video applications while low On Resistance offers low signal insertion loss. ■ Ground between channels to optimize isolation and hostile crosstalk ■ 85dB non-adjacent channel crosstalk at 10MHz ■ 6.5: typical On Resistance (RON) ■ 3dB bandwidth: 550MHz ■ Low power consumption (1uA max) Applications • RGB Video Switch in LCD, plasma and projection displays • DVD-RW, notebook Ordering Code: Order Number Package Number FSAV433BQX (Preliminary) (Note 1) MLP020B FSAV433MTC MTC20 Package Description Pb-Free 20-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 4.5mm 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Device also available in Tape and Reel.

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.
