FSAV450 800MHz 4 Channel 2:1 Video Switch
December 2004 Revised August 2005
FSAV450 800MHz 4 Channel 2:1 Video Switch
General Description
The FSAV450 is a high performance Quad SPDT (2-to-1 multiplexer/demultiplexer) video switch designed specifically for switching high definition YPbPr and computer RGB (up to UXGA) signals. The bandwidth of this device is 800MHz (Typ) which allows signals to pass with minimal edge and phase distortion. Image integrity is maintained with low crosstalk, high OFF-Isolation and low differential gain and phase. The low On Resistance (4: typical) minimizes signal insertion loss. Low voltage operation (3V), low power consumption (1uA maximum) and small scale packaging (including leadless DQFN) make this device ideal for a broad range of applications.
Features O 50dB OFF Isolation at 30MHz O 80dB non-adjacent channel crosstalk at 30MHz O 4: typical On Resistance (RON) O 3dB bandwidth: 800MHz O Low power consumption (1uA max) O Control input: TTL compatible Applications O 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.
