Analog Switch Usage in a Notebook PC Docking Bay

 

 

FSAV330 Quad SPDT Video Switch: Key Switch Specifications:

• Ron: 3 ohm typical at 4.5V
  
• Bandwidth: 300MHz minimum
  
• Cross-talk: -58db for 150 ohm load at 10MHz
  
• Differential gain: 0.64% Differential Phase: 0.1 degree
  

Applications & Advantage

• Note Book Computer Design
  
• Eliminate the expensive and redundant graphics chip on the docking bay Ultra low RON of FSAV330 eliminates the need for extra video buffer due to the fact of such a small signal柔attenuation
  
• Ultra low differential gain and phase maintains video signal integrity
  

FSAL200 10/100 Base-T Ethernet Switch

 

Key Switch Specification:

• -3db bandwidth: 350MHz
  
• Crosstalk: -70db at 30MHz
  
• On capacitance: 15pf
  

Advantage:

• Eliminate expensive and redundant Ethernet PHY on docking bay
  
• Low On capacitance and high bandwidth is desirable to minimize the signal edge distortion. Superior crosstalk performance further enhances the signal integrity
  
• Wide bandwidth is desirable to minimize the additive deterministic jitter
