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 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
