The same method can be used for biased signals with the addi-  
tion of a pull-up resistor to make sure the clamp never operates.  
The internal pull-down resistance is 800kΩ 20% so the exter-  
nal resistance should be 7.5MΩ to set the DC level to 500mV. If  
a pull-up resistance less than 7.5MΩ is desired, an external  
pull-down can be added such that the DC input level is set to  
500mV.  
Power Dissipation  
The FMS6346 output drive configuration must be considered  
when calculating overall power dissipation. Care must be taken  
not to exceed the maximum die junction temperature. The fol-  
lowing example can be used to calculate the FMS6346’s power  
dissipation and internal temperature rise.  
Tj = TA + Pd • ΘJA  
where Pd = PCH1 + PCH2 + PCHx  
and PCHx = Vs • ICH - (VO2/RL)

Layout Considerations  
General layout and supply bypassing play major roles in high  
frequency performance and thermal characteristics. Fairchild  
offers a demonstration board, FMS6346DEMO, to use as a  
guide for layout and to aid in device testing and characterization.  
The FMS6346DEMO is a 4-layer board with a full power and  
ground plane. Following this layout configuration will provide the  
optimum performance and thermal characteristics. For optimum  
results, follow the steps below as a basis for high frequency lay-  
out:

For multi-layer boards, use a large ground plane to help dissi-  
pate heat

For 2 layer boards, use a ground plane that extends beyond  
the device by at least 0.5”

NOTE: The video tilt or line time distortion will be dominated by  
the AC-coupling capacitor. The value may need to be increased  
beyond 220uF in order to obtain satisfactory operation in some  
applications.
