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 800k ±20% so the exter-
nal resistance should be 7.5M to set the DC level to 500mV. If
a pull-up resistance less than 7.5M is desired, an external
pull-down can be added such that the DC input level is set to
500mV.

The same circuits can be used with AC-coupled outputs if
desired.

NOTE: The video tilt or line time distortion will be dominated by
the AC-coupling capacitor. The value may need to be increased
beyond 220F in order to obtain satisfactory operation in some
applications.
Power Dissipation
The FMS6690 output drive conguration 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 FMS6690’s power
dissipation and internal temperature rise.
Tj = TA + Pd ΘJA
where Pd = PCH1 + PCH2 + PCHx
and PCHx = Vs ICH - (VO
2/R
L)
where
VO = 2Vin + 0.280V
ICH = (ICC / 6) + (VO/RL)
Vin = RMS value of input signal
ICC = 60mA
Vs = 5V
RL = channel load resistance
Board layout can also affect thermal characteristics. Refer to the
Layout Considerations Section for more information.
Layout Considerations
General layout and supply bypassing play major roles in high
frequency performance and thermal characteristics. Fairchild
offers a demonstration board, FMS6690DEMO, to use as a
guide for layout and to aid in device testing and characteriza-
tion. The FMS6690DEMO is a 4-layer board with a full power
and ground plane. Following this layout conguration will pro-
vide the optimum performance and thermal characteristics. For
optimum results, follow the steps below as a basis for high fre-
quency layout:
Include 10F and 0.1F ceramic bypass capacitors
Place the 10F capacitor within 0.75 inches of the power pin
Place the 0.1F capacitor within 0.1 inches of the power pin
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”
Minimize all trace lengths to reduce series inductances
