The same method can be used for biased signals, with the
addition of a pull-up resistor to make sure the clamp never
operates. The internal pull-down resistance is 800kΩ
±20%, so the external resistance should be 7.5MΩ to set
the DC level to 500mV:

NOTE:
The video tilt or line time distortion is dominated by
the AC-coupling capacitor. The value may need to be incre-
ased beyond 220μF to obtain satisfactory operation in
some applications.
Power Dissipation
The FMS6143 output drive conguration must be considered
when calculating overall power dissipation. Care must be
taken not to exceed the maximum die junction temperature.
The following example can be used to calculate the power
dissipation and internal temperature rise.
TJ = TA + Pd θJA
(1)
where: Pd = PCH1 + PCH2 + PCH3 and
(2)
PCHx = VCC ICH - (VO2/RL)
(3)
where: VO = 2VIN + 0.280V
(4)
ICH = (ICC/3) + (VO/RL)
(5)
VIN = RMS value of input signal
ICC = 19mA
VCC = 5V
RL = channel load resistance
Board layout can also affect thermal characteristics. Refer
to the Layout Considerations section for details.
The FMS6143 is specied to operate with output currents
typically less than 50mA, more than sufcient for a dual
(75Ω) video load. Internal ampliers are current limited to a
maximum of 100mA and should withstand brief-duration
short-circuit conditions. This capability is not guaranteed.
