The same method can be used for biased signals. The
Pb and Pr channels are baised to set the DC level to
500mV.

Note:
1.
The video tilt or line time distortion is dominated by
the AC-coupling capacitor. The value may need to
be increased beyond 220μF to obtain satisfactory
operation in some applications.
Power Dissipation
The FMS6363A output drive configuration 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 JA
(1)
where:
Pd = PCH1 + PCH2 + PCH3
(2)
PCHx = VCC ICH - (VO
2/R
L)
(3)
where:
VO = 2VIN + 0.280V
(4)
ICH = (ICC/3) + (VO/RL)
(5)
VIN = RMS value of input signal
ICC = 22mA
VCC = 3.3V
RL = channel load resistance
Board layout can also affect thermal characteristics.
Refer to the Layout Considerations section for details.
The FMS6363A is specified to operate with output
currents typically less than 50mA, more than sufficient
for a dual (75) video load. Internal amplifiers are
current limited to a maximum of 100mA and should
withstand brief-duration short-circuit conditions. This
capability is not guaranteed.
