The outputs can be AC-coupled since the output stage
can source and sink current as shown in Figure 6.
Coupling capacitors should be 220µF or greater to keep
the highpass filter formed by the 150Ω equivalent resis-
tance of the video transmission line to a corner frequen-
cy of 4.8Hz or below. The frame rate of PAL systems is
25Hz, and the frame rate of NTSC systems is 30Hz. The
corner frequency should be well below the frame rate.
Smartsleep only works with DC-coupled loads.
