Figure 6. AC-Coupling at the Outputs
AC-Coupling the Outputs
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 150
equivalent
resistance of the video transmission line to a corner fre-
quency of 4.8Hz or below. The frame rate of PAL sys-
tems is 25Hz, and the frame rate of NTSC systems is
30Hz. The corner frequency should be well below the
frame rate.
Power-Supply Bypassing and Ground
The MAX9512 operates from a single-supply voltage
down to 2.7V, allowing for low-power operation. Bypass

to GND with a 0.1μF capacitor. Place all external
components as close to the device as possible.
