presented by an unused connector. The analog out-
puts should not overlay the analog power plane to
maximize high frequency power supply rejection.
9.5.
To minimize the possibility of damage to the ana-
log output sections, make sure that all video con-
nectors are well grounded. The connector should
have a good DC ground path to the analog and dig-
ital power supply grounds. If no DC (and low fre-
quency) path is present, improperly grounded
equipment can impose damaging reverse currents
on the video out lines. Therefore, it is also a good

All MOS devices are sensitive to Electro Static
Discharge (ESD). When manipulating these devic-
es, proper ESD precautions are recommended to
avoid performance degradation or permanent dra-
mage.

If an output filter is required, the low pass filter
shown in Figure 30 can be used.
