by an unused connector. The analog outputs should
not overlay the analog power plane to maximize
high frequency power supply rejection.
Analog Output Protection
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
idea to use output filters that are AC coupled to
avoid any problems.
ESD and Latch up Protection
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.
To prevent latch up, make sure that the analog
ground and the digital ground are at the same po-
tential, it also apply to the analog supply and the
digital supply, they must be at the same potential.
At power up, make sure that the analog and digital
supply are settled to their nominal voltage before
applying any signal pin.
To further prevent from external voltage anomalies
a 3.3 V zener diode should be applied. The diode
should be located after the filter, close to the con-
nector. Anode connected to ground and cathode
connected to the video output pin.
External DAC Output Filter
If an output filter is required, the low pass filter
shown in Figure 19 can be used.
