Are the digital outputs on your devices protected in any way from hort circuits?
LVPECL and CMOS outputs are NOT short circuit protected. If these outputs are grounded, internal damage may occur to the output stages.
The only outputs that are short-circuited protected are LVDS outputs. There's actually a specification in the data sheet for the maximum amount of current that flows under this condition.
so if i short the pixel output pins of the ADV7180 for example, to ground, i will likely damage the device even though abs max rating says min allowed is GND-0.3V
You posted this message to the clock PLL products, but it looks like this question belongs in the Audio/Video products forum. You may want to repost this question in the correct forum for the ADV7180 to be sure that your questions are answered.
For the clocking products, yes, the outputs are short-circuit protected.
