I have two questions about Low Pass Filter at Full-Drive mode of ADV7392.Please refer attached file.
What power supply is VCC?
Shorting the analog outputs to ground when the DACS are enabled, I'm sure would damage the part. Regarding shorting to power supplies, I suspect that would damage the part too if it were outputting video at the time.
I could not coment on you external cicuitry. If you are thinking of supporting shart to battery and short to ground, have a look at this circuit note. It uses an external differential amplifier and implements low pass filtering too.
Thank you for your reply.
Question 1:When the output of ADV7392 connects to Vcc or GND accidently, can it cause to damage the ADV7392?
Question 2:There is ABSOLUTE MAXIMUM RATINGS description as follows:"Analog Outputs to AGND −0.3 V to VAA"
Please let me know what this description means.Does it mean "−0.3 V to VAA" can input to analog output pins?
The Analog outputs can be raised to 0.3V less than the VAA power supply.
Thank you for your reply.I understand about question 2.
Question 1:When the output of ADV7392 connects to Vcc or GND accidently, can it cause to damage the ADV7392?I think it damages the device.What do you think?
Thank you very much.
