ADV3200/32001 5V operation mode

Hi,

If I use the ADV 3200 with single supply at 5V, which is the logical level for digital I/O? In datasheet I see that is present the table with the value for 3V3 digital supply but I can't find the one for 5V.

moreover, is possible use 5V to supply analog power pins  (VPOS/VNEG) and keep at 3V3 the logical level (DVCC/DGND)?

regards,

Dario

    Hi Dario,

    The digital inputs and output are TTL logic so same values apply to DVCC = 5V


    moreover, is possible use 5V to supply analog power pins  (VPOS/VNEG) and keep at 3V3 the logical level (DVCC/DGND)?

    What do you mean by your second question? Are you saying +5V on the analog pins? if yes, that's not possible. Maximum voltage that the supply pin can handle is +3.3V(ADV3201).

  • Hi Gauzz,

    I would like to be able to use 0-5V as level for analog signal (our video signal is all positive so we don't need negative voltage) but I would like to have TTL logic at 3V3 level. So my second question is:

    It is possible use 3V3 as DVCC and 5V as VPOS to have logic TTL lavel at 3V3?

    but for my understanding, from first answer, the value of TTL is already 3V3 also with DVCC = 5V, right?

    regards,
