• ADV7511 video inputs accept logic levels from 1.8 V to 3.3 V?

    Although I have found the statement in the subject (video inputs accept logic levels from 1.8 V to 3.3 V) in the datasheet and elsewhere, I do not see how to do this.  The only electrical specifications I can find seem to indicate that the IO voltage can…

  • Device that is capable of translating i/o level of 1.8/3.3v to 3.3v.

    Hi,

    I'm looking for a device that is capable of translating 1.8/3.3v to 3.3v.

    The problem is, the circuit should be able to determine the i/o level and choose the supply voltage for translation.

  • AD9914 eval board schematic pin 57,AVDD, 1.8 v supply thru 600 Ohm Inductor?

    Dear Sirs,

    I was looking at the  AD9914 eval board schematic and Gerber files, and I had a question about pin 57. of the AD9914, AD9915.

    The data sheet seems to show that pin57  is AVDD, one of three pins for Analog Core Supply 1.8v.

    In the evaluation…

  • Could you pls recommend an IC for 125Mbps clk Dual direction IO 1.8 to 2.5 and also 2.5 to 1.8V

    I Have a 1000M Enthernet   Phy with 2.5 level  the FPGA IO is fixed  1.8V .      so  need a level Translation chip for all TX/RX CLK

    The  clk up to 125Mbps . time rise 1ns.

    could you please recommend one ?

    Thank you very much.

  • Hi all. I cant start working with ad9954 on my own board. Crystal quartz Geyer KX-13T 25 MHz with 40 pF loads. CLKMODESELECT connected to 1.8 V. But on the oscillograf there is nothing (25 MHz) on the REFCLK inputs!  Thank you.

  • RE: POWER-UP SEQUENCE of ADV7611.

    Is it possible that the 3.3 is feeding back into the 1.8v rail before the 1.8V becomes active?

    1) I would tie a schottkey diode from 1.8 to 3.3 to make sure the 1.8 never really exceeds the 3.3 rail

    2) is it possible the 1.8 comes up before your 3.3…
