What is the value of the ADV7123 PSAVE pin internal pull-up resistor and what is its tolerance (+/-30% or else)?
Hi,
PSAVE Pull-Up Current typical value is 20 μA. Please refer Page3 at https://www.analog.com/media/en/technical-documentation/data-sheets/ADV7123-EP.pdf
Please note "PSAVE pull-up current is just the current needed to guarantee the device comes out of power save mode. A 10K pull-up would work fine .
Thanks,

Hi Poornima,
Thanks a lot.
What should be the maximum pull down resistor to insure power save mode at power up?
David.
Hi,
Could you please check the required Pullup/Pulldown resistor values in attached Design and Layout of a Video Graphics System for Reduced EMI (Rev. AN-333) at ADV7123 Datasheet and Product Info | Analog Devices
Thanks,
Poornima
Hi Poornima,
Sorry, but I didn't find the required Pulldown resistor values in attached documents.
Could you please recommend a value of the Pulldown resistor for the PSAVE pin?
Thanks.
Regards,
David Rolland.
Hi,
There is no such value provided in the ADV7123 related manuals, Could you please check those pull down values in same family parts of ADV7123.
Thanks,
Poornima
