Hello,

Can you please share the expected impedance of QO, QE, VSYNC, HSYNC, and CLOCK pins of this part?

Thank you!

Hello IK,

I was just wondering if the information can still be released before the week ends.
Can you please advise?

Thanks a lot!

Hi Elisha,

You can calculate this from Voh/Vol and Ioh/Iol for different ST settings in the table in section 7.5 of the datasheet. For ST = high and Dvdd = 3.3V, the typical high-level output impedance when Ioh = 10mA will be 90 ohms. Similarly, The low-level output impedance would be 61.54 ohms when Iol = 13mA.

I.K.
