Hello,
is the following res network needed for the 24 Bit data line?
Kind regards,
Marion
Hi Marion!
As long as you have the correct input voltages to the data inputs (1.8V or 3.3V), no pull-ups are needed. They are there to accommodate for voltages should the input voltages not be 1.8V or 3.3V.
Respectfully,
William Y.
HI William,
We have connected to RGB interface of soc on same PCB board with voltage group of 3.3V. So, It is not need to keep external PU in this case, Right?
Hi Diyora,
That is correct! This resistor network would not be needed.
For reference, there are many E2E questions that collaborate this use and goes over this exact question:
Thanks,
