Hello,
In S32G-PROCEVB3-S board – REV A Schematics.pdf p. 17
U140 and U143 Multiplexer both have SD_MUX_TXN signals to A0_P.
Q1: SD_MUX_TXN is a signal input to Multiplexer, is that correct?
Q2: what is SD_MUX_TXN? where is it from S32G? I cannot find it in other pages.
Thanks
"connecting the output of U140 to the input of U143"
Thanks Daniel, it is clear.
Hi,
As told before, the signal is a point-to-point connection between U140 and U143. There is no purpose other than connecting the output of U140 to the input of U143.
As of who provides it, the specific signal of SD_MUX_TXN, it is being provided by the output of the multiplexer/demultiplexer U140. Depending on the setting of the multiplexer, can be either being routed to B0 or C0 of U140.
More information on regards of U140, we can recommend opening a ticket under the NXP online services, since this community is related to S32G rather than multiplexer/demultiplexer technology. We do apologize.
Please, let us know.
Hello Daniel,
What is the purpose of this signal?
Where/who provide it?
Thanks
Hi,
For the information provided under the schematic, since the signals are the transmission lines (TX), and the signals shown at the right side of the image go to the physical connector, we can say that the signals are seen as an output from U140.
Please, let us know.
Hello Daniel,
Thanks for the update.
What is the purpose of this signal?
From U140 perspective, is it a input signal?
Thanks
Hi,
We might be misunderstanding the overall inquiry, if so we apologize.
The signal you are referring to is a point-to-point connection between U140 and U143, as shown under the schematic:
These are not directly connected to the S32G.
Please, let us know.
