Remove R43 to have a single-ended clock output

Hi,
I want to feed a clock out of the RedPitaya via the sata connector S1 connector. The two clock pins of S1 are connected by a 100Ohms resistor (for differential clock output). However, since I want to have a single-ended output I would like to remove this resistor (R43 in the schematics). Unfortunately, it isn't depicted in the schematics file. Does anyone got an idea how to find it?

Hi,
it is on the bottom side of the board - see attached photo.
kind regards, Red Pitaya team

Hi,

I would like to remove R41 and R44 to use the SATA S2 interface as a SPI port.

Can you let me know if that is okay and how to read images from posts? I could not open the image from your last post.

Mike

Hello Mike,

I can give you the location of the two resistors.
Which board model are we talking about? STEMlab 125-14?

Please note that any non-Red Pitaya hardware modification will void the warranty, and we cannot guarantee support for modified boards.
