100R matching resistors location
Posted: Mon Mar 25, 2024 9:29 am
Hello redpitaya team and users,
I would like to use the S1 S2 differential lines to test a LVDS ADC. Bank 34 is powered with VCCO=1.8V.
One needs a matching resistor to terminate an input pair.
On 125-14 schematic, R41, R42, R43 and R44 are used for this.
Where are they located on the pcb? I don't see them on the top or bottom silkscreens.
Thanks a lot for your answer,
Guillaume
