Part Number:TMS570LS3137-EP
Our customer has noticed from one of the application note for AM3358BGCZA80-EP device ( http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist ) that the SPI signals should have a 33ohm series resistor in line.
They could not find any such recomendation for the TMS570 processor. Would you please advise whether any such measures is necessary for the SPI clocks in TMS570LS3137-EP. If required what will be the criteria to choose the resistance value?
Thanks.
