SVI2.0 voltage #4

Open DrmnSamoLiu opened 5 months ago

DrmnSamoLiu commented 5 months ago

Just curious, it seems that SVI2.0 bus communicates over 1.8v voltage level. (At least on my motherboard.) From the schematics you provided, svd_out and svc_out are both connected to Vcc with a pull up resistor. On a teensy 4.0 board there are only 5v and 3v outputs, is it safe to use on 1.8v SVI2 bus? Or a logic level shifter is also needed? Thanks a bunch!
