Symbol meaning in the schematic
05-18-2020, 07:40 AM
Hi,
Iam having a hard time understand the "<<" and ">>" symbols in the Pine64 RockPro64 schematic: http://files.pine64.org/doc/rockpro64/ro...21-SCH.pdf
Here is a simple example for 2 pins:
PCIE_PWR: is marked with >> from the SoC, then with >> again on the EN pin of the the switch (or whatever). This clear that this pin in output (from the SoC side)
DVP_PWR: is marked with << from the SoC, then with >> on the EN pin of the the switch. This is confusing, Since it is connected to the EN pin of the switch, then it should be output, but why it is marked with << from from the SoC?
Can anyone please explain what these symbols supposed to mean?
TIA
