# Test Report of Fanout48

* Testing targets


## Testing targets

* Power
  * Checking USB Power is fine
    * (Source) A -> (Sink) C 
      * Theorely, max output is 5V/500mA from the charger
      * I tested with 2 ohm cement resistor, which output current is 2.2A (Theormly, should be 2.5A (5V))
        * 60 deg C
    * (Source) C -> (Sink) C: Type-C sink termination with 5.11k ohm pull down to CG1/CG2
      * 5V/3A output from the charger
  * If isn't, check EU terminate(5V) working fine
* 4x No 50 ohm test point 
  * Testing whether switches is working fine
* Insert fanout48 board to CDC-FE
  * test signal at terminated resistor(~50 ohm) of CDC-FE
