2 Test Headers

The TUSB211RPTREVM includes headers for monitoring some device pins of the TUSB211A as well as power to the device.

Header J1:

This header is included to monitor the regulator output of the TUSB211A, this is for test purposes only and is not to be used as signal indicator.

Header J2:

This header is included to monitor the TEST pin of the TUSB211A, this is for internal test purposes only.

Header J3:

This header is included to monitor the CD pin of the TUSB211A, this header can be used as an external signal to indicate a connected device (Note: This signal is connected to the LED on the EVM which results in a lower voltage on the header. The resistor connecting this pin to the LED can be removed, if desired).

Header J4, J5:

These headers are included to monitor power to the TUSB211A, one side of header J4 connects to the power pins of the TUSB211A, the other connects to the output of the regulator (5 V to 3.3 V).

Header J6:

This header is included to monitor the EQ pin of the TUSB211A, refer to SW1 settings in Section 1 as well as the data sheet for details.
