If you disconnect the USB cable from J1 and take the IN pin
LOW, the IC will return to Audio mode. You can now plug the
headphone set into headphone jack, turn the audio source
ON to once again play music.
7. Remove the 0Ω resistors R
the performance (i.e. eye diagram, etc.) of the high speed
USB signal. Removal of these resistors disconnects the
headphone jack (J7) and BNC connectors (J8, J9, J14,
J15) from the USB differential lines. These components
when connected will degrade the USB signal. These
components will not be there in an actual application.
