can be plugged directly into this receptacle or through a
standard USB cable.
In USB mode, the USB host controller and USB device will
be connected through the internal USB switches of the IC.
Unlike the audio switches, the USB switches are
bi-directional, which allow the host (computer) and
downstream USB device to both send and receive data.
Note: Before connecting the USB host controller at connector
J1, the headphones must be removed from the headphone
speaker jack, J7. This will prevent the audio load from
interfering with USB signal transmission. The main purpose of
the ISL54210 device is to allow the use of a common USB and
Audio Headphone Connector in Personal Media Players and
other portable battery powered equipment. Either a headphone
will be in the common connector to play music or a USB cable
from a computer will be in the common connector to transmit
digital data, such as music, into the memory of the Media
Player.
The BNC connector J8 (COM-) is in parallel with the D- line of
the J1 USB connector. The BNC connector J9 (COM+) is in
parallel with the D+ line of the J1 USB connector.
The BNC connector J14 (D-) is in parallel with the D- line of the
J2 USB connector. The BNC connector J15 (D+) is in parallel
with the D+ line of the J2 USB connector. If you want to use the
J14 and J15 BNC connectors, you must populate R1 and R2
with 0Ω resistors. These BNC connectors can be used to
connect test equipment to evaluate the performance of the IC.
