USB Connections
A “B” type USB receptacle labeled “USB TO HOST” (J1) is
located on the left under-side of the board. This receptacle
should be connected using a standard USB cable to the
upstream USB host controller which is usually a PC
computer or hub. When this connection is made and the IN
logic control is driven HIGH, the ISL54209 device will go into
USB mode. The USB switches will be turned ON.
An “A” type USB receptacle labeled USB TO DEVICE (J2) is
located on the right underside of the board. The USB device
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.
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 ISL54209 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
(ie: MP3), 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
