ISP1301 USB OTG Transceiver Eval Kit User’s Guide
1. Introduction
The ISP1301 is a Universal Serial Bus (USB) On-The-Go (OTG) transceiver device that is fully compliant with
Universal Serial Bus Specification Rev. 2.0 and On-The-Go Supplement to the USB 2.0 Specification Rev. 1.0. It integrates a
USB full-speed and low-speed transceiver, and other analog components to fully support OTG functionality.
The ISP1301 is ideal for use in portable electronics devices, such as mobile phones, personal digital assistants
(PDAs), digital still cameras, and digital audio players. The ISP1301 acts as a physical layer to interface with any USB
OTG Controller.
The ISP1301 evaluation board is designed to evaluate the functions of the ISP1301 chip. The main components on
the board are: the ISP1301 (in HVQFN24 package), I2C master, USB mini-AB connector, analog audio interface,
and USB OTG controller interface. The operation mode of the ISP1301 can be configured through the I2C
interface. The OTG status and control registers in the ISP1301 can also be accessed through the I2C interface.
To verify the functions of the ISP1301 by using the DOS test program that is provided with the evaluation kit,
connect the ISP1301 evaluation board to the parallel port of a PC. To fully verify the functions of the ISP1301, a
USB OTG controller is used to connect to the ISP1301 board through the defined interface connector.
Figure 1-1: ISP1301 evaluation board PCB layout
2. System requirements
An x86 PC with DB-25 parallel port is required. The test program runs on DOS (or the command line in
Microsoft® Windows® 98). In the BIOS setting, select port address 378H for the onboard parallel port. The test
program is compiled using Turbo® C++ 3.0.

3. Configurations and settings
3.1. Power requirements
By default, the ISP1301 board is powered by a +5.0 V power supply through the DC jack (J12, inner +). The +5.0 V
power can also be supplied from the USB Type-B connector (J4). However, when J4 is connected to a USB port
on the PC, leave the USB mini-AB connector (J9) unconnected. If an external microprocessor is used to control
the I2C controller chip PCF8584 (U4), the +5.0 V power can also be supplied from pin 16 and pin 18 of the
microprocessor connector (J13).
When the +5.0 V power is correctly applied to the board, LED2 (green) will turn ON.

3.3. USB interface
There are three USB connectors on the ISP1301 evaluation board.
•
•
•
If an OTG Controller is connected to the ISP1301, the USB port functions as an OTG dual-role device
and only the mini-AB connector (J5) will be used.
If a Host Controller is connected to the ISP1301, the USB port functions as a host and only the Type-A
connector (J1) will be used.
If a Device Controller is connected to the ISP1301, the USB port functions as a device and only the Type-
B connector (J4) will be used.
You can use all the three ports at the same time. If you have a system that consists of a USB host port and a
separate device port, then the host port can be connected to J4 and the device port can be connected to J1 using
the standard USB cable. In such a case, the ISP1301 provides only OTG functions to the system; the transceiver
function of the ISP1301 is not used.
3.4. Audio interface
The ISP1301 evaluation board has an interface to support an analog audio carkit application. Connect:
•
•
•
The audio carkit to the mini-AB connector (J9) on the board;
The audio input line signal to the SPK LINE IN socket (J6) on the board;
The audio output line signalto the MIC LINE OUT socket (J7) on the board.
3.5. Reset
