MAX4989 Evaluation Kit
__________________________Quick Start
Required Equipment
? MAX4989 EV kit (2 USB cables included)
? User-supplied Windows M 2000/XP M or Windows
Vista M PC with a spare USB port
? User-supplied USB signal source (e.g., USB 2.0
flash drive)
Note: In the following sections, text in bold and under-
lined refers to items from the Windows operating system.
Procedure
The MAX4989 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Place a shunt across pins 2-3 of jumper JU1.
2) Place a shunt across pins 1-2 of jumper JU2.
3) Place a shunt across pins 2-3 of jumper JU3.
4) Connect the USB cable from the PC to the J1 USB
connector on the EV kit.
__Detailed Description of Hardware
The MAX4989 evaluation kit (EV kit) provides a proven
design to evaluate the MAX4989 Hi-Speed 2-of-4 USB
2.0 crosspoint switch. The EV kit contains two sub cir-
cuits, a typical USB crosspoint switch application (top
half), and a test circuit (bottom half).
Application Circuit
The application circuit is located at the top of the board.
Jumpers JU1, JU2, and JU3 are used to control the
switch connection (see Table 1). The MAX4989 is pow-
ered from the USB port that is connected to the USB
host. To use a user-supplied power supply, connect a 5V
supply to the VCC and GND pads. All signal traces in the
USB application circuit are 90 I differential controlled-
impedance traces .
Test Diagram Circuit
A separate test circuit is also provided at the bottom of
the MAX4989 EV kit for timing critical tests such as eye
diagrams. The test circuit is powered by applying a 2.7V
5)
6)
Verify that LED1 turns on.
Connect the USB signal source to the J3 USB con-
nector on the EV kit.
to 5.5V power supply at the VCC2 and GND2 pads.
Table 1 . Jumper Settings
7)
Go to the Windows System Properties window
(Windows logo key + Pause Break key from key-
board) to locate and open the Device Manager .
Under the Universal Serial Bus Controllers subject
directory, verify that the USB 2.0 signal source is
recognized through the USB port .
