MAX4983E Evaluation Kit
Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
? MAX4983E EV kit (USB cable included)
? A user-supplied Windows ? 2000/XP/Vista ? -compati-
ble PC with a spare high-speed USB port
? One USB 2.0 high-speed/full-speed device (i.e., USB
2.0 flash drive)
Procedure
The MAX4983E EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Verify that all jumpers (JU1, JU2, and JU3) are in
their default position, as shown in Table 1.
2) Connect the USB cable from the PC to the type-B
inputs by configuring jumper JU1, as shown in Table. 2.
The EV kit is powered from the type-B USB port (P1)
and provides an on-board regulated 3.3V supply to
power the MAX4983E IC. All USB signal traces are 90 ?
differential controlled-impedance traces.
The EV kit also includes an on-board VBUS power-
switching circuit that routes the USB power from port
P1 to either the P2 or P3 type-A USB ports. See the On-
Board VBUS Power Switching section.
USB Switch Control (CB)
The USB signals are routed between P1 and P2 or
between P1 and P3, depending on the state of the
MAX4983E DPDT switch. The DPDT switch is controlled
through jumper JU1 (Table 2).

Device Enable ( EN )
The MAX4983E is enabled/disabled by configuring
jumper JU2 (Table 3). When disabled, the MAX4983E
switches are placed in a high-impedance state.
