General Description

The MAX4983E evaluation kit (EV kit) provides a proven

design to evaluate the MAX4983E high ESD-protected

double-pole/double-throw (DPDT) switch. The EV kit is

designed to demonstrate the MAX4983E ICs used in

USB 2.0 high-speed (480Mbps) switching applications.

The EV kit routes a single USB signal between one of

two type-A USB ports.

The MAX4983E EV kit PCB comes with a MAX4983EEVB+

installed.

Features

o USB Powered (Cable Included)

o Complete USB 2.0 (480Mbps) Switching Circuit

o On-Board VBUS Power-Switching Circuit

o Lead-Free and RoHS Compliant

o Proven PCB Layout

o Fully Assembled and Tested

MAX4983E Evaluation Kit On-Board VBUS Power Switching The EV kit includes a power-switching circuit, designed with n-channel and p-channel MOSFETs, that routes the P1 USB bus voltage (V1) to the P2 or P3 USB ports. The power-switching circuit is controlled by the state of the CB control pin, which is set through jumper JU1. See Table 5 for operation. Table 4. Jumper JU3 Function SHUNT POSITION VCC SUPPLY 1-2* On-board supply Device powered by on-board linear regulator (3.
