General Description

The MAX4886 evaluation kit (EV kit) is a fully assembled

and tested surface-mount printed-circuit board (PCB)

that contains two sub circuits, a typical 2:1 HDMI™

switch application (top half), and an eye diagram test

circuit (bottom half).

The MAX4886 HDMI application circuit evaluates the

MAX4886 high-speed HDMI/DVI™ 2:1 digital video

switch, combined with the MAX4929E for lower fre-

quency signals, to provide a full 2:1 HDMI application

circuit. The EV kit operates from a 5V DC power supply

and provides on-board 3.3V regulation. HDMI input/out-

put connections are also provided to easily interface

with HDMI-compatible devices. All signal traces in the

HDMI application circuit are 100Ω differential con-

trolled-impedance traces.

A separate test circuit is also provided at the bottom of

the MAX4886 EV kit for eye diagram evaluation using

SMA connections and 50Ω controlled-impedance traces.

Features

♦ Self-Powered from HDMI Source

♦ Optional 5V Power Supply

♦ Complete 2:1 HDMI Switching Circuit

♦ Eye Diagram Test Circuit with SMA Input/Output

♦ HDMI Inputs/Outputs

♦ Surface-Mount Construction

♦ Fully Assembled and Tested

MAX4886 Evaluation Kit Eye Diagram Test Circuit A separate test circuit is provided in the bottom section of the MAX4886 EV kit for eye diagram evaluation of the MAX4886 IC. This circuit provides differential SMA inputs and outputs with 50Ω controlled-impedance traces. R8–R11 can be populated to terminate as necessary. A regulated 3.3V power supply is required between VIN and GND2.
