MAX3785 Evaluation Kit

General Description

Features

The MAX3785 evaluation kit (EV kit) simplifies evalua-

tion of the MAX3785 6.25Gbps equalizer. The EV kit

enables testing of all device functions. SMA connectors

with 50 controlled impedance to the MAX3785 are

provided for all input and output ports to facilitate con-

nection to high-speed test equipment.

Quick Start

Component List

1) Connect a +1.8V power supply to J1 (V ).

DESIGNATION QTY

DESCRIPTION

Connect the power supply ground to J2.

33µF 10% tantalum capacitor,

case B

AVX TAJB336M010R

2) Connect DC-blocking capacitors or bias T networks

to IN+ and IN- inputs. Then connect a differential

signal from 400mV

to 1600mV

to the inputs

P-P

using 50 cables. If not using DC-blocking capaci-

tors, then the high level for each input signal must

0.1µF 10%, 10V ceramic capacitors

be V

Test points

Digi-Key 5000K-ND

Warning: The SMA connectors are directly con-

nected to the chip’s inputs and outputs. To avoid

damage to laboratory equipment or device, always

use DC-blocking capacitors or bias T networks.

3) Connect DC-blocking capacitors or bias T networks

to OUT+ and OUT- outputs. Then connect signals

from the DC-blocking capacitors to an oscilloscope

with 50 input terminations.

4) At the signal source, start with a short, simple pat-

tern such as a 2⁷- 1 PRBS. The data rate can be

1Gbps to 6.4Gbps.

5) Evaluation: After the EV kit has been initially

checked out, evaluation can begin with a FR4 PC

board. Start with a board length of 20in and

progress to longer lengths. For data rates of

3.2Gbps and slower, the part equalizes board

lengths up to 40in. For data rates of 6.4Gbps and

slower, the part equalizes board lengths up to 30in.

When connecting the equalizer with the board, keep

the cables from the board to the equalizer as short

as possible.
