MAX9392 Evaluation Kit

Evluates:2/MAX93

General Description

Features

♦ Single 3V to 3.6V Supply Operation

♦ 1.5GHz Operation

The MAX9392 evaluation kit (EV kit) is a fully assembled

and tested PCB that simplifies the evaluation of the

MAX9392 1.5GHz, dual 2 x 2 crosspoint switch. The EV

kit accepts low-voltage differential signals (LVDS) or

high-speed transistor logic (HSTL) input signals and

converts the signals to LVDS outputs for each channel.

♦ 100Ω Controlled-Differential Signal Traces

♦ Supports Testing with Various Mediums

Differential Probes

The MAX9392 EV kit is designed with 100Ω differential

controlled impedance in a four-layer PCB. The board is

designed for direct differential probing of the LVDS

inputs/outputs. The EV kit operates from a single 3.3V

supply. The MAX9392 EV kit can also be used to evalu-

ate the MAX9393, which accepts LVPECL and CML

input signals.

MAX9392 Evaluation Kit

designed for direct differential probing at the LVDS

inputs/outputs and single-ended probing at the outputs

using the respective 2-pin headers. The EV kit operates

from a single 3.3V supply that provides 150mA of

output current.

Quick Start

Required Equipment

Before beginning, the following equipment is needed:

•

3V to 3.ꢁV, 500mA power supply (VCC)

LVDS signal generator (e.g., HP 8133A)

The MAX9392 EV kit consists of two independent LVDS

channels (A and B) that can be configured to operate

in one of three modes (crosspoint switch, 1:2 splitter, or

dual repeaters), using on-board jumpers. All differential

receiver inputs (IN_) are terminated with two series-

connected 49.9Ω resistors. Resistor PCB pads

R11–R18 are provided at the EV kit output channels for

application-dependent termination.

Digital sampling oscilloscope or communication

analyzer (e.g., CSA8000)

Procedure

The MAX9392 EV kit is fully assembled and tested.

Follow the steps below to verify board operation.

Caution: Do not turn on the power supply until all

connections are completed.

Power Supply

The MAX9392 EV kit can utilize up to three power sup-

plies. VCC is used as the power source for the

MAX9392 and the logic inputs. VTERM_IN and

VTERM_OUT PCB pads are used for input- and output-

termination voltages when evaluating the MAX9393.

VTERM_IN has a 0 to VCC - 1.2V input supply voltage

range. VTERM_OUT should be set to the respective

LVDS common-mode or bias voltage.

1) Connect the power supply to the VCC PCB pad.

Connect the ground terminal of the power supply to

GND PCB pad.

2) Set the signal generators to provide an LVDS signal

(this requires both a noninverting and inverting sig-

nal output from the signal generator).

3) Verify that a shunt is not installed at jumper JU1

(MAX9392 evaluation).

Input Signals

The MAX9392 accepts LVDS or HSTL differential input

signals. The differential high threshold is +100mV and

the differential low threshold is -100mV. The SMA input

connectors for the circuit are labeled INA_, INB_ (non-

inverting) and INA_, INB_ (inverting). All differential

inputs are terminated with two 49.9Ω resistors (R3–R10)

to create a 100Ω impedance termination. The input sig-

nals can be monitored with a differential signal probe

placed across header pins J1–J4 for the desired signal.

4) Verify that shunts are installed at jumpers JU2, JU3,

JUꢁ, and JU7 (all outputs enabled).

5) Verify that a shunt is not installed across jumper

JU4 and a shunt is installed across jumper JU5

(channel A configured in dual repeater mode).

Evluates:2/MAX93

ꢁ) Verify that a shunt is not installed across jumper

JU8 and a shunt is installed across jumper JU9

(channel B configured in dual repeater mode).

7) Connect the signal generator’s noninverting signals

to the INA_ and INB_ SMA inputs.

Output Signals

The four differential outputs can be accessed at header

pins J5–J8 with shielded twisted-pair cables or differ-

ential probes. Pin 1 is the inverting signal (OUT_) and

Pin 2 is the noninverting signal (OUT_). When testing

the EV kit using differential probes or twisted pairs,

populate resistor PCB pads R11–R18 with 49.9Ω

(0ꢁ03) surface-mount resistors. In addition to populat-

ing resistors R11–R18, terminate the twisted-wire pair

with a 100Ω resistor at the far end of the wire. All differ-

ential output pairs are laid out with equal trace length

having a maximum length difference of 10 mils and

100Ω controlled differential-impedance traces.

8) Connect the signal generator’s inverting signals to

the INA_ and INB_ SMA inputs.

9) Connect all the OUT_ SMA output connectors to the

digital oscilloscope inputs using 50Ω impedance

cables.

10) Enable the signal generators’ outputs.

11) Verify the signals by observing oscilloscope channels.

connectors to 50Ω impedance oscilloscope inputs.

Switch Configuration

(JU4, JU5, JU8, JU9)

Jumpers JU2, JU3, JUꢁ, and JU7 enable and disable

the EV kit’s corresponding outputs. Remove the shunts

from the jumpers to disable the output pairs. The differ-

ential output pairs assert to a differential low condition

when disabled. Install a shunt across the jumpers to

enable the outputs. The outputs can also be enabled or

disabled by applying a logic signal at pin 1 of jumpers

JU2, JU3, JUꢁ, and JU7. See Table 1 for proper jumper

settings for enabling and disabling the corresponding

outputs. Refer to the MAX9392 IC data sheet for proper

high and low logic levels at the enable inputs.

Jumpers JU4 and JU5 control the signal routing for

channel A differential inputs (INA0/INA0 and

INA1/INA1). Jumpers JU8 and JU9 control the signal

routing for channel B inputs (INB0/INB0 and

INB1/INB1). Channels A and B can be configured as

a 2 x 2 crosspoint switch, 1:2 splitter, or as dual

repeaters by configuring these jumpers. See Tables 2

and 3 for proper jumper settings for the different

switch configuration.

VERTM_OUT can also be used to set the LVDS output

termination voltages. See Table 4 for proper configura-

tion of jumper JU1 when evaluating the MAX9393.

Evaluating the MAX9393

The MAX9392 EV kit can be used to evaluate the

MAX9393 by replacing U1 with the MAX9393. Install a

shunt across jumper JU1, a resistor at R1, and a poten-

tiometer at R2, in addition to applying the desired termi-

nation voltage at the VTERM_IN PCB pad to evaluate

the MAX9393. Resistor R1 and potentiometer R2 are

used to provide current sinking capability to the EV kit

circuit when evaluating LVPECL, CML, and other VCC

referenced differential input signals. PCB pad
