About This Manual
Thisistheuser’sguidefortheSN65LVDS387EVMandSN65LVDS386evalu-
ation modules (EVMs). It contains information on the evaluation modules
(EVMs)forTexasInstruments’SN65LVDS38716-channelLVDSdriverandfor
the SN65LVDS386 16-channel LVDS receiver.
Two separate EVMs are available, allowing each LVDS device to be tested
individually using a single EVM for that device. If both EVMs are used, the
LVDS output signals from the SN65LVDS387EVM 16-channel LVDS driver
can be connected to the LVDS inputs of the 16-channel LVDS receiver on the
SN65LVDS386EVM. This allows users to simulate performance of an LVDS
system. Recommended test equipment and evaluation and interconnect
guidelines are provided for both 16-channel point-to-point and multidrop
configurations. The EVMs are CE compliant for distribution within the
European Community.

Introduction
Introduction
Thisistheuser’sguidefortheevaluationmodules(EVMs)fortheTexasInstru-
ments’ SN65LVDS387EVM 16-channel LVDS driver EVM and the
SN65LVDS386EVM16-channelLVDS receiver EVM. One manual is used for
both EVMs because the boards are similar for both devices. The EVMs are
CE-compliant for distribution within the European Community.
Low-voltage differential signaling (LVDS), as documented in TIA/EIA-644, is
a balanced signaling method used for high-speed transmission of binary data
over copper. It is well recognized that the benefits of balanced-data transmis-
sion begin to outweigh the cost advantages of single-ended techniques when
signal-transition times approach 10 nS. This represents signaling rates ap-
proaching 30 Megabits per second (Mbps) Presently, LVDS devices operate
with signaling rates in the hundreds of Mbps. This performance is achieved
with reduced power consumption and reduced electromagnetic interference
(EMI) emissions compared to other data transmission standards, such as
TIA/EIA–422 and TIA/EIA–232 (also known as RS–232 and RS–422, respec-
tively), PECL, etc. Project collateral discussed in this user’s guide can be
downloaded from the following URL: http://www.ti.com/lit/zip/SLLU013.
Note: To Designers
Both EVMs use the same printed-wiring board (PWB). The 387 device is
mounted with the device’s pin 1 facing the top of the PWB, and the 386 is
mounted with the device’s pin 1 facing the bottom of the PWB.

The Evaluation Boards
Each EVM consists of a six-layer printed-wiring board (PWB). The LVDS
device and BergStickconnectors are on the top (connector side) of the
board. All other passive components are installed on the underside
(component side) of the PWB. A simplified input/output (I/O) block diagram of
the EVM is shown in Figure 2–1.

The SN65LVDS387EVM and the SN65LVDS386EVM are discussed in sec-
tions 2.1 and 2.2. Use of the schematics in Appendix A will facilitate under-
standing the detailed discussion that follows.

SN65LVDS387 16-Channel LVDS Line Driver
2-3
The Evaluation Boards
2.1 SN65LVDS387 16-Channel LVDS Line Driver
This 16-channel LVDS driver accepts 16 low-voltage TTL (LVTTL) inputs and
generates 16 LVDS differential outputs (please refer to the schematic in
AppendixI).Connectors P1/P2are theLVTTLI/O connectors.Connectors P3
through P7 are the LVDS I/O connectors. The LVTTL inputs can be provided
by any suitable source. As shipped, the SN65LVDS387EVM has 50-Ω
termination resistors (R33 through R48) installed on each LVTTL input line to
accommodate inputs from a pattern generator or other instrumentation that
has a 50-Ωsource impedance. If the LVTTL source and cable being used is
not a 50-Ωsource, then these resistors (resistors R33 through R48) need to
be removed. They are required to match the characteristic impedance of the
cable(andthesourceimpedanceofmostpatterngenerators).Theseresistors
are located on the back (under) side of the SN65LVDS386EVM, next to the
P1/P2 connector row.
The other optional components are resistors R1 through R32. Resistors R1
through R16 are left open on the SN65LVDS387EVM. These are used in the
LVDSoutputcircuitand, sinceLVDSlinesare normallyterminatedattheinput
to the receiver, these 100-Ωresistors are not installed on the EVM. If users
want to measure specific performance parameters on the ’387, then they are
responsible for installing 100-ohm resistors in R1 through R16. Zero-ohm
resistors are installed in R17 through R32, which are in series with the LVTTL
inputs to the SN65LVDS387. The remaining components are connectors for
Vcc and Gnd connections, and decoupling capacitors for the LVDS device.
These components are the same for both configurations of the EVM.
There are also four jumpers (JMP1 through JMP4 ) located next to the P1/P2
connector row. These jumpers control the enable and disable for each four-
channel (quad) section of the device. Each of these jumpers consist of three
pinsandajumpershort.Thecenterpinisconnectedtothedeviceandtheout-
er pins (top and bottom) are VCC and GND. The jumper short can be moved
socontactismadebetweenVCC andtheenable/disablepin,orbetweenGND
and the enable/disable pin. As shipped, the four jumper shorts are installed to
VCC so that all four sections of the device are enabled. A photograph of the
SN65LVDS387EVM is shown is Figure 2–2.

2.2 SN65LVDS386 16-Channel LVDS Line Receiver
The SN65LVDS386EVM accepts 16 LVDS inputs and generates 16 LVTTL
outputs (refer to the schematic in Appendix I). Connectors P3 through P7
(right-sideedge)acceptthedifferentialLVDSinputsandconnectorP1/P2pro-
vides the LVTTL output signals. The
as shipped configuration of the
SN65LVDS386EVMalsocontainsexternalresistorsrequiredforbasicopera-
tion and testing of the device. Resistors R1 through R16 are 100-Ωresistors
which terminate each LVDS input channel. These are installed on the under-
side of the SN65LVDS386EVM, very close to the input pins of the device.
TheLVTTL output-channelspath (etchon the PWB)contains two
pads where
external resistors may be installed. Resistors R17 through R32 are series re-
sistorswherezero-ohmresistorsarenormallyinstalled.Thesearefollowedby
resistors R33 through R48, which allow a pull-down resistor to be installed af-
ter the series resistor (R17 through R32). As shipped, these pull-down resis-
tors are not installed. The combination of these series (R17 through R32) and
pull-down resistors (R 33 through R48) allow the user to install a divider net-
workifdesired.Thismightbenecessaryiftheoutputsaretobemeasuredwith
aninstrument havinga50-Ωinputimpedance. Byinstallinga 475-Ωseriesre-
sistor and a 50-Ωpull down resistor, a 20:1 divider is created (the 50-Ωpull-
down in parallel with the 50-Ωinput impedance equals 25 Ω, plus the 475-Ω
series impedance of the instrument, for a total load of 500 Ωon the output of
thereceiver).Asshipped,thereisnoresistordividerinstalled,andeachdevice

(R17 through R32).
The remaining components are connectors for VCC and GND connections,
and decoupling capacitors for the LVDS device (these components are the
same for both EVM configurations).
There are also four jumpers (JMP1 through JMP4 ) located next to the P1/P2
connector row. These jumpers control the enable/disable for each four-chan-
nel (quad) section of the device. Each of these jumpers consist of three pins
and a jumper short. The center pin is connected to the device and the outer
pins (top and bottom) are VCC and GND. The jumper short can be moved so
contact is made between VCC and the enable/disable pin, or between GND
andtheenable/disable pin.As shipped,the jumpershortsareinstalled toVCC
so that all four sections of the device are enabled.

Pattern Generator
3-2
3.1 Pattern Generator
The SN65LVDS387 EVM requires a signal or pattern generator that can pro-
videatleastoneLVTTLinputsignaltothedevice.TheLVTTLsignallevelspro-
vided to the SN65LVDS387EVM must have a VIH = 2 Vdc minimum. Sixteen
simultaneous LVTTL inputs are required to fully exercise the device, so a pat-
tern generator with 16 parallel LVTTL outputs and a signaling-rate range up
to several hundred megabits-per-second (Mbps) is suggested. The Tektronix
HFS-series of pattern generators, or equivalent, can be used to provide the
LVTTLinputssignals.HFS-9DG1plug-incardsarerecommendedastheycan
be used to provide both single-ended inputs for the SN65LVDS387 driverand
differential inputs for the SN65LVDS386 receiver.
3.2 Oscilloscope and Scope Probes
The signaling rates and LVDS signal transitions are very fast (less than 1 nS).
To adequately monitor these signals will require an oscilloscope with a mini-
mumbandwidthof1GHz.Theprobesneedtohaveasimilarbandwidthtopre-
vent significant measurement errors. A Tektronix 784C oscilloscope with
P6243orP6245single-endedprobes,andP6247differentialprobes,orequiv-
alent, is suggested.
3.3 Power Supply
A single-output dc power supply is required to provide Vcc and Gnd to the
EVM. This supply is connected to J1 (Vcc) and J2 (GND) on the EVM. An ad-
justable dc range of 2–4 Vdc and a current of 200 mA dc is required. When
testing both the SN65LVDS387EVM and SN65LVDS386EVM together as a
system,eithera single500-mAdc-supply canbeused,or twoseparatepower
supplies may be used so performance with different Vcc levels on each EVM
may be evaluated.
3.4 Cables
There are no cables provided with either the SN65LVDS387EVM or the
SN65LVDS386EVM. When evaluating either the SN65LVDS387EVM or
SN65LVDS386EVMseparately,theonlycablesrequiredarethoseconnecting
the input signal source to the input of the EVM. When connecting the
SN65LVDS387EVMtotheSN65LVDS386EVMtoperformsystemtests,users
may evaluate system performance using different types and lengths of
cabling.ThisisdonebyinsertingthebareconductorintotheLVDSconnectors
between the two EVMs (the conductors have to be exposed by removing
approximately 1 to 1.5 centimeters of insulation from each conductor). It is
recommended to select a cable with a characteristic impedance (Zo) of
100Ω(±10%).AnycablewhichmeetstherequirementsofEIA-568ACategory
5 (CAT5) is recommended.

Operation
Operation
The SN65LVDS386 and SN65LVDS387 EVMs provide easy I/O connections
for instrumentation. This makes device testing quick and easy. Individual
channelscan be testedand parametersevaluated forspecific applications.In
addition,theEVMsaresmallandcompacttoallowtheentirePWBtobeplaced
ina smalltemperature chamber. Also,the I/Oconnectors andenablejumpers
are located away from the device, and all external resistors are located on the
oppositeside ofthe EVM.Thisalso allowsthe useof aforced-air temperature
controller (such as a Thermostream, or a Temptronics system). The user will
notice that the boards are designed such that the LVTTL I/O connections are
made on the left side of the EVM (P1 and P2) and the LVDS I/O connections
are made on the right side of each EVM (P3).

4.1 SN65LVDS387EVM Operation
The SN65LVDS387EVM is ready to be used as shipped. When connected to
the test instrumentation and 3.3-Vdc power (as described in section 3),
performancecan betested andobserved. AllI/Oconnectionsaremade using
standardBergSticksthat allowfast andeasy connections. Thesealso allow
direct connections to oscilloscope probes. BergSticksare also used for the
enable/disablejumperpoststoprovideeasyconnectiontoexternalequipment
if device response to enable/disable is required. The jumper shorts can be
manually placed in either the VCC position (enabled) or the GND position
(disabled), or the jumper post can be removed to allow connection to external
equipment. Note that there is no 50-Ωtermination onboard for the
enable/disable pins.
Basic tests of the SN65LVDS387 driver will consist of applying an LVTTL sig-
nalpatterntotheP1/P2inputconnectorandmonitoringtheoutputofthedriver.
Whentestedasastand-alonedevice,100-Ωterminationresistorscanbeadd-
ed to the scope probe, or individual 100-Ωtermination resistors can be
installed on the board (backside of the SN65LVDS387EVM) at R1 through
R16. The scope termination is recommended for high-signaling rates to elimi-
nate the stub effects caused by the PWB traces running to the P3 connector.

4.2 SN65LVDS386EVM Operation
Like the SN65LVDS387EVM, the SN65LVDS386EVM is shipped with all re-
quiredcomponentsalreadyinstalledontheboard,andisreadyfortesting.For
theLVDS386,differentialinputsneedtobeprovidedtosimulatethedifferential
output-voltage levels (Vod is nominally 400 mV) and common-mode output-
voltage inputs (nominally 1.2 Vdc) of an LVDS driver. These inputs are easily
connectedto the rightedgeP3-P7 LVDSside oftheSN65LVDS386EVM.The
LVTTLoutputsignalscanbemonitoredusingascopeprobeconnecteddirect-
ly to the P1/P2 connector pin.
As shipped, each LVDS input channel is terminated with 100-Ωresistors (R1
through R16) across the receiver inputs. These resistors are located on the
backside of the EVM near the input pins of the device. Each LVTTL output pin
is routed directly to the P1/P2 connector row. There are provisions on the
SN65LVDS386EVMtoinstallaseriesresistor andapulldownresistor.Thisal-
lows users to install a resistor divider on the output if required for testing the
device.But,asshipped,theseriesresistors(R17throughR32)havezero-ohm

ponents installed.
4.3 System Evaluation Using Both the SN65LVDS387EVM and
SN65LVDS386EVM
These EVMs has been designed to allow performance evaluation of both de-
vices when connected together. This allows users to perform tests using the
specific type and length of cable between the SN65LVDS387EVM and the
SN65LVDS386EVM. Users also has the option to install any specific connec-
torsand tousejumperwiresto theBergStickconnectors. However,it isrec-
ommendedthatanyjumperwiresbekeptasshortaspossibletominimizetheir
effect on system performance.
4.3.1 Point-to-Point Configuration
The majority of applications will have the outputs of the SN65LVDS387 driver
connected directly to an SN65LVDS386 receiver. This point-to-point configu-
ration can be used to perform higher-level system monitoring, such as chan-
nel-to-channel skew, crosstalk, and peak-to-peak jitter.
4.3.2 Multidrop Configuration
Using the SN65LVDS387EVM and SN65LVDS386EVM allows the perfor-
mance of multidrop tests. A multidrop configuration is defined as one in which
more than one receiver is connected to a single driver. There are many differ-
ent multidrop configurations that can be tested using both the SN65LVDS387
and SN65LVDS386EVM. Two possible configurations are shown in Figure
4–1. The termination resistors on the SN65LVDS386EVM will need to be re-
moved as required by the specific multidrop configuration.

Note:
When testing an SN65LVDS387EVM and SN65LVDS386EVM together,
make sure R1 through R16 (100 Ω) are not installed on the
SN65LVDS387EVM. Termination of the LVDS signal lines needs to be done
on the SN65LVDS386EVM.
