Evaluation Kit
General Description
Features
S Programmable Transceiver Supports
The MAX13170E/MAX13172E/MAX13174E evaluation kit
(EV kit) combines the MAX13170E multiprotocol clock/data
transceiver, the MAX13172E control transceiver, and the
MAX13174E cable terminator chips. This chipset forms a
complete software-selectable multiprotocol data terminal
equipment (DTE) or data communications equipment
(DCE) interface port that supports the V.28 (RS-232), V.11
(RS-449/V.36, EIA-530, EIA-530A, and X.21), and V.35
protocols. Internal charge pumps allow the EV kit to operate
off a single 5V supply.

Ordering Information
The EV kit was designed to take advantage of the chipset’s
flow-through pinout. The EV kit includes a 40-pin header
(logic signals), a female DB25 connector (protocol signals),
three SMA connectors (high-speed logic signals), and
scope-probe connectors for measuring the high-speed
data signals (logic and protocol signals).

corresponds to DCE mode and the bottom label
corresponds to DTE mode.
4) The green LEDs are attached to the receiver logic
outputs of the MAX13170E (U1) and the MAX13172E
(U2). The LEDs light up when the receiver logic
outputs are a logic-high. Verify that all green LEDs
light up when no signals are attached to the
DB25 connector. Note: The receivers have the true
fail-safe feature allowing 0V differential voltage to be
a valid state that forces the receiver outputs high.
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation. Caution: Do not turn on
power supplies until all connections are completed.
1) Verify that the default settings are configured
correctly, as shown in Tables 1, 2, and 3.
2) Connect a single 5V Q5% power supply between the
VCC and GND pads located in the lower-left corner
of the EV kit board.
5) The red LEDs are attached to the transmitter logic
inputs of U1 and U2. The LEDs light up when the
transmitter logic inputs are a logic-high. Verify that
none of the red LEDs light up when no signals are
connected to the 40-pin header (J1).
3) The yellow LEDs indicate the protocol mode of the
chipset. The LEDs light up when the correspond-
ing signal is a logic-high. Verify that all yellow LEDs

Evaluation Kit
Three SMA connectors (J3, J4, and J5) have also been
Detailed Description of Hardware
provided for driving the high-speed transmitter inputs of
the MAX13170E. The string of 16 LEDs across the top of
the board (D1–D16) are logic indicators. The red LEDs
(D1–D6) indicate the state of the transmitter inputs of the
MAX13170E and MAX13172E, the green LEDs (D7–D12)
indicate the state of the receiver outputs, and the yellow
LEDs (D13–D16) indicate the state of the protocol and
the protocol-termination modes. The LEDs light up when
their corresponding signals are a logic-high.
The MAX13170E/MAX13172E/MAX13174E EV kit was
designed to take advantage of the chipset’s flow-through
pinout. The logic signals have all been routed to the
40-pin header (J1) located on the left side of the EV kit
board. The protocol signals have all been routed to the
female DB25 connector (J2) located on the right side of
the board.
Various connectors have been added to the EV kit
to aid in taking quality measurements. Leave JU17
unconnected when measuring the supply current
of the chipset. Scope-probe connectors have been
added to measure the high-speed signals of the
transmitter inputs/outputs and receiver inputs/outputs
of the MAX13170E. The scope-probe connectors
located on the left side of the board are connected to
the logic input and output signals. The scope-probe
connectors located on the right side of the board are
connected to the protocol input and output signals.
The EV kit is extremely flexible and has several settings
for both the ICs as well as the board. The ICs have been
put into no-cable mode as the default mode. In no-cable
mode the user is able to program the desired proto-
col with an external controller connected to the 40-pin
header. The default mode settings are shown in Tables
1, 2, and 3. By default the SMA connectors (J3, J4, and
J5) are terminated with 50I and the control-transmitter
input lines are all connected low.

pin-strapped to a known state using Tables 7 and 8.
INVERT defaults to logic-low.
Configuration
The following provides a step-by-step procedure to aid
in configuring the EV kit. The EV kit is extremely flex-
ible and has several settings for both the ICs as well
as the board. The logic signals have all been routed to
the 40-pin header (J1) on the left side of the board. The
protocol signals have all been routed to the female DB25
connector (J2) on the right side of the board.
3) Clock/data transmitter input settings:
Connect the clock/data jumpers to the correspond-
ing state using Table 9. Force the inputs of all
unused transmitters low so their corresponding LED
indicators are off.
4) Control transmitter input settings:
The chipset protocol modes can be configured to
support V.28 (RS-232), V.11 (RS-449/V.36, EIA-530,
EIA-530A, and X.21), and V.35 protocols. All chipset
logic inputs, LED power, and shield ground connection
are jumper selectable. The board includes SMA connec-
tors (J3, J4, and J5) with optional 50I termination. The
board settings are separated in the following sections:
chipset protocol modes, clock/data transmitter input
settings, control transmitter input settings, SMA termina-
tion, and power/ground.
Connect the control jumpers to the corresponding
state using Table 10. Force the inputs of all unused
transmitters low so their corresponding LED indica-
tors are off.
5) SMA termination:
Connect the termination jumpers, depending on
whether the signal source needs to be terminated
with 50I, to the corresponding state using Table 11.
Leave unused transmitter input lines terminated so
the line is pulled down to a known state. When using
SMA termination, avoid connecting JU1, JU2, and
JU3 to VCC.
1) Connect a single 5V 5% power supply between the
VCC and GND pads located in the lower-left corner
of the EV kit board.
2) Chipset protocol modes:
6) Power/ground:
View the desired chipset protocol modes in Tables
4, 5, and 6. Connect the jumpers to the corre-
sponding state depending on whether the mode
lines are controlled by an external controller or are
Connect the power and ground jumpers according
to the desired operation using Table 12. Leave JU17
unconnected (open) when measuring the supply
current of the chipset.
