GENERAL DESCRIPTION
The EVAL-ADM2463EEBZ/EVAL-ADM2763EEBZ allow
simplified, efficient evaluation of the ADM2463E and
ADM2763E 5.7 kV rms, 500 kbps signal isolated RS-485
transceivers. The functionality of the EVAL-ADM2463EEBZ
and the EVAL-ADM2763EEBZ are the same. Figure 1 shows the
EVAL-ADM2463EEBZ and represents both evaluation boards.
The EVAL-ADM2463EEBZ/EVAL-ADM2763EEBZ come with
options for the evaluation of the ADM2463E and ADM2763E
devices in an individual system. Digital and RS-485 bus signals
are easily accessible via the screw terminal blocks on the
evaluation boards. Each digital input can be configured via the
on-board jumper options.
Two on-board ADP7104 low dropout (LDO) regulators accept
an input voltage of up to 20 V and output a range of selectable
supply voltages to the VDD1 pin and VDD2 pin, configurable via
jumper options. The LDO regulators can be bypassed to power
the ADM2463E and ADM2763E VDD1 supply pins and
VDD2 supply pins directly from an external power supply.
The flexible VDD1 pin primary side logic supply allows the device
to operate with a digital input/output (I/O) voltage from 1.7 V
to 5.5 V, which enables communication with modern nodes
using either a 1.8 V or 2.5 V power supply. The VDD1 pin can
also be supplied from the ADP7104 regulated supply.
Alternative methods can be used to provide the transmit data
input (TxD) signal to the device. An optional LTC1799 oscillator
is included on the evaluation boards and can be configured to
provide a clock signal as the TxD digital input within a 10 kHz
to 250 kHz range. A terminal block allows an easy wired
connection to a microcontroller or processor. For optimal signal
integrity, use the on-board Subminiature Version A (SMA)
connector to connect an external data signal.
The evaluation boards have footprints for the ADM2463E and
ADM2763E full duplex, signal isolated, RS-485 transceivers in
a 10.10 mm × 10 mm, 16-lead, standard small outline, wide
body (SOIC_W) package.
For full details on the ADM2463E and ADM2763E, see the
ADM2463E and ADM2763E data sheets, which must be used in
conjunction with this user guide when using the EVAL-
ADM2463EEBZ/EVAL-ADM2763EEBZ.

EVALUATION BOARD HARDWARE
SETTING UP THE EVALUATION BOARD
The EVAL -ADM2463EEBZ/E VA L -ADM2763EEBZ are used to
evaluate the ADM2463E and ADM2763E isolated RS-485
transceivers, which require a power supply on both sides of the
device. The evaluation boards are powered via the VDD1 and
VDD2 connections on the P5 and P6 screw terminal connectors.
The supply voltages connected to these terminals can either be
regulated or connected directly to the VDD1 pin and VDD2 pin of
the ADM2463E or ADM2763E. Insert the LK8 jumper into
Position E to power the VDD1 pin directly from the VDD1
connector. Insert the LK9 jumper into Position C to power the
VDD2pin directly from the VDD2 terminal on P6.
The two on-board ADP7104 voltage regulators can be configured
to provide a range of regulated supply voltages to the VDD1 pin
and VDD2 pin of the ADM2463E or ADM2763E. Various voltage
options can be selected using the LK8 and LK9 jumpers. The
VDD1 pin is fitted with a 10 µF decoupling capacitor (C3) and a
0.1 µF decoupling capacitor (C4). The VDD2 pin is fitted with a
10 µF decoupling capacitor (C6) and a 0.1 µF decoupling
capacitor (C5).
See Table 1, Table 2, and Table 3 for more details on the jumper
and power supply connections. The corresponding labeled test
points allow monitoring of the E VA L-ADM2463EEBZ/EVAL -
ADM2763EEBZ VDD1and VDD2 supply voltages.

INPUT AND OUTPUT CONNECTIONS
Digital input and output signals are connected via the P1 and P2
screw terminal blocks to allow wire connections from the EVAL-
ADM2463EEBZ/EVAL-ADM2763EEBZ to a signal generator or
microcontroller. The evaluation boards include screw terminals
for receiver data output (RxD), receiver enable (RE), and driver
enable (DE) on P1. Screw terminals for the TxD and receiver
invert (INVR) functions are also available on P2. Alternatively,
jumper connections can connect these signals to the VDD1 pin or
GND1pins of the ADM2463E or ADM2763E (see Table 1).
Connections to the RS-485 bus are made via the P3 and P4
screw terminal blocks. The EVAL-ADM2463EEBZ/EVA L -
ADM2763EEBZ have four bus input and output signals: Signal
A for the noninverting input signal, Signal B for the inverting
input signal, Signal Y for the noninverting output signal, and
Signal Z for the inverting output signal. The bus cables also
include a common ground connection and can be connected to
the P4 screw terminal block of the evaluation boards. Test points
are available on the evaluation boards and are appropriately
labeled for all digital and bus input and output signals.
RADIATED EMISSIONS
The ADM2463E or ADM2763E encodes data across the isolation
barrier using an amplitude shift keying (ASK) modulation
scheme, which is optimized for both high noise immunity and
minimal radiated emissions. The EVAL-ADM2463EEBZ/
EVAL -ADM2763EEBZ are 2-layer printed circuit boards (PCB)
that meet the EN 55032 Class B radiated emissions requirements
under full load while operating at a maximum data rate of
500 kbps. To maximize the margin to the EN 55032 Class B
specification, adhere to the following guidelines:
•Place a 0.1 µF capacitor (C4) between the VDD1 pin and
GND1pin.
•Place a 0.1 µF capacitor (C5) between the VDD2 pin and
GND1pin.
•Ensure that the decoupling capacitors are placed as close as
possible to the corresponding ADM2463E or ADM2763E
pins.
The EVAL-ADM2463EEBZ/E VA L -ADM2763EEBZ, designed
according to these guidelines, meet EN 55032 Class B
requirements with margin.
OTHER BOARD COMPONENTS
The EVAL -ADM2463EEBZ/E VA L -ADM2763EEBZ have
footprints for the R4 and R5 termination resistors. The 120 Ω
termination resistors are fitted to the evaluation boards, but these
resistors can be removed or replaced with a resistor of a different
value as needed. Insert the LK6 jumper to connect the R4 resistor
and add a 120 Ω load to the RS-485 receiver. Insert the LK7 jumper
to connect the R5 resistor and add a 120 Ω load to the RS-485
driver. The LK6 and LK7 jumpers can be inserted to connect the
RS-485 driver outputs to the RS-485 receiver inputs. When LK4,
LK5, LK6, and LK7 are inserted, the two 120 Ω termination
resistors are connected in parallel, resulting in a 60 Ω load on
the RS-485 driver.
Biasing Resistors for Bus Idle Fail-Safe
The ADM2463E or ADM2763E has a built in receiver fail-safe
for the bus idle condition, but there are footprints on the EVA L-
ADM2463EEBZ/EVA L -ADM2763EEBZ for fitting the R6 and R7
pull-up resistors to the VDD2 supply on the ADM2463E or
ADM2763E Pin A and Pin Y, as well as the R8 and R9 pull-down
resistors to the GND2supply on Pin B and Pin Z. These resistors
can be fitted if the user is connecting to other devices that require
external biasing resistors on the bus. The exact value required for
a 200 mV minimum differential voltage in the bus idle condition
depends on the minimum supply voltage and the termination
scheme. For 5 V transceiver operation, 1140 Ω is recommended.
For 3.3 V transceiver operation, 900 Ω is recommended.
See the AN-960 Application Note, RS-485/RS-422 Circuit
Implementation Guide, for more information about the bus idle
fail-safe.
On-Board LTC1799 Oscillator
An LTC1799 clock oscillator is provided on the EVAL-
ADM2463EEBZ/E VA L-ADM2763EEBZ to allow convenient
evaluation of the ADM2463E or ADM2763E without the need
for an external signal source.
To use the LTC1799 oscillator for evaluation, insert the LK10
jumper. This setting connects the clock oscillator output to the
ADM2463E or ADM2763E TxD input pin.
The sum of the R3 and R12 resistors can be used to configure
the switching frequency of the clock oscillator (fOSC) within the
100 kHz to 250 kHz range. The frequency is calculated using the
following equation:
( )

=

+

OSC
fNR R
10 k
10 MHz 3 12
where:
4 kΩ ≤ (R3 + R12) ≤ 1 MΩ.
N= 1 or 10
The value of N is controlled with the R18 resistor. When R18 is
not inserted, N = 10. Insert a 0 Ω resistor at R18 to set N = 1 for
higher frequency operation. The EVAL-ADM2463EEBZ/EVAL -
ADM2763EEBZ ship with N = 10 and R3 + R12 = 40 kΩ,
setting the oscillator output frequency to 250 kHz.
The LTC1799 oscillator is powered from the VDD1 supply, and
can only be used when the VDD1 supply voltage is between 2.7 V
and 5.5 V. By removing the 0 Ω R17 resistor, the LTC1799 can
be disconnected from the VDD1 supply.

ADP7104 LDO Regulator
The EVAL -ADM2463EEBZ/E VA L -ADM2763EEBZ feature two
on-board ADP7104 LDO regulators that allow flexible power
supply configurations during evaluation.
The VDD1 regulator, U1, is powered from the VDD1 terminal on
Connector P5, and is configured using the LK8 jumper. This
jumper position selects the regulator output to the VDD1 pin.
Options of 1.8 V, 2.5 V, 3.3 V, and 5 V are available. To bypass
the VDD1 ADP7104 regulator, U1, and power the VDD1 pin directly
from the VDD1 terminal, insert the LK8 jumper into Position E.
The VDD2 regulator, U3, is powered from the VDD2 terminal on
Connector P6, and is configured using the LK9 jumper. This
jumper position selects the regulator output to the ADM2463E
or ADM2763E VDD2pin. Options of 3.3 V and 5 V are available.
To bypass the VDD2 regulator, U3, and power the VDD2pin
directly from the VDD2 terminal, insert the LK9 jumper into
Position C.
Table 2 and Table 3 lists the supported power supply
configurations and the associated jumper configurations.
FULL DUPLEX RS-485 TRANSCEIVERS
LOOPBACK TEST
A loopback test can be set up with the EVAL-ADM2463EEBZ/
EVAL -ADM2763EEBZ by closing the LK4 and LK5 jumpers.
The details of this test are shown in Table 1 and in Figure 2. A
signal generator is connected to the TxD pin, which allows
verification of the bus signals and the receiver output. Note that
during the test, the jumper position for LK1 is Position C, LK2 is
Position A, and LK3 is Position C. See Table 2 for the jumper
configurations for different power supply configurations. The
LK6 and LK7 jumpers can be inserted to terminate the
transmitter and receiver with 120 Ω resistors. Connect both
jumpers when the board is configured in parallel by the loopback
to ensure that the test is conducted with a standard RS-485 load
of 60 Ω (bus terminated at both ends by 120 Ω).

IEC 61000-4-2 ELECTROSTATIC DISCHARGE
(ESD) PROTECTION
The EVAL -ADM2463EEBZ/E VA L -ADM2763EEBZ are tested
and verified to achieve protection against IEC 61000-4-2 ESD to
≥±12 kV (contact discharge) and ≥±15 kV (air discharge) on
the ADM2463E or ADM2763E Pin A, Pin B, Pin Y, and Pin Z.
The IEC 61000-4-2 ESD standard describes testing using two
coupling methods known as contact discharge and air discharge.
Contact discharge implies a direct contact between the discharge
gun and the equipment under test (EUT). The ADM2463E or
ADM2763E is tested using both of these methods.
During testing, the ADM2463E or ADM2763E Pin A, Pin B,
Pin Y, and Pin Z are subjected to at least 10 positive and 10
negative single discharges with a 1 sec interval between each
pulse. The highest specified IEC 61000-4-2 ESD test is Level 4,
which defines a contact discharge voltage of ±8 kV and an air
discharge voltage of ±15 k V.
