EVALUATION BOARD HARDWARE

SETTING UP THE EVALUATION BOARD

The EVAL-ADM2463EEBZ/EVAL-ADM2763EEBZ are used to
evaluate the

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 V

DD1

pin and V

DD2

pin of

the

. Insert the LK8 jumper into

Position E to power the V

DD1

pin directly from the VDD1

connector. Insert the LK9 jumper into Position C to power the
V

DD2

pin directly from the VDD2 terminal on P6.

The two on-board

voltage regulators can be configured

to provide a range of regulated supply voltages to the V

DD1

pin

and V

DD2

pin of the

. Various voltage

options can be selected using the LK8 and LK9 jumpers. The
V

DD1

pin is fitted with a 10 µF decoupling capacitor (C3) and a

0.1 µF decoupling capacitor (C4). The V

DD2

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 EVAL-ADM2463EEBZ/EVAL-
ADM2763EEBZ V

DD1

and V

DD2

supply voltages.

Table 1. Jumper Configurations

Link Jumper Connection Description

LK1

A

Connects the

RE input to the V

DD1

pin. This setting disables the receiver.

B

Connects the

RE input to the RE terminal on the P1 connector.

C

Connects the

RE input to the GND

1

pin. This setting enables the receiver.

LK2

A

Connects the

DE input to the V

DD1

pin. This setting enables the driver.

B

Connects the

DE input to the DE terminal on the P1 connector.

C

Connects the

DE input to the GND

1

pin. This setting disables the driver.

D

Connects the

DE input to the RE input signal. Therefore, the input for both RE and

DE is set by the LK1 jumper. This setting ensures that when the driver is enabled, the receiver is disabled, or

when the driver is disabled, the receiver is enabled.

LK3

A

Connects the

INVR input to the V

DD1

pin. This setting enables the receiver inversion

feature.

B

Connects the

INVR input to the INVR terminal on the P2 connector.

C

Connects the

INVR input to the GND

1

pin. This setting is used for normal receiver

operation.

LK4

Inserted

Connects the

Pin A to Pin Y.

Not inserted

Disconnects the

Pin A from Pin Y.

LK5

Inserted

Connects the

Pin B to Pin Z.

Not inserted

Disconnects the

Pin B from Pin Z.

LK6

Inserted

Connects the 120 Ω R4 termination resistor across the

Pin A and Pin B.

Not inserted

Disconnects the 120 Ω R4 termination resistor across the

Pin A and Pin B.

LK7

Inserted

Connects the 120 Ω R5 termination resistor across the

Pin Y and Pin Z.

Not inserted

Disconnects the 120 Ω R5 termination resistor across the

Pin Y and Pin Z.

LK8

A

Configures the

voltage regulator, U1, to supply a regulated 1.8 V to the

V

DD1

pin.

B

Configures the

voltage regulator, U1, to supply a regulated 2.5 V to the

V

DD1

pin.

C

Configures the

voltage regulator, U1, to supply a regulated 3.3 V to the

V

DD1

pin.

D

Configures the

voltage regulator, U1, to supply a regulated 5 V to the

DD1

pin.

E

Bypasses the

voltage regulator, U1, and powers the

DD1

supply pin

directly from the VDD1 terminal on the P5 connector.

LK9

A

Configures the

voltage regulator, U3, to supply a regulated 3.3 V to the

V

DD2

pin.

B

Configures the

voltage regulator, U3, to supply a regulated 5 V to the

DD2

pin.

C

Bypasses the

voltage regulator, U3, and powers the

DD2

supply pin

directly from the VDD2 terminal on the P6 connector.

LK10 Inserted

Connects the output of the

oscillator to the

TxD pin.

Not inserted

Disconnects the output of the

oscillator from the

TxD pin.
