GENERAL DESCRIPTION
The EVAL-ADM2463EEBZ/EVAL-ADM2763EEBZ allow
simplified, efficient evaluation of the
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
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
an input voltage of up to 20 V and output a range of selectable
supply voltages to the V
jumper options. The LDO regulators can be bypassed to power
the
ADM2463E
V
supply pins directly from an external power supply.
DD2
The flexible V
DD1
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 V
also be supplied from the
Alternative methods can be used to provide the transmit data
input (TxD) signal to the device. An optional
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
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.
