Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluating the ADM2563E/ADM2863E 3 kV RMS/5.7 kV RMS, 500 kbps Signal and Power Isolated RS-485 Transceivers with 15 kV IEC ESD An on-board ADP7104 low dropout (LDO) regulator accepts FEATURES an input voltage of 3.3 V to 20 V and regulates the voltage to a Simplified evaluation of the ADM2563E and the ADM2863E selectable 3.3 V or 5 V supply for the V pin of the ADM2563E CC 500 kbps, signal and power isolated RS-485 transceivers and the ADM2863E. The LDO regulator can be bypassed to 2-layer PCB compliant to EN 55032/CISPR 32 Class B radiated power the VCC pin of the ADM2563E and the ADM2863E emissions directly. Footprint for 10.15 mm 10.05 mm, 28-lead SOIC W FP package with >8.0 mm creepage and clearance A screw terminal block on the evaluation boards allows connection On-board ADP7104 LDO regulator with jumper options for to the flexible V logic supply pin of the ADM2563E/ADM2863E. IO simplified evaluation in 5 V or 3.3 V configuration This connection allows the ADM2563E/ADM2863E to operate Flexible, low voltage VIO supply rail for interfacing with I/O with a digital input/output (I/O) voltage from 1.7 V to 5.5 V, nodes as low as 1.7 V which enables communication with nodes using either a 1.8 V ESD protection on RS-485 A, B, Y, and Z pins or 2.5 V power supply. The VIO pin can also be supplied from 12 kV IEC61000-4-2 contact discharge the ADP7104 regulated supply. 15 kV IEC61000-4-2 air discharge The EVAL-ADM2563EEBZ and the EVAL-ADM2863EEBZ come SMA connector for TxD input signal with options to evaluate the ADM2563E or the ADM2863E in an Optional on-board LTC6900 oscillator for providing TxD signal individual system. Digital and RS-485 bus signals are easily Screw terminal blocks for connecting power, digital signals, accessible via the screw terminal blocks on each evaluation board. and RS-485 signals Each digital input is configured via the on-board jumper options. Jumper selectable enable and disable for digital input signals Alternative methods can provide the transmit data input (TxD) Resistors and footprints for loopback test and termination signal to the ADM2563E or the ADM2863E. An LTC6900 Test points for measuring all signals oscillator is included on each evaluation board and can be EVALUATION KIT CONTENTS optionally configured to provide a clock signal for the TxD EVAL-ADM2563EEBZ or EVAL-ADM2863EEBZ digital input within a 10 kHz to 250 kHz range. For optimal signal integrity, use the on-board Subminiature Version A EQUIPMENT NEEDED (SMA) connector to connect an external data signal. Oscilloscope The EVAL-ADM2563EEBZ and the EVAL-ADM2863EEBZ Signal generator footprint for the full-duplex, isolated RS-485 transceivers is 3 V to 5.5 V supply in a 10.15 mm 10.05 mm, 28-lead, small outline, wide body with 1.62 V to 5.5 V supply fine pitch (SOIC W FP) package. The EVAL-ADM2563EEBZ DOCUMENTS NEEDED board is populated with the ADM2563E 3 kV rms, isolated RS-485 transceiver. The EVAL-ADM2863EEBZ is populated with the ADM2563E data sheet ADM2863E 5.7 kV rms, isolated RS-485 transceiver. The two ADM2863E data sheet evaluation boards differ only by the isolated RS-485 device GENERAL DESCRIPTION populated on U3. The EVAL-ADM2563EEBZ and the EVAL-ADM2863EEBZ allow For full details on the ADM2563E or the ADM2863E, see the for the simplified, efficient evaluation of the 3 kV rms ADM2563E ADM2563E or the ADM2863E data sheet, which must and the 5.7 kV rms ADM2863E 500 kbps signal and power be consulted in conjunction with this user guide when using the isolated, full-duplex RS-485 transceivers, respectively. EVAL-ADM2563EEBZ or the EVAL-ADM2863EEBZ. The ADM2563E and the ADM2863E each feature an integrated, isolated, dc-to-dc converter that provides power to the isolated side of the device with no additional ICs required.
