The EVAL-ADM2863EEBZ simplifies and facilitates the evaluation of the ADM2863E, a 5.7 kV rms, 500 kbps signal and power isolated, full-duplex RS-485 interface transceiver.

The ADM2863E incorporates an isolated DC-DC converter that supplies power to the isolated side of the EVAL-ADM2863EEBZ evaluation kit without requiring additional ICs.

The EVAL-ADM2863EEBZ incorporates an ADP7104 low-dropout (LDO) regulator that accepts input voltages from 3.3 V to 20 V and regulates them to either 3.3 V or 5 V, supplying the ADM2863E's VCC pin.

Screw-type terminal blocks on the EVAL-ADM2863EEBZ evaluation board connect to the ADM2863E's flexible VIO logic power supply pins. This connection enables the ADM2863E to operate with digital input/output (I/O) voltages ranging from 1.7 V to 5.5 V, facilitating communication with nodes using 1.8 V or 2.5 V power supplies. The VIO pins may alternatively be powered by the ADP7104 regulated power supply.

The EVAL-ADM2863EEBZ provides options for evaluating the ADM2863E within a single system. Digital and RS-485 interface bus signals are readily accessible via screw-type terminal blocks on each evaluation board. Each digital input is configured via on-board jumper options.

Alternative methods may be employed to supply the transmission data input (TxD) signal to the ADM2863E. Each evaluation board incorporates an LTC6900 oscillator, which can be selectively configured to provide a clock signal for the TxD digital input within the 10 kHz to 250 kHz range. For optimal signal integrity, external data signals may be connected using the on-board subminiature A (SMA) connectors.

Equipment required for EVAL-ADM2863EEBZ:
Oscilloscope
Signal generator
3 V to 5.5 V power supply
1.62 V to 5.5 V power supply
