MAX12934/MAX12935 Evaluation Kits

Detailed Description of Hardware

The MAX12934XW and MAX12935XW EV kits are powered

from two external adjustable power supplies as described

below.

External Power Supplies

Power to the MAX12934XW and MAX12935XW EV kits

are derived from two external sources which can both be

between +1.71V and +5.5V. Connect one source between

can be set independently and can be present over the

entire range from 1.71V to 5.5V, regardless of the level or

presence of the other supply. The MAX12934/MAX12935

level-shifts the data, transmitting them across the isolation

barrier.

Two SMA connectors on each side of the board allow

easy connections to signal generator(s) and oscilloscope.

A typical application diagram is shown in Figure 2.

Decoupling Capacitors

Each power supply is decoupled with a 10µF ceramic

capacitor placed close to the power supply test point, and

a 0.1µF ceramic capacitor placed close to U1.

Termination

Each input and output has an unpopulated 0805 SMT

resistor (R1–R4) and a 0805 SMT capacitor (C1, C2, C6,

C7) to GND_ to allow termination based on customer

requirements.
