Design Notes
For optimal isolation performance, maintain a minimum creepage distance of 8 mm between the input and output sides on the PCB. Use a ground plane on each side of the isolation barrier, and avoid routing traces across the barrier. Place decoupling capacitors (0.1 Β΅F and 10 Β΅F) close to each VDD pin, connecting to the respective ground. The exposed pad should be soldered to a thermal pad connected to GND1 or GND2 for heat dissipation.
Route LVDS traces as differential pairs with controlled impedance (typically 100 ohms). Keep trace lengths matched and minimize vias to reduce signal skew. Place the isolator close to the LVDS connector or transceiver to minimize trace length. Avoid crossing the isolation barrier with any copper traces, as this can compromise isolation. Use a solid ground plane on each side, and consider adding stitching vias around the isolation barrier to reduce EMI.
The ADN4624BCPZ-RL7 operates from 1.7 V to 1.9 V supplies. Ensure that both VDD1 and VDD2 are within this range and are adequately decoupled. Use low-ESR ceramic capacitors (0.1 Β΅F and 10 Β΅F) placed as close as possible to the VDD pins. If the supply voltage is noisy, consider adding a ferrite bead in series. The device's power consumption is [DATA_NEEDED: power consumption], so ensure the supply can handle the load.
