The recommended PCB layout for the AX88796BLF is to follow the guidelines provided in the datasheet, including keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the chip and the magnetics.
The AX88796BLF can be configured for half-duplex or full-duplex mode through the DUPLEX pin. For half-duplex mode, tie the DUPLEX pin to GND, and for full-duplex mode, tie it to VCC.
The AX88796BLF supports cable lengths up to 100 meters, but the actual maximum length may vary depending on the specific application and cable quality.
The AX88796BLF has a built-in power-down mode that can be controlled through the PWON pin. To implement power management, tie the PWON pin to GND to shut down the chip, and tie it to VCC to enable normal operation.
The AX88796BLF requires external magnetics to function properly. The recommended magnetics specifications are provided in the datasheet, including the inductance value, turns ratio, and core material.
