9.1 Main Transmission Branch

The main transmission branch uses the embedded class-D PLC line driver to optimize performance in terms of efficiency and EMC compliance while reducing BOM cost and PCB complexity.

This is the default branch for single-band applications either in CEN-A, CEN-B or FCC bands.

ASO0 and ASO1 pins manage the filtering stage associated with the Main Transmission Branch. The PL460 is capable of automatically managing up to two external filters in the filtering stage, each filter associated to an ASOx line. In case of requiring only one filter in the coupling, both ASO lines must be connected together externally.

The ASIx pins indicate the status of the ASOx outputs, indicating whether the main branch is transmitting or not.
