The bonded channels consist of one master transceiver and 1 to 19 slave transceivers. The
CHBONDI/CHBONDO buses of the transceivers are daisy-chained together as shown in
Figure
When the master transceiver detects a channel bond alignment sequence in its data stream,

Whether a slave is a 1-hop or 2-hop slave, internal logic causes the data driven on the
CHBONDO bus from the master to be recognized by the slaves at the same time and must
