RX Channel Bonding
daisy chain. Daisy chaining is performed using the RXCHBONDLEVEL[2:0] ports to allow
additional pipeline stages between the master and the slave. The RXCHBONDO port of each slave
is used as a pipeline stage in the RXCHBONDO path from the master. Figure 4-48 and Figure 4-49
show two daisy-chain examples.
To set up a daisy chain, the GTP transceivers are first connected using RXCHBONDO and
RXCHBONDI to create a path from the RXCHBONDI port of each slave to the RXCHBONDO
