7.3.1. RX-Only and TX-Only Use Cases

In the TX-only and RX-only use cases, the unused configuration buses can be removed from the PHY Arbiter by unchecking the appropriate Enable in the PHY Arbiter configuration parameters, as shown in the following figures.

Note that RX-only means only the RX part of the particular transceiver is used and the TX is unused, and vice versa for TX-only. A design could have an RX PHY and Arbiter in RX only on one group of transceivers as well as a TX PHY and another Arbiter in TX only on a different group of transceivers.

The XCVR_RECONFIG_GROUP .qsf assignments are not necessary in this use case.
