Abstract
A hybrid bus hub circuit and related apparatus are provided. The bus hub circuit can be configured to bridge a radio frequency front-end (RFFE) bus with a number of auxiliary buses of different types. Each of the auxiliary buses may support a fixed number of slaves identified respectively by a unique slave identification (USID). The hybrid bus hub circuit can be configured to selectively activate an auxiliary bus(es) for communication with the RFFE bus, thus making it possible to reuse a same set of USIDs among the auxiliary buses without causing potential identification conflict. As such, it may be possible to support more slaves in an apparatus with a single RFFE bus. As a result, it may be possible to reduce pin count requirement for an RFFE master and/or enable flexible heterogeneous bus deployment in the apparatus.
