The FM transmitters (SI471x) take digital or analog audio input
and transmit, the SI4711 can even encode RDS/RDBS which
The FM receivers (SI470x) receive the signal and output analog
audio and SI4701 can decode RDS/RDBS and send that out
an SPI port.
The SI472x is both receiver and transmitter.
But last time I checked the distributor where I usually buy
parts only had the SI470x FM receivers, and I found some
of the other from other suppliers that were not local, I will
check availability later on tonight.
