I'm interested in doing a project to read FM RDS data. Can anyone recommend good chips for both the FM receiver and RDS decoder?

For an FM receiver, I'd like to be able to control FM frequency (scanning of full range) from a microcontroller.

For the RDS decoder, I'm just interested in an IC that's readily available with a simple interface (e.g. I2C or SPI).

  • \$\begingroup\$ look for RDA5807M module also . It cheap and supports RDS. Note: This chip uses 3.3v logic. \$\endgroup\$ – Ryu_hayabusa Jul 11 '15 at 11:20

My apologies for the lateness in my reply, but there is a project in the July/August 2010 [just arrived yesterday...] edition of Elektor that may be of interest. It uses the Si4735 DSP receiver IC that can decode RDS.

Farnell part number for the IC is 1835849

  • \$\begingroup\$ Thanks for posting that link. I am tempted to have a go myself and make a simple radio. Will add it to the list of 'things to do'... :) \$\endgroup\$ – user1307 Sep 14 '10 at 12:23
