SINGLE-CHIP BROADCAST FM RADIO TUNER
Rev.2.0–Mar.2011
1 General Description
The RDA58 02N series is the newe st genera tion
single-chip br oadcast FM stereo radio tuner with fu lly
integrated s ynthesizer, IF selectivity, R DS/RBDS an d
MPX decode r. The tuner uses the CMOS process,
support multi-interface an d require the least e xternal
component. The RDA580 2N series have three type
package size s , respective are RDA580 2N (QFN 4X4
mm, 24pins), RDA5802NS (QFN 3X3 mm, 20pins) an d
RDA5802NM (QFN 2X2 mm, 12pins). All these make it
very suitable for portable devices.
The RDA5802N series ha s a power ful low-IF d igital
audio processor , th is ma ke it ha ve o ptimum soun d
quality with varying reception conditions.
The RDA5802N series support frequency range is from
50MHz to 115MHz.
