RDA5807MP
SINGLE-CHIP BROADCAST FM RADIO TUNER
1 Rev.1.0-July.2015 General Description The RDA5807MP series is the newest generation single-chip
broadcast FM stereo radio tuner with fully integrated synthesizer,
IF selectivity, RDS/RBDS and MPX decoder. The tuner uses the
CMOS process, support multi-interface and require the least
external component. All these make it very suitable for portable
devices.
The RDA5807MP series has a powerful low-IF digital audio
processor, this make it have optimum sound quality with varying
reception conditions.
The RDA5807MP series support frequency range is from 50MHz 1 FMIN LOUT 8 2 7 3 GND
