RDA5802HS SINGLE-CHIP BROADCAST FM RADIO TUNER 1 Rev.1.1-Aug.2010 General Description The RDA5802HS is a new generation single-chip broadcast FM stereo radio tuner with fully integrated synthesizer, IF selectivity and MPX decoder. The tuner uses the CMOS process, support multi-interface and require the least external component. The package size is 3X3 mm and is completely adjustment-free. All these make it very suitable for portable devices. The RDA5802HS has a powerful low-IF digital audio processor, this make it have optimum sound quality with varying reception conditions. The RDA5802HS can be tuned to the worldwide frequency band, even support frequency range 50~65MHz. 1.1 z z Features CMOS single-chip fully-integrated FM tuner z z 3/4 Mono/stereo switch 3/4 Soft mute power supply when under normal situation 3/4 High cut 50 -108 MHz Support flexible channel spacing mode 3/4 Digital adaptive noise cancellation Total current consumption lower than 21mA at 3.0V Support worldwide frequency band 3/4 z z Low power consumption 3/4 z Figure 1-1.
