RDA5802/03 SINGLE- CHIP BROADCAST FM RADIO TUNER R

2、ev.2.0Sep.2008 1 General Description The RDA5802/03 is a 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 4X4mm and i

3、s completely adjustment- free. All these make it very suitable for portable devices. The RDA5802/03 has a powerful low- IF digital audio processor, this make it have optimum sound quality with varying reception conditions. The RDA5802/03 can be tuned to the worldwide frequency band. 1.1 Features l C
