RDA5807M SINGLE-CHIP BROADCAST FM RADIO TUNER 1 General

Description

Rev.1.0–May.2011 The RDA5807M 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 RDA5807M series has a powerful low-IF digital audio processor, this make it have optimum sound quality with varying reception conditions. The RDA5807M series support frequency range is from 50MHz to 115MHz. 1 2 3 4 5 GND FMIN GND RDA5807M SCLK SDIO LOUT ROUT GND VDD RCLK 10 9 8 7 6 Figure1-1. RDA5807M Top View 1.1  
