RDA5807M SINGLE-CHIP BROADCAST FM RADIO TUNER
Rev.1.0–May.2011
1 General Description
The RDA5807M series is the newest generation single-chip broadcast FM stereo radio tuner with fully integrated 1 GND LOUT 10 synthesizer, IF selectivity, RDS/RBDS and MPX decoder. The tuner uses the CMOS process, support multi-interface 2 FMIN ROUT 9 and require the least external component. All these make it GND GND very suitable for portable devices. 3 RDA5807M 8 4 SCLK VDD 7 The RDA5807M series has a powerful low-IF digital audio processor, this make it have optimum sound quality with 5 SDIO RCLK 6 varying reception conditions. The RDA5807M series support frequency range is from Figure1-1. RDA5807M Top View 50MHz to 115MHz.
1.1 Features
CMOS single-chip ful y-integrated FM tuner Mono/stereo switch Low power consumption Soft mute Total current consumption lower than 20mA at 3.0V High cut power supply when under normal situation Programmable de-emphasis (50/75 s) Support worldwide frequency band Receive signal strength indicator (RSSI) and SNR 50 -115 MHz Bass boost Support flexible channel spacing mode Volume control and mute 100KHz, 200KHz, 50KHz and 25KHz Line-level analog output voltage Support RDS/RBDS 32.768 KHz 12M,24M,13M,26M,19.2M,38.4MHz Digital low-IF tuner Reference clock Image-reject down-converter Only support 2-wire bus interface High performance A/D converter Directly support 32Ω resistance loading IF selectivity performed internaly Integrated LDO regulator Fuly integrated digital frequency synthesizer 1.8 to 3.3 V operation voltage Fuly integrated on-chip RF and IF VCO MSOP－10pins Fuly integrated on-chip loop filter Autonomous search tuning
1.2 Applications
Support 32.768KHz crystal oscilator Celular handsets Digital auto gain control (AGC) MP3, MP4 players Digital adaptive noise cancelation Portable radios
