Description 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. Features CMOS single-chip fully-integrated FM tuner Low power consumption Support worldwide frequency band Support RDS/RBDS Digital low-IF tuner Image-reject down-converter High performance A/D converter IF selectivity performed internally Fully integrated digital frequency synthesizer Fully integrated on-chip RF and IF VCO Fully integrated on-chip loop filter Autonomous search tuning Support 32.768KHz crystal oscillator Digital auto gain control (AGC) Digital adaptive noise cancellation Mono/stereo switch Soft mute High cut Receive signal strength indicator (RSSI) and SNR Bass boost Volume control and mute Line-level analog output voltage Only support 2-wire bus interface Integrated LDO regulator Technical Specifications 2.7 to 3.3 V operation voltage Output Impedance: 32Ω Current consumption : lower than 20mA at 3.0V power supply when under normal situation frequency band: 50 -115 MHz Channel spacing mode : 100KHz, 200KHz, 50KHz and 25KHz Reference clock: 32.768 KHz 12M,24M,13M,26M,19.2M,38.4MHz Programmable de-emphasis : (50/75 µs) Module Weight: 0.3gm Applications Cellular handsets Portable radios PDAs, Notebook Mobile phones, mobile phones, intercom systems, mobile radio devices stereo radio.
