AM/FM 1 CHIP TUNER IC YD2149

Transcription

1 AM/FM 1 CHIP TUNER IC FUNCTIONS are AM/FM 1 chip tuner ICs, which are designed for portable Radios and 3V Head phone Radios. This is suitable for Digital Tuning System Applications. FM Local Oscillation is set up low relativity, for NEW FCC. For NEW FCC. Suitable for combination with Digital Tuning System which is included IF Counter. One terminal type AM/FM IF count output for IF counter of Digital Tuning system. FM: MHz(1/8 dividing) AM: 450kHz Built-in Mute Circuit for IF count output. For adopting ceramic Discriminator,it is not necessary to adjust the FM Quad Detector Circuit. Built-in FM MPX VCO circuit. Built-in one terminal type AM/FM Local Oscillator Buffer Output for Digital Tuning System Applications. Built-in 1/16 Pre-scaler for FM Local OSC Buffer. Built-in AM Low cut circuit. Low supply voltage range(vcc=3v,ta=25 ) Iccq(FM)=13mA(Typ) Iccq(FM)=8.5mA(Typ) Operating Supply voltage range :Vcc=1.8~7V(Ta=25 ) WuXi YouDa Electronics Co., Ltd Add: No.5 Xijin Road, National Hi-Tech Industrial Development Zone, Wuxi Jiangsu China Tel: Fax: Website: SHENZHEN OFFICE Tel: Fax: Ver of
