| YOUDA INTEGRATED CIRCUIT YD2149 AM/FM 1 CHIP TUNER IC--YD2149 FUNCTIONS YD2149 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 Voltage 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: 1.3375MHz(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=1.87V(Ta=25) WuXi YouDa Electronics Co., Ltd Tel: Add: No.5 Xijin Road, National Hi-Tech Industrial Development Zone, Wuxi Jiangsu China 86-510-85205117 86-510-85205106 Fax: 86-510-85205110 Website: www.e-youda.com SHENZHEN OFFICE Tel 86-755-83740369 Fax 86-755-83741418 Ver 5.0 1 of 7 2006-7-10 YOUDA INTEGRATED CIRCUIT YD2149 BLOCK DIAGRAM WuXi YouDa Electronics Co., Ltd 2 of 7 Website: www.e-youda.com YOUDA INTEGRATED CIRCUIT EXPLANATION OF TERMINALS Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 CHARCTERISTIC RF GND FM-RF IN AM LOW CUT MIX OUT VCC AM IF IN FM IF IN GND AGC (AM AGC) QUAD R-OUT L-OUT Pin No. 13 14 15 16 17 18 19 20 21 22 23 24 CHARCTERISTIC LPF2 LPF1 MPX IN DET OUT IF REQ ST LED OSC OUT AM OSC FM OSC AM RF IN RF VCC FM RF OUT YD2149 MAXIMUM RATINGSTamb=25 SYMOL VCC ILED VLED PDNote Topr Tstg RATING 8 10 8 1200 500 -25+75 -55+150 UNIT V mA V mW CHARACTERSTIC Supply LED Current LED Votage Power Dissipation YD2111N YD2111F Operating Temperature Storage Temperature NoteDerated above 25 in the proportion of 9.6 mW/2149N mW/2149F. 4 ELECTICAL CHARACTERISTICS (Unless otherwise specified,Tamb=25,VCC=3V,F/E f=98MHzfm=1kHz FM IFf=10.7MHz,f=22.5kHz ,m=1kHz AM f=1MHz,MOD=30%,fm=1kHz MPX fm=1kHz) WuXi YouDa Electronics Co., Ltd 3 of 7 Website: www.e-youda.com YOUDA INTEGRATED CIRCUIT CHARACTERSTIC Supply Current Input Limiting Voltage F/E Local OSC Buffer Output Voltage 1 Local OSC Buffer Output Voltage 2 Input Limiting Voltage Recovered Output Voltage Signal To Noise Ratio FM IF Total Harmonic Distortion IF Count Output Frequency IF Count Output Voltage IF Count Output Sensitivity Gain Recovered Output Voltage Signal To Noise Ratio AM Total Harmonic Distortion Local OSC Buffer Output Voltage IF Count Output Voltage IF Count Output Sensitivity SYMOL Icc(FM) Icc(AM) Vin(lim) VOSC FM1 VOSC FM2 Vin(lim)IF VOD S/N THD fIF(FM) VIF(FM) IF sens(FM) GV VOD S/N THD VOSCAM VIF(AM) IF sens(AM) TEST CONDITION Vin=0, FM mode Vin=0, AM mode -3dB limiting fOSC=108.7 MHz fOSC=6.79375 MHz -3 dB limiting Vin=80dBV Vin=80dBV Vin=80dBV Vin=80dBV; SW7:ON Vin=80dBV; SW7:ON SW7:ON Vin=27dBV Vin=60dBV Vin=60dBV Vin=60dBV fOSC=1.45 MHz Vin=60dBV; SW7:ON SW7:ON 55 250 33 1.3373 250 42 20 60 23 75 37 200 MIN.
