YD2111 Datasheet | Wuxi Youda electronics

DESCRIPTION The YD2111 are AM/FM 1 chip tuner ICs, which are designed for portable radios and 3V headphone radios. FEATURES - For NEW FCC. - AM Detector coil, FM IFT, IF coupling condenser are not needed. - For adopting ceramic discriminator, it is not necessary to adjust the FM quad detector circuit. - Built-in FM MPX VCO circuit. - Built-in varactor diode for AFC. - Built-in AM low cut circuit. - Low supply current.（Vcc＝3V, Tamb=25℃） Iccq (FM)=9.0m A (typ.) Iccq (AM)=5.0m A (typ.) - Operating Supply Voltage Range: Vcc=1.8～7V（Tamb=25℃） BLOCK DIAGRAM 24 23 22 21 FM OSC 20 AM OSC AF FM MUTE AM DET FM MIX 2 3 4 5 AM IF 7 FM DET FM IF 8 9 LEVEL DET TUN LED 10 ST LED 11 12 19 18 17 AF VCO DIVIDE ST/MO FM/AM 16 15 14 13 DECODE AM MIX FM RF 1 AGC Wu Xi You Da Electronics Co., Ltd Add: No.5 Xijin Road, National Hi-Tech Industrial Development Zone, Wuxi Jiangsu China Tel: 86-510-85205117 86-510-85205106 Fax: 86-510-85205110 Website: .e-youda.
