Ordering number : ENA0070A LV24020LP Bi-CMOS IC Ultra-compact FM tuner IC for mobile set Overview The LV24020LP is FM tuner IC’s that requires absolutely no external components. They incorporates not only the FM tuner functions as well in a compact VQLP package with dimensions of only 5mm×5mm×0.8mm. These IC’s are simply ideal for incorporating FM tuner functions into mobile phones and other small mobile set where space is always at a premium. Functions • FM FE • FM IF • MPX Stereo Decoder • Tuning Features • No external components • No alignments necessary • Fully integrated low IF selectivity and demodulation • Built in adjacent channel interference total reduction (no 114kHz, no 190kHz) • Due to new tuning concept, the tuning is independent of the channel spacing • Very high sensitivity due to integrated low noise RF input amplifier • Very low power Standby mode. No power switch circuitry required • MPX output for RDS application • 3-wire bus interface (Data, Clock, NR-W) • Digital AFC - Tuner locks to frequency after tuning sequence • 8 level programmable Soft Mute • 8 level programmable Stereo Blend • In combination with the host, fast, low power operation of preset mode, manual search, automatic search and automatic preset store are possible • Covers all Japanese, European and US bands Ver.2.23 71006HKIM No.A0070-1/9 LV24020LP Specifications Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings VCC max VDD max Digital block supply voltage Digital input voltage VIN1 max Clock, Data, NR_W VIN2 max External_clk_in VDD+0.3 Allowable power dissipation Analog block supply voltage Unit Maximum supply voltage 6.0 V 5.0 V VDD+0.3 V Ta ≤ 70°C Pd max V 140 mW Operating temperature Topr -20 to +70 °C Storage temperature Tstg -40 to +125 °C Operating Condition at Ta = 25°C Parameter Symbol Recommended supply voltage Operating supply voltage range Conditions Ratings Unit VCC Analog block supply voltage 3.0 V VDD Digital block supply voltage 3.0 V VCC op 2.7 to 5.0 V VDD op 2.5 to 4.0 V 1.8 to 4.0 V VIO op Interface supply voltage Note: Power supply voltage VIO equal VDD, or VIO < VDD (VIO ≤ VDD) Interface Conditions at Ta = -20 to +70°C, VSS = 0V Parameter Symbol Conditions Supply voltage VDD Digital part input VIH VIL IOL Low level output current Digital part output Clock input frequency External clock frequency Ratings min typ max Unit 2.5 4.0 V High level input voltage range 0.7VDD VDD V Low level input voltage range 0 0.6 2.0 V mA VOL Low level output voltage IOL=2mA 0.6 V fclk 3wire_bus (29pin) clock frequency 0.7 MHz 14M Hz fclk_ext CLK_IN (31pin) frequency 32k Note: CLK_IN (31pin) can input sign wave.
