LV24020LP

Ordering number : ENA0070A LV24020LP Overview Bi-CMOS IC Ultra-compact FM tuner IC for mobile set 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 Maximum supply voltage Symbol VCC max VDD max Digital input voltage VIN1 max VIN2 max Allowable power dissipation Operating temperature Storage temperature Pd max Topr Tstg Conditions Analog block supply voltage Digital block supply voltage Clock, Data, NR_W External_clk_in Ta ≤ 70°C Ratings 6.0 5.0 VDD+0.3 VDD+0.3 140 -20 to +70 -40 to +125 Unit V V V V mW °C °C Operating Condition at Ta = 25°C Parameter Recommended supply voltage Symbol VCC VDD Operating supply voltage range VCC op VDD op VIO op Interface supply voltage Conditions Analog block supply voltage Digital block supply voltage Ratings 3.0 3.0 2.7 to 5.0 2.5 to 4.0 1.8 to 4.0 Unit V V V V V Note: Power supply voltage VIO equal VDD, or VIO < VDD (VIO ≤ VDD) Interface Conditions at Ta = -20 to +70°C, VSS = 0V Parameter Supply voltage Digital part input Symbol VDD VIH VIL Digital part output IOL VOL Clock input frequency External clock frequency fclk fclk_ext High level input voltage range Low level input voltage range Low level output current Low level output voltage IOL=2mA 3wire_bus (29pin) clock frequency CLK_IN (31pin) frequency 32k Conditions Ratings min 2.5 0.7VDD 0 2.0 0.6 0.7 14M typ max 4.0 VDD 0.6 Unit V V V mA V MHz Hz Note: CLK_IN (31pin) can input sign wave.
