LA1845NV

Ordering number : ENN*7931 www.DataSheet4U.com LA1845NV Monolithic Linear IC Single-Chip Home Stereo IC The LA1845NV is designed for use in mini systems and is a single-chip tuner IC that provides electronic tuning functions using SD/IF-count technique. It incorporates a pilot canceler and an adjustment-free MUX VCO circuit, thus allows additional parts to be reduced. Functions AM : RF amplifier, mixer, oscillator, IF amplifier, detector, AGC, SD, oscillator buffer, IF buffer, stereo IF output, AGC time constant switch FM IF : IF amplifier, quadrature detector, S-meter, SD (signal detection), S-curve detection, IF buffer output MPX : PLL stereo decoder, stereo display, forced monaural, VCO stop, audio muting, adjacent channel interference rejection function, pilot canceler Features Integrated MPX VCO (ceramic resonators are no longer required.) Built-in adjacent channel interference rejection function (114kHz, 190kHz) Supports both SD and IF-count techniques Both FM SD sensitivity and bandwidth can be set Pilot canceler built in.
