LA1823M

Ordering number : EN6854A LA1823 LA1823M Monolithic Linear ICs Single-Chip Tuner ICs for Use in Radio Cassette Recorder Overview The LA1823 and the LA1823M are single-chip tuner ICs that incorporate FM/AM and MPX circuits and support electronic tuning. The built-in MPX-VCO allows these ICs to be adjustment-free and to require no external components. Features AM, FM frontend/IF and MPX integrated in a single-chip. Built-in MPX VCO circuit Electronic tuning (AM oscillator output, AM/FM IF output) Adjustment-free FM detection (uses a ceramic discriminator) Packages : DIP24S (300mil) [LA1823] MFP24S (300mil) [LA1823M] Functions AM : RF amplifier, mixer, oscillator, oscillator buffer, IF amplifier, detector, AGC, IF count buffer output. FM-RF : RF amplifier, mixer, and oscillator. FM-IF : IF amplifier, quadrature detector, S-meter, and IF counter buffer output. MPX : PLL stereo decoder, stereo indicator, forced monaural, VCO on chip, Audio mute.
