LA1823
LA1823M
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)
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.
