LA1837M Overview
Key Features
- On-chip MPX VCO circuit (no external components required)
- Adjacent channel interference rejection function (third order and fifth order)
- Supports both the SD and IF counting technique (built-in SD speedup function)
- The AM and FM SD sensitivity can be set independently
- The AM and FM output levels can be set independently
- Improved basic FM reception performance. Functions
- AM: RF amplifier, mixer, oscillator, IF amplifier, detector, AGC, oscillator buffer, S-meter, narrow band SD, IF buffer
- FM IF: IF amplifier, quadrature detector, S-meter, SD, S curve detection, IF buffer output
