LA1867NM
Car Radio Single-Chip Tuner System
Overview
The LA1867M is a high-performance multifunction (FM-
IF, noise canceller, MPX and MRC) single-chip tuner IC
for use in car radios. High-quality tuners with superlative
cost-performance characteristics can be constructed easily
using this IC.
Functions
• FM-IF
• Noise canceller
• MPX
• MRC (multipath noise reduction circuit)
Features
• Forms a high-performance FM tuner when combined
with the Sanyo LA1193 FM front-end IC.
• Multiple functions, MRC circuit, dual diversity, and
RDS handling
• High performance, high sensitivity and high stability
(excellent temperature characteristics)
• High audio quality and noise reduction according to the
reception conditions.
• Miniaturization of the required external capacitors
(electrolytic capacitors no longer required)
• Easy adjustment (The SD, muting and SNC circuits are
separated.)
