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.)
