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.)
