Monolithic linear IC
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.)

3. MPX
• Miniaturization of the required external components (nonadjusting 912 kHz VCO)
• Improved basic performance
— Pilot cancelation level (30 dB typ.)
— No variation in mono output level due to separation adjustment (subcarrier output level adjustment type
separation adjustment)
— A new SNC curve was developed.
— Built-in anti-birdie filters (114 kHz and 190 kHz)
— Improved high region separation characteristics
— Improved stereo signal-to-noise ratio
4. MRC
• Controls the SNC and HCC circuit control signals by detecting the field strength (S-meter) and multipath noise.

Note
The IC is forced to mono if a 1 Mresistor
is inserted between pin 5 and VCC.
14 HCC control input pin
13 SNC control input pin
HCC is off in AM mode.
Controls the sub output with an input of
between 0 and 1 V.
