TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
The LA3430M (MFP-16 package version of LA3430) is
an MPX IC for FM car stereo use. It contains the VCO
non-adjusting function, skip noise eliminating function, and
pilot cancel function.
Functions
• VCO non-adjusting function.
• Pilot cancel function (Level follow-up type).
• Stereo noise control function (SNC function).
• High cut control function (HCC function).
• Stereo - monaural automatic select (Pilot input prioritized).
• VCO oscillation stop function.
• Forced monaural function for reception mode (Stereo lamp
unlighted, pilot cancel function and HCC function held).
This function is provided by disconnecting pin 14 from
VCC.

Features
• Non-adjusting VCO : Eliminates the need to adjust freerunning frequency.
• VCO is stable to ambient temperature changes : ±0.1 to
0.15% for ±50°C change.
• Low distortion (0.07% typ./300mV input mono).
• Good ripple rejection of power supply (35dB typ.).
• Wide operating voltage range (VCC=6.5 to 12V).
