LA3430
Overview
The LA3401 is an MPX IC for FM car stereo use. It contains the VCO non-adjusting function, skip noise eliminating
function, and pilot cancel function and is packaged in a 16-pin SIP.
Features
Non-adjusting VCO : Eliminates the need to adjust free-running 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 13V).
Good space factor due to single-end package.
Easy to draw printed circuit pattern due to pin-to-pin space of 3mm.
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 10 from VCC.
