Monolithic Linear IC

LA3430

PLL FM MPX Stereo Demodulator with Pilot Canceler for Car Stereo Use

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.

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.

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 13V).

•Good space factor due to single-end package.

•Easy to draw printed circuit pattern due to pin-to-pin space of 3mm.

LA3430

Specified Test Circuit

SW1 : For characteristics other than separation, place in the A position.

SW2 : For characteristics other than HCC, SNC, place in the A position.

SW3 : Forced monaural of reception mode.

Sample Application Circuit 1

Note 1 : The voltage applied to pin 10 must not exceed the voltage applied to pin 1.

*: When the LA1260 is used for the FM IF IC, R1 is 10kΩ and C1 is 0.1µF (Extension in capature range). (This also applies when an FM IF IC with a demodulation output similar to that of the LA1260 is used.)

No.1408–3/12

LA3430

Sample Application Circuit 2 : Combination of LA2110 and LA3430

Note 1 : The voltage applied to pin 10 must not exceed the voltage applied to pin 1.

*: When the LA1260 is used for the FM IF IC, R1 is 10kΩ and C1 is 0.1µF (Extension in capature range). (This also applies when an FM IF IC with a demodulation output similar to that of the LA1260 is used.)
