LA3401

VCO Non-Adjusting PLL FM MPX

Stereo Demodulator with FM Accessories

Overview

The LA3401 is a multifunctional MPX demodulator IC

designed for FM stereo electronic tuning. It features the

VCO non-adjusting function that eliminates the need to

adjust free-running frequency of VCO and the accessory

functions such as FM/AM input, FM/AM input changeover,

muting.

Applications

• Home stereos, portable hi-fi sets.

Functions

• VCO non-adjusting function.

• PLL MPX stereo demodulator.

• Gain variable type post amplifier.

• FM-AM changeover.

• Muting at the FM-AM changeover mode (changeover

mute)

• Muting function.

• Drive pin for external muting.

• VCO stop function.

• Separation adjust function.

• Muting at the VCC-ON mode.

• High voltage gain : Approximately 13dB (Commonto FM,

AM at standard constants) This gain can be varied by

external constants.

• Wide dynamic range : Distortion 1.0%/mono 800mV,

1kHz input (Post amplifier gain :

Approximately 13dB)

• The semifixed resistor (pin 4) for separation adjust can be

changed to a fixed resistor or can be removed.

• High ripple rejection : 34dB typ.

Features

• Non-adjusting VCO : Eliminates the need to adjust free-

running frequency.

• Good temperature characteristic of VCO : ±0.1% typ. for

±50°C change.

• Less high frequency distortion of stereo main signal

(0.07% typ. at f=10kHz) (Non-adjusting PLL makes it

possible to make the capture range narrower, providing

less high frequency beat distortion of stereo main sig-

nal.)

• Low distortion : Mono 0.01% typ.

Main 0.025% typ.

• High S/N : 91dB typ./mono 300mV input, LPF

94dB typ./mono 400mV input, LPF
