LV24003LP

Ultra-compact FM tuner IC for mobile set

Overview

The LV24003LP is FM tuner IC’s that requires absolutely no external components.

They incorporates not only the FM tuner functions but master volume control, tone control, buzzer, source selector,

Headphone amp and other functions as well in a compact VQLP package with dimensions of only 5mm×5mm×0.8mm.

These IC’s are simply ideal for incorporating FM tuner functions into mobile phones and other small mobile set where

space is always at a premium.

Functions

• FM FE

• FM IF

• MPX Stereo Decoder

• Tuning

• Volume control

• Tone control

• Buzzer

• Source selector

• Headphone amp

Features

• No external components

• No alignments necessary

• Fully integrated low IF selectivity and demodulation

• Built-in adjacent channel interference total reduction (no 114kHz, no 190kHz)

• Due to new tuning concept, the tuning is independent of the channel spacing

• Very high sensitivity due to integrated low noise RF input amplifier

• Very low power Standby mode. No power switch circuitry required

• MPX output for RDS application

• 3-wire bus interface (Data, Clock, NR-W)

• Digital AFC - Tuner locks to frequency after tuning sequence

• 8 level programmable Soft Mute

• 8 level programmable Stereo Blend

• In combination with the host, fast, low power operation of preset mode, manual search, automatic search and

automatic preset store are possible

• Covers all Japanese, European and US bands

Note1: Recommend to use 32Ω Headphone

Note2: Recommend to use Value of Inductor (L1, L2, L3) over 820nH for Headphone_output (pin 7, 8, 9)

Note3: In case of not use Headphone for ANT, Please Put Antenna Circuit ceparatly.

Note4: Vale of Extenal Component is just reference. Please set most sutable value under Acutual_operation.

Note5: In case of necessary BPF, Please put Between FM_ANT and HPA

Note6: We recommend to put C1 (100µF to 220µF) to Pin 9 for AC_GND

Note7: We recommend to put R1, R2, R3, R4 for interface_wire.

Note8: Please put Capacitor Between V

on application.

and GND also, put Capacitor Between V and GND as shown
