Bi-CMOS IC
LV25700PM For Car Radio
Single chip Tuner IC
Overview
The LV25700PM is a tuner IC for car radio, which incorporates an AM/FM Tuner, PLL, AM/FM Noise Canceller (NC),
FM Stereo-decoder (MPX), Multipath-noise Rejection Circuit (MRC), and RDS Demodulator Logic-controller. The basic
performance is based on the LV25210, and both adjustment-free operation and software control of the IF band variable
filter are possible.
This IC enables easy configuration of a low-cost, high performance analog tuner for OEM.
Functions
AM/FM + FE + PLL + IF + NC + MPX + MRC + RDS Demodulator + Logic-controller
Features
World-wide compatible tuners
World-wide compatible tuners can be configured and supplied with a single tuner IC.
FM is compatible with U.S., European, Japanese and Weather bands, while AM is compatible with LW, MW and SW.
High performance image cancel mixer incorporated in FM MIX.
PLL fast locking, RDS demodulator and AM/FM noise canceller incorporated
Self-contained type IF band variable filter incorporated
Detects any neighboring interfering FM stations and the modulation index, and enables various bandwidth settings of the
IF bandpass filter by using the software incorporated in the IC.
