LV25700PM

Ordering number : ENA1709 Bi-CMOS IC LV25700PM Overview For Car Radio Single chip Tuner IC 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.
