Bi-CMOS IC

LV25300M

1-chip Tuner IC

Overview

The LV25300M integrates all six blocks (FM FE, FM IF, double conversion AM, AM-NC, and PLL diversity) required

in car radio tuner on a single ship.

Features

The LV25300M is a tuner system that supports the SANYO car audio DSP (SDRS300) that allows the creation of

standard tuner modules. Various setting changes can be performed with the software of the control microcontroller

according to the intended application. Small tuner modules can be developed with a smaller number of parts compared to

conventional tuners and at a lower total cost.

Moreover, the LV25300M comes with an antenna switching diversity function that switches two antennas in response to

various electric field changes while the vehicle is running, a malfunction prevention circuit that operates through antenna

switching frequency detection, and a weak electric field detection, and antenna fixing circuit that uses S meter voltage,

making stable reception possible.

Functions

FM F.E.

• Balanced input type double balanced mixer (FM mixer 1)

• Dedicated RF tuner DAC (8 bits × 2)

• Pin diode drive AGC output (antenna damping)

• MOSFET second gate drive AGC output

• Keyed AGC adjustment pin (3D-AGC)

• Differential IF amplifier (first IF amplifier)
