LV25300M Datasheet | SANYO

.DataSheet.co.kr Ordering number : EN- 8320A LV25300M Overview Bi-CMOS IC 1-chip Tuner IC 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 pared to conventional tuners and at a lower total cost. Moreover, the LV25300M es 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) Continued on next page. - - CCB is a registered trademark of SANYO Electric Co., Ltd.
