LV25400W

Overview

The LV25400W is a tuner front end IC that supports the Sanyo SDRS400 car radio DSP.

The LV25400W supports worldwide radio standards including the FM bands used in US, Europe, and Japan as well as the

LW, MW, SW, and FM weather bands. It adopts an image canceling mixer for the FM mixer and incorporates a fast PLL

locking function to support RDS. The LV25400W also supports automatic alignment using CCB bus control. It requires

external EEPROM.

The LV25400W can implement a DSP tuner at low cost with a minimal number of external components.
