DSP Tuner Front End
Overview
The LV25450PNW is a tuner front end IC that supports the Sanyo SDRS500 car radio DSP.
The LV25450PNW supports worldwide radio standards including the FM bands used in US, Europe, East-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. The LV25450PNW also supports automatic alignment using CCB bus control. It
requires external EEPROM.
The LV25450PNW can implement a DSP tuner at low cost with a minimal number of external components.
