Hot-selling and scarce SI4749-C10-GMR High-Performance FM RDS/RBDS Data Receiver QFN spot stock

Product Descriptions

The  Si4749  is  a  100%  CMOS  receiver  integratedcircuit (IC), offering the full receive functionality fromantenna   to   RDS/RBDS*   data   for   use   in   theautomotive and personal navigation markets . It is anideal companion RDS background data receiver forTraffic  Message  Channel  (TMC)  and  Open  DataApplications  (ODA)  applications frequently  used  inconjunction with GPS functionality or as an alternatefrequency (AF) scanner in automotive radios . It offersa    fully-integrated    advanced    decoder    for    theEuropean RDS* and the North American RBDS .  Itincludes demodulation, symbol decoding, advancederror correction, detailed visibility to block-error rates(BLER),   and   decoder   reliability,   synchronizationstatus,  and times . The  Si4749  provides  complete,decoded, and error-corrected RDS groups, up to 25groups at a time with associated BLER .
