The Si4769-A20-GMR is part of the Si476x radio receiver family, designed for high-performance automotive infotainment applications. It supports worldwide FM and AM radio reception, with frequency ranges of 64,Äì108 MHz for FM and 520,Äì1710 kHz for AM. This receiver includes advanced features such as RDS/RBDS demodulation and decoding, dynamic channel bandwidth control, and programmable audio processing capabilities, including noise blanking and soft mute. The device operates with a low-IF architecture, eliminating the need for external 10.7 MHz IF ceramic filters, which reduces the overall bill of materials and board space requirements. It provides both analog and digital (I¬=S) audio outputs, making it versatile for various automotive applications. The Si4769-A20-GMR is AEC-Q100 qualified, ensuring reliability in automotive environments, and operates within a temperature range of -40¬8C to 85¬8C. The compact QFN package measures 6 x 6 mm, facilitating integration into space-constrained designs.
