RF Receivers Procurement Notes
Verify the specific suffix 'AM' against official Skyworks documentation to confirm tray packaging and lead-free status. Ensure compatibility with the required 32-QFN footprint and thermal pad requirements during integration. Cross-reference the AEC-Q100 qualification if automotive reliability standards are mandatory for the target application environment.
RF Receivers Selection Notes
Select this component when dual-band AM/FM reception with RDS decoding is required in a compact form factor. The 32-QFN package suits space-constrained PCB layouts. Verify that the 2.7V to 5.5V supply range aligns with the system power architecture. Confirm that the -40°C to 85°C temperature rating meets environmental constraints.
RF Receivers Part Context
This part belongs to the SI4755 series of radio receivers from Skyworks Solutions Inc. The series includes variants such as SI4755-A40-GM and SI4755-A40-AMR, which differ primarily in packaging format. The SI4755 family provides integrated solutions for broadcast radio applications requiring high performance in small packages.
RF Receivers Replacement Considerations
SI4755-A40-GM is listed as a manufacturer-recommended alternative for the SI4744-C10-GM, indicating potential cross-compatibility within the broader SI47xx ecosystem. Verify pin-to-pin compatibility and software configuration differences before substituting.
