RF Transmitter Procurement Notes

Verify component status as the manufacturer has issued discontinuation notifications. Confirm availability through authorized distributors only. Ensure compliance with local RF transmission regulations before deployment. Check for moisture sensitivity handling requirements during storage and assembly processes.

RF Transmitter Selection Notes

Select this component for applications requiring compact FM transmission with integrated RDS encoding. Consider the 20-QFN package size for space-constrained designs. Verify interface compatibility with host controllers supporting I2C and I2S protocols. Evaluate power consumption against system battery life requirements.

RF Transmitter Part Context

This part belongs to the Si4712/13-B30 series of FM radio transmitters. It shares functional similarities with the SI4713-B30-GM but lacks specific RDS/RBDS encoding features found in the latter. The series is designed for low external component count and high integration levels.
