# onsemi 0339-671-TLM-E: Sourcing an AM/FM Car Radio Tuner IC With Sparse Data The 0339-671-TLM-E is listed by ChipApex as an onsemi analog car radio tuner IC for AM and FM reception, supplied in bulk. Public parametric data is thin. That is typical of parts that came from Sanyo's automotive audio range after onsemi acquired it, many of which were sold to a few head-unit makers instead of through broad catalog channels. AM/FM tuner ICs of this generation usually integrate the front-end mixer, IF amplifiers, a detector and stereo decoding, with an external PLL or a microcontroller handling station selection. Designers replacing a failed unit in an existing radio mainly need pin and function compatibility, not new features. Because the data is limited, treat each purchase as a verification exercise. Ask for the original marking, the date code and the package photographs, and compare them with a known-good board. If possible, test a sample in the target radio before committing to quantity. Lifecycle is the other concern. Check onsemi's product change notices for last-time-buy announcements, and plan an alternative path for long-life service needs. Moving to a modern single-chip tuner usually requires a redesign rather than a drop-in swap. For repair shops and small manufacturers supporting legacy vehicle audio, a reliable independent source with traceable stock is often the only practical option.
