TEF6687AHN/V205K: Is it still orderable, and worth it over the 6686? Hey everyone, Trying to source the TEF6687AHN/V205K for a small production batch and I'm a little lost on its status. The 6687 doesn't show up on nxp.com at all (only the 6686HN/AHN as active), but it's listed in PCN 202303021F01 from 2023, and Rochester has stock as an authorized EOL source. Is it still genuinely orderable, or basically EOL now? And is anyone else authorized carrying it. Ideally in Asia/HK, since shipping to HK has turned into a bit of a headache? I'm also curious whether the jump from the 6686 is really worth it. The datasheet lists FMSI and full-search RDS as the extras, but I can't find any real-world comparison. Do those actually make a noticeable difference in practice? And do they need the /V205 firmware, or just the 6687 die? Any pointers, or an app note comparing the two, would be hugely appreciated. Thanks a lot! RF Re: TEF6687AHN/V205K: Is it still orderable, and worth it over the 6686? Hello Julian Ghiglieri
Thanks for the questions
The status of TEF6687AHN/V205K is ACTIVE means orderable in our system,even though it cannot be found in our website.
For the the key difference, it is that the TEF6687 includes the FM Stereo Improvement (FMSI) algorithm, which maintains FM stereo audio at weaker RF input levels — the TEF6686 does not have this feature; the TEF6687 also includes full-search RDS.
Unfortunately, the TEF668XA datasheet (which covers the TEF6687AHN) is confidential and under NDA.
