NXP TEF810X 77GHz Radar Transceiver Sourcing
1 resources tagged with "Tef810x"
The NXP TEF810X is a single-chip 77GHz RFCMOS radar transceiver with 3 transmit and 4 receive channels, typically paired with an S32R MCU for ADAS and industrial sensing designs. When sourcing it through China, the device is hard to buy outside of authorized NXP distribution, so most listings you see on B2B marketplaces are either grey-market, recycled, or reballed parts. Genuine AEC-Q100 automotive-grade stock usually carries 26–52 week lead times and minimum reel quantities, so verify the supply path before committing.
In practice, sourcing the TEF810X means confirming the part is new and authorized — we check date codes, lot traceability, and ask for distributor invoice trails, since counterfeit and refurbished 77GHz transceivers are common on open-market channels.

FAQ
Can I buy genuine NXP TEF810X chips from Chinese suppliers?
Some Chinese brokers stock it, but the TEF810X is a controlled automotive part, so much of the open-market supply is grey-market or recycled. Insist on traceability back to an NXP-authorized distributor and verify date codes.
What MCU pairs with the TEF810X?
It is designed to pair with NXP's S32R radar microcontroller family (S32R27/S32R45), which handles the radar signal processing. Most reference designs assume this companion chip.
How do I avoid counterfeit 77GHz radar transceivers?
Request lot codes and a distributor invoice trail, and budget for incoming inspection or X-ray/decap testing on first lots. Reballed and remarked RF parts are a known problem in this segment.
