Scalable Advanced Background Receiver
- This page contains information on a product that is not recommended for new designs.
The TEF7016 and TEF7018 are analog single-chip radio background ICs specifically designed for background reception. Both devices support all major global background receiver standards such as Radio Data System (RDS), Radio Broadcast Data System (RBDS), Traffic Message Channel (TMC), DARC (VICS and RTIC) and optional support of digital radio via a co-processor (HD Radio and DRM).
The devices are following the industry-proven background receiver TEF7006 and TEF7007 with improved performance and feature set optimizing the total system costs. They are completing NXP Semiconductors Car Radio portfolio to provide an efficient, high performing application. The TEF701X are housed in a HVQFN32 package designed for two- and multi-layer PCB applications.
The radio receiver includes the AM/FM front-ends, tuning synthesizer, channel filtering, demodulation, weak signal processing, noise blanking in FM mode, RDS and DARC reception and optional FM multipath improvements.
The TEF7018 supports AM and FM, HD Radio and Digital Radio Mondiale (DRM30 and DRM+). The TEF7016 is an FM-only version and supports optionally the digital radio standards FM-HD Radio and DRM+. For both TEF7016 and TEF7018, these digital radio standards are supported when used with NXP Semiconductors’ digital radio coprocessors such as SAF356X and SAF360X.
Furthermore the TEF7018 provides the complete feature set including AM IF noise blanking, AM SoftMute on Modulation and the TEF701X provides digital audio output (mono) via I²S.

Target Applications
- The TEF701X is a background receiver that can be used for Radio Data System (RDS), Radio Broadcast Data System (RBDS), Traffic Message Channel (TMC) and background reception for automotive applications. DARC reception is also supported via the MPX output to VICS/RTIC decoders.
- When used together with the digital radio coprocessors SAF356X and SAF360X, digital radio standards background reception can be supported.
Part numbers include: TEF7016HN, TEF7018HN.
