SAF775DHN/N208WAMP

Digital Signal Processor Dsp Overview

The SAF775DHN/N208WAMP is an audio DSP from the NXP SAF775x series, designed for high-performance AM/FM/DAB dual-tuner applications in automotive infotainment systems. Built on RFCMOS technology, it integrates a dedicated E7a DSP providing over 700MHz of wireless processing and over 450MHz of audio processing capabilities. The device features two high-sensitivity on-chip tuners, integrated core audio processing functions, and flexible audio routing supporting multiple digital and analog inputs/outputs. It supports digital broadcasting standards including HD, DAB, and DRM.

• Advanced audio post-processing including PEQ, GEQ, delay lines, compressors, expanders, treble, and bass enhancement
• Rich interface support including ADC/DAC, I²S, TDM, BBI2S, I²C, SPI, and S/PDIF

Digital Signal Processor Dsp Applications

• Mid-range and high-end automotive entertainment head units
• AM/FM/DAB dual-tuner receiver modules
• Digital radio (HD/DAB/DRM) receivers

Digital Signal Processor Dsp Procurement Notes

Verify the exact suffix 'WAMP' against official NXP documentation, as standard listings often show 'WCMP' or 'WMP'. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for surface mount assembly. Check current supply status as availability may be restricted.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring simultaneous FM/HD and DAB tuning with advanced audio processing. Compare with SAF7754HN/N208WMP if only single tuner functionality is needed, or SAF7755HV variants for different package options. Ensure software activation codes are available for unlocking HiFi 2 kernel features.

Digital Signal Processor Dsp Part Context

This part belongs to the SAF775x family of car DSPs. Other members include SAF7751, SAF7754, and SAF7755, which vary in tuner paths and audio processing capabilities (e.g., HiFi 2 support). The N208 ROM code version indicates specific firmware configuration.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include SAF7754HN/N208WMP or SAF775DHV/N208Q/EY, depending on required tuner configurations and package type. Verify pin compatibility and software feature sets before substitution.
