SAF775CHN/N208Z/AK

Digital Signal Processor Dsp Overview

The SAF775CHN/N208Z/AK is an automotive audio DSP and radio tuner from the NXP SAF775x series, designed for mid-to-high-end vehicle infotainment systems. It integrates two high-sensitivity on-chip tuners supporting AM/FM and DAB digital broadcasting. The device features a dedicated E7a DSP core providing over 450MHz of audio processing capability, enabling advanced HiFi 2 audio post-processing functions such as parametric equalization, delay lines, and dynamic range compression. It supports flexible audio routing with multiple digital and analog interfaces, including I²S, TDM, S/PDIF, and ADC/DAC connections.

Digital Signal Processor Dsp Feature Summary

• Dual-tuner architecture supporting WB-AM/FM/HD Radio and DAB reception
• Integrated HiFi 2 audio DSP with >450MHz processing capacity
• Advanced audio post-processing: PEQ, GEQ, compressors, and bass enhancement
• Flexible multi-channel audio routing via I²S, TDM, S/PDIF, and analog I/O

Digital Signal Processor Dsp Applications

• Mid-range to premium automotive head units
• Software-defined car radio architectures
• Hybrid broadcast and IP-based infotainment systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'AK' against official NXP documentation, as standard listings often use suffixes like 'WBMP' or 'ZT'. Confirm package type (HLQFP-176) and ROM code version (N208). Check for moisture sensitivity classification and reflow soldering profile requirements during procurement planning.

Digital Signal Processor Dsp Selection Notes

Select this model when both AM/FM analog tuning and DAB digital reception are required in a single chip. The SAF775C variant typically includes the second tuner path for DAB, unlike lower-tier models. Ensure the design supports the HLQFP-176 package thermal and pin-out requirements. Verify software license activation codes if advanced HiFi 2 features are needed beyond the base ROM.

Digital Signal Processor Dsp Part Context

Part of the NXP SAF775x family of automotive audio processors. This series bridges standalone tuners and full system-on-chips, offering scalable performance through software-defined radio capabilities. It complements other NXP solutions like the SAF9000 and SAF360x by providing integrated DSP and dual-tuner functionality for complex audio environments.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the SAF775x family include SAF7751HN, SAF7754HN, and SAF7755HN, depending on whether DAB support is required. Verify pin compatibility and software configuration files before swapping. No public cross-reference data confirms direct pin-for-pin replacements outside the SAF775x series.
