SAF775CHN/N208W/BK

Digital Signal Processor Dsp Overview

The SAF775CHN/N208W/BK is an audio DSP from NXP Semiconductors, part of the SAF775x series. It features a dedicated E7a DSP providing over 700MHz for wireless processing and over 450MHz for audio processing. The device integrates two high-sensitivity on-chip tuners and supports digital broadcasts including HD, DAB, and DRM. It utilizes RFCMOS technology and is housed in an HLQFP-176 package. The unit includes integrated core audio processing functions and flexible audio routing for multiple inputs and outputs.

Digital Signal Processor Dsp Feature Summary

• Dual high-sensitivity on-chip tuners with AM/FM PACS and CEQ
• Advanced audio post-processing including PEQ, GEQ, delay lines, and compressors
• Support for digital radio standards such as HD Radio, DAB, and DRM
• Rich interface options including ADC/DAC, I²S, TDM, BBI2S, I²C, SPI, and S/PDIF

Digital Signal Processor Dsp Applications

• Mid-range vehicle entertainment head units
• High-end vehicle entertainment head units
• Digital radio receivers

Digital Signal Processor Dsp Procurement Notes

Verify availability status directly with authorized distributors or the manufacturer, as supply conditions may be restricted. Confirm the specific ROM code version N208 matches design requirements. Ensure ECAD models are compatible with the target PCB design tools before finalizing procurement decisions.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring integrated dual-tuner capabilities and advanced HiFi 2 audio processing. Compare against SAF7754 and SAF7755 variants to determine if specific tuner paths or feature sets like DAB support are necessary. Verify that the HLQFP-176 package fits the mechanical constraints of the host system.

Digital Signal Processor Dsp Part Context

This part belongs to the SAF775x family of automotive audio DSPs. Other members include SAF7754HV and SAF7755HV. These devices share the same core architecture but differ in tuner configurations and supported broadcast formats. The SAF775CHN variant specifically targets systems needing robust AM/FM performance with optional digital radio integration.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include SAF7754 and SAF7755 models. Selection depends on whether DAB tuning is required, as some variants lack the second tuner path for DAB. Verify pin compatibility and software configuration differences when migrating between these specific model numbers.
