SAF7741HV Dual IF car radio and audio DSP (N1F) Rev. 05 — 09 May 2008 Objective data sheet 1. General description The SAF7741HV is a combined Intermediate-Frequency (IF) car radio and audio Digital Signal Processor (DSP) with several powerful cores integrated onto a single device. It combines analog IF input, digital radio and audio processing, sample-rate converters and digital and analog audio output to enhance listening clarity and noise suppression while reducing multipath channel effect. The SAF7741 offers user-specific functions which can be configured to match the software platform required by the systems of individual car-radio manufacturers, thus providing a high level of product differentiation. It is equipped to work with the TEF7000 and TEF6730 integrated tuners for analog and digital AM/FM decoding and sound processing The SAF7741HV consists of two main processing blocks; one for radio and the other for audio. These blocks demodulate either the IF or the low-IF tuner o […]
