SAF7741HV processor

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

Features

1.  The STK4102II series (THD=0.4%), STK4201V series (THD=0.08%) and STK4141X series THD=0.02%) are pin-compatible. Once the PCB pattern is designed, you can easily satisfy the repuirements for new sets simply by changing the IC.

2. Built-in muting circuit to cut off various kinds of pop noise.

3. Greatly reduced heat sink due to substrate temperature 125°C guaranteed.

4. Current mirror circuit application reduces distortion to 0.08%.
