Audio Application Examples
The QF1D512 Simple and versatie FIR engine (SavFIRe™) can be used in a number of audio applications, including stereo/multichannel, equalizers, crossovers, wireless headphones and wireless speakers.
The following block diagram illustrates the connection options to the QF1D512:
In this configuration, the QF1D512 accepts serial digital data through the SPI or I2S interface directly, or through the SPI interface after S/P-DIF conversion.
The QF1D512 enables precision digital filtering without a dedicated computing resource. The system microcontroller is sufficient to load the configuration or filtered data.
