The xSRC is part of Dolphin digital audio IP & multi-channel ASRC family and can be used to interface various audio blocks operating at different sample rates. ( like between the DSP and Bluetooth)
This SRC allows sample rate conversion with high fidelity and low distorsion while guaranteeing the phase matching and data synchronisation of the output samples thanks to a specific digital processing.
This IP supports various standardized programmable Fs, master and slave modes and standard interfaces for control and data.
