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.

Key Benefits

  • Phase alignement feature to guarantee output data samples synchronisation
  • Predictable latency shared by all channels
  • Configurable input sampling frequency among standardized Fs:8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48, 88.2, 96, 176.4, 192 kHz
  • Configurable output sampling frequency among standardized Fs:8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48, 88.2, 96, 176.4, 192 kHz
  • Slave and master modes supported independently on input and output interfaces
