Section 26 Sampling Rate Converter (SRC)
Section 26 Sampling Rate Converter (SRC)
The sampling rate converter (SRC) converts the sampling rate for data produced by decoders such
as WMA, MP3, or AAC.
26.1 Features
• Data size: 16 bits (stereo/monaural)
• Sampling rates
Input: Either 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, or 48
kHz is selectable.
Output: Either 32 kHz, 44.1 kHz or 48 kHz is selectable.
• Processing capacity: A maximum of 10 µs sample output interval (Pch = 54 MHz)
• SNR: 93 db or higher
• Three interrupt sources: Input data FIFO empty, output data FIFO full, and output data FIFO
overwrite
• Two DMA transfer sources: Input data FIFO empty and output data FIFO full
• Module standby mode
Power consumption can be reduced by stopping clock supply to the SRC when not used.
