This document describes the differences between the ADSPBF522C/523C/524C/525C/526C/527C and the ADSP-BF522/ADSP-BF523/ ADSP-BF524/ ADSP-BF525/ ADSP-BF526/ADSP-BF527 standard product. Please refer to the publishedADSP-BF522/ADSP-BF523/ADSP-BF524/ADSPBF525/ADSP-BF526/ADSP-BF527 datasheet for generaldescripTIon and specificaTIons. This document only describesthe differences from that data sheet.The ADSP-BF522C/523C/524C/525C/526C/527C adds a lowpower, high quality stereo audio codec for portable digital audioapplicaTIons with one set of stereo programmable gain amplifier(PGA) line inputs and one monaural microphone input. It featurestwo 24-bit analog-to-digital converter (ADC) channelsand two 24-bit digital-to-analog (DAC) converter channels.The CODEC can operate as a master or a slave. It supports variousmaster clock frequencies, including 12 MHz or 24 MHz forUSB devices; standard 256 × fS or 384 × fS based rates, such as12.288 MHz and 24.576 MHz; and many common audio samplingrates, such as 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz, 32 kHz,24 kHz, 22.05 kHz, 16 kHz, 12 kHz, 11.025 kHz, and 8 kHz.
