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 published
ADSP-BF522/ADSP-BF523/ADSP-BF524/ADSPBF525/
ADSP-BF526/ADSP-BF527 datasheet for general
description and specifications. This document only describes
the differences from that data sheet.
The ADSP-BF522C/523C/524C/525C/526C/527C adds a low
power, high quality stereo audio codec for portable digital audio
applications with one set of stereo programmable gain amplifier
(PGA) line inputs and one monaural microphone input. It features
two 24-bit analog-to-digital converter (ADC) channels
and two 24-bit digital-to-analog (DAC) converter channels.
The CODEC can operate as a master or a slave. It supports various
master clock frequencies, including 12 MHz or 24 MHz for
USB devices; standard 256 × fS or 384 × fS based rates, such as
12.288 MHz and 24.576 MHz; and many common audio sampling
rates, 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.
