GENERAL DESCRIPTION
This document describes the differences between the
ADSP-BF52xC and the ADSP-BF52x standard Blackfin
prod-
uct. Please refer to the published ADSP-BF52x data sheet for
general description and specifications. This document only
describes the differences from that data sheet.
The ADSP-BF52xC processors add 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 sam-
pling 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.
The codec can operate at power supplies as low as 1.8 V for the
analog circuitry and as low as 1.8 V for the digital circuitry. The
maximum voltage supply is 3.6 V for all supplies.
The codec software-programmable stereo output options
provide the programmer with many application possibilities
because the device can be used as a headphone driver or as a
speaker driver. Its volume control functions provide a large
range of gain control of the audio signal.
CODEC DESCRIPTION
The ADSP-BF52xC codec contains a central clock source, called
the codec master clock (CODEC_MCLK) that produces a refer-
ence clock for all internal audio data processing and synch-
ronization. When using an external clock source to drive the
CODEC_MCLK pin, care should be taken to select a clock
source with less than 50 ps of jitter. Without careful generation
of the CODEC_MCLK signal, the digital audio quality
will suffer.
To enable the codec to generate the central reference clock
in a system, connect a crystal oscillator between the XTI/
CODEC_MCLK input pin and the XTO output pin.
