DESCRIPTION
The PCM4204 is a high-performance, four-channel
analog-to-digital (A/D) converter designed for professional
and broadcast audio applications. The PCM4204
architecture utilizes a 1-bit delta-sigma modulator per
channel incorporating a novel density modulated dither
scheme for improved dynamic performance.
The PCM4204 supports 24-bit linear PCM output data,
with sampling frequencies up to 216kHz. The PCM4204
can also be configured to output either 64x or 128x
oversampled, 1-bit direct stream digital (DSD) data for
each channel. In addition, the PCM4204 supports a DSD
input mode, allowing 1-bit DSD to 24-bit PCM data format
conversion utilizing the on-chip digital decimation filter.
These features make the PCM4204 suitable for a variety
of digital audio recording and processing applications.
The PCM4204 includes a flexible audio serial port inter-
face, which supports standard PCM audio data formats, as
well as time division multiplexed (TDM) PCM data formats.
Multiple format support allows the system designer to
choose the interface format that best suits the end applica-
tion. Audio data format selection, sampling mode configu-
ration, and high-pass filter functions are all programmed
using dedicated control pins.
The PCM4204 operates from a +5V analog power
supply and a +3.3V digital power supply. The digital I/O
pins are compatible with +3.3V logic families. The
PCM4204 is available in a thermally-enhanced HTQFP-64
PowerPAD
package.
