APPLICATIONS

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.
