PRODUCT OVERVIEW
The PCM4204 is a high-performance, four-channel audio
analog-to-digital (A/D) converter designed for use in
professional and broadcast audio applications. The
PCM4204 features 24-bit linear PCM data outputs, as well
as 1-bit Direct Stream Digital (DSD) data output and input
capability for all four channels. Sampling rates up to
216kHz are supported for PCM output formats, while 64x
or 128x oversampled 1-bit data is supported for DSD
modes. Native support for both PCM and DSD data
formats makes the PCM4204 ideal for use in a wide variety
of audio recording and processing applications.
The PCM4204 features 1-bit delta sigma modulators
employing density modulated dither for improved dynamic
performance. Differential voltage inputs are utilized for the
modulators, providing excellent common-mode rejection.
On-chip voltage references are provided for the
modulators, in addition to generating DC common-mode
bias voltage outputs for use with external input circuitry.
Linear phase digital decimation filtering is provided for the
24-bit PCM output, with a minimum stop band attenuation
of 100dB for all sampling modes.
The PCM output mode features clipping flag outputs for
each of the four channels, as well as a digital high-pass
filter for DC removal. The PCM4204 may be configured
using dedicated input pins for sampling mode and audio
data format selection, high-pass filter enable/disable, and
reset/power-down operation.
A +5V power supply is required for the analog section of
the device, while a +3.3V power supply is required for the
digital circuitry. Figure 1 shows the functional block
diagram for the PCM4204.
