PRODUCT OVERVIEW
The PCM4202 is a high-performance, stereo audio
analog-to-digital (A/D) converter designed for use in
professional and broadcast audio applications. The
PCM4202 features 24-bit linear PCM or 1-bit Direct
Stream Digital (DSD) data output capability for both
channels. Sampling rates up to 216kHz are supported for
PCM output formats, while 64x or 128x oversampled 1-bit
data is supported for DSD output mode. Native support for
both PCM and DSD data formats makes the PCM4202
ideal for use in a wide variety of audio recording and
processing applications.
The PCM4202 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 data outputs, with a minimum stop band
attenuation of 100dB for all sampling modes.
The PCM output mode features clipping flag outputs for
each channel, as well as a digital high-pass filter for DC
removal. The PCM4202 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 PCM4202.
