DESCRIPTION
The PCM4202 is a high-performance, stereo audio
analog-to-digital (A/D) converter designed for professional
and broadcast audio applications. The PCM4202
architecture utilizes a 1-bit delta-sigma modulator per
channel, incorporating a novel density modulated dither
scheme for improved dynamic performance.
The PCM4202 supports 24-bit linear PCM output data,
with sampling frequencies up to 216kHz. The PCM4202
can also be configured to output either 64x or 128x
oversampled, 1-bit direct stream digital (DSD) data for
each channel. Support for PCM and DSD output formats
makes the PCM4202 suitable for a variety of digital audio
recording and processing applications.
The PCM4202 includes a flexible audio serial port inter-
face, which supports standard audio data formats. Audio
data format selection, sampling mode configuration, and
high-pass filter functions are all programmed using dedi-
cated control pins.
The PCM4202 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 PCM4202 is
available in a small SSOP-28 package.

ELECTRICAL CHARACTERISTICS (continued)
All parameters are specified at TA = +25°C with VCC = +5V, VDD = +3.3V, and a measurement bandwidth from 20Hz to 20kHz, unless otherwise
noted. System clock frequency is equal to 256fS for Single and Dual Rate sampling modes, and 128fS for Quad Rate sampling mode.

(1) Applies to the RST input, pin 19.
(2) Single, Dual, and Quad Rate sampling modes are described within this data sheet.
(3) Dynamic performance parameters are measured using an Audio Precision System Two Cascade or Cascade Plus test system. The
measurement bandwidth is limited by using the Audio Precision 22Hz high-pass filter in combination with the Audio Precision 20kHz, fS/2, or
a user-defined 40kHz low-pass filter. All A-weighted measurements are performed using the Audio Precision A-weighting filter in combination
with the previously mentioned filters.
