DESCRIPTION
The PCM4222 is a high-performance, two-channel analog-to-digital (A/D) converter designed for use in
professional audio applications. Offering outstanding dynamic performance, the PCM4222 supports 24-bit linear
PCM, 1-bit Direct Stream Digital (DSD), and 6-bit modulator data outputs. The supported output formats make
the PCM4222 ideal for digital audio recording and processing applications. The multi-bit modulator output adds
versatility, allowing customers to design their own digital decimation filter and processing hardware. The on-chip,
linear phase decimation filtering engine supports Classic and Low Group Delay filter responses, allowing
optimization for either studio or live sound applications.

PCM4222
SBAS399A–OCTOBER 2006–REVISED MARCH 2007
The PCM4222 includes three PCM sampling modes, supporting output sampling rates from 8kHz to 216kHz.
The DSD output supports either 64x or 128x oversampled bit rates. The PCM4222 is configured using dedicated
control pins for selection of output modes, PCM audio data formats and word length, decimation filter response,
high-pass filter disable, and reset/power-down functions.
While providing uncompromising performance, the PCM4222 addresses power concerns with just over 300mW
typical total power dissipation, making the device suitable for multi-channel audio systems. The PCM4222 is
typically powered from a +4.0V analog supply and a +3.3V digital supply. The digital I/O is logic-level compatible
with common digital signal processors, digital interface transmitters, and programmable logic devices. The
PCM4222 is available in a TQFP-48 package, which is RoHS-compliant.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
