DESCRIPTION
The PCM2904/2906 is Texas Instruments single-chip
USB stereo audio codec with USB-compliant full-speed
protocol controller and S/PDIF (PCM2906 only). The
USB protocol controller works with no software code,
but the USB descriptors can be modified in some areas
(for example, vendor ID/product ID). The
PCM2904/2906 employs SpActarchitecture, TI’s
unique system that recovers the audio clock from USB
packet data. On-chip analog PLLs with SpAct enable
playback and record with low clock jitter and with
independent playback and record sampling rates.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments
semiconductor products and disclaimers thereto appears at the end of this data sheet.
(1)The descriptor can be modified by changing a mask.

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.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
