DESCRIPTION

The PCM2704/5/6/7 is TI’s single-chip USB stereo audio

DAC with USB 1.1 compliant full-speed protocol controller

and S/PDIF. The USB-protocol controller works with no

software code, but USB descriptors can be modified in

some parts (for example, vendor ID/product ID) through

the use

of an external ROM (PCM2704/6) SPI

(PCM2705/7) or on request.† The PCM2704/5/6/7

employs SpAct

 architecture, TI’s unique system that

recovers the audio clock from USB packet data. On-chip

analog PLLs with SpAct enable playback with low clock

jitter.

PRODUCTION DATA information is current as of publication date. Products

conform to specifications per the terms of Texas Instruments standard warranty.

Production processing does not necessarily include testing of all parameters.

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.

†The modification of the USB descriptor through external ROM or SPI must comply with USB-IF guidelines, and the vendor ID must be your own

ID as assigned by the USB-IF. The descriptor also can be modified by changing a mask; please contact your representative for details.
