DESCRIPTION
The PCM3060 is a low-cost, high-performance,
single-chip, 24-bit stereo audio codec with
single-ended analog inputs and differential analog
outputs.
The stereo 24-bit ADC employs a 64-times
delta-sigma modulator. It supports 16–96 kHz
sampling rates and a 16/24-bit digital audio output
word on the audio interface.
The stereo 24-bit DAC employs a 64- or 128-times
delta-sigma modulator. It supports 16–192 kHz
sampling rates and a 16/24-bit digital audio input
word on the audio interface.
The PCM3060 supports fully independent operation
of the sampling rate and audio interface for the ADC
and DAC.
Each audio interface supports I
2
S, left-justified, and
right-justified formats with 16/24-bit words.

SLAS533 – MARCH 2007
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.
DESCRIPTION (CONTINUED)
The PCM3060 can be software-controlled through a 3-wire SPI-compatible or 2-wire I
2
C-compatible serial
interface, which provides access to all functions including digital attenuation, soft mute, de-emphasis etc.
The PCM3060 can be also used in hardware mode, which provides three basic functions.
The PCM3060 is fabricated using a highly advanced CMOS process and is available in a small 28-pin TSSOP
package.
The PCM3060 is suitable for various sound processing applications for DVD-RW, digital TV, STB, and other AV
equipment.
