DEVICE DESCRIPTION
ASYNCHRONOUS OPERATION
The PCM3060 supports complete asynchronous operation between the ADC and DAC by receiving two
independent system clocks on SCKI1 and SCKI2.
SYSTEM CLOCK
The PCM3060 requires two system clocks for operating the ADC and DAC blocks independently, or it requires
one common clock for synchronous ADC and DAC operation.

Also, the PCM3060 supports synchronous operation between ADC and DAC by receiving one common system
clock on either SCKI1 or SCKI2 and controlling the system clock configuration through register 67 or 72 in serial
mode control.
The system clock for the ADC of the PCM3060 must be 256, 384, 512, or 768 f
S
, where f
S
is the audio sampling
rate for the ADC, 16 to 96 kHz.
The system clock for the DAC of the PCM3060 must be 128, 192, 256, 384, 512, or 768 f
S
, where f
S
is the audio
sampling rate for the DAC, 16 to 192 kHz.
Table 2
lists the typical system clock frequencies, f
SCKI1
and f
SCKI2
for common audio sampling rates, and
Figure 21
shows the timing requirements for the system clock inputs.
