CLKE SCKO Output Enable
This bit is read/write.
Default value: 0
CLKE = 0 SCKO enabled (default)
CLKE = 1 SCKO disabled
The CLKE bit is used to enable or disable the system clock output pin, SCKO.
FLT Digital Filter Rolloff Control
This bit is read/write.
Default value: 0
FLT = 0 Sharp rolloff (default)
FLT = 1 Slow rolloff
The FLT bit allows the user to select the digital filter rolloff characteristics. The filter responses for
these selections are shown in the Typical Performance Curves section of this data sheet.
INZD Infinite Zero Detect Mute Control
This bit is read/write.
Default value: 0
INZD = 0 Infinite zero detect mute disabled (default)
INZD = 1 Infinite zero detect mute enabled
The INZD bit is used to enable or disable the zero detect mute function. Setting INZD = 1 allows the
analog outputs to be set to the bipolar zero level when the PCM1738 detects zero data for both left
and right channels for 1024 sampling periods (or LRCK cycles).
