when LRCIN is in a “HIGH” phase and right channel data
is assumed when LRCIN is in a “LOW” phase. When bit
1 is “HIGH”, the polarity assumption is reversed.
Bit 2 (ATC) is used for controlling the attenuator. When
bit 2 is “HIGH”, the attenuation data loaded in program
Register 0 is used for both left and right channels. When
bit 2 is “LOW”, the attenuation data for each register is
applied separately to left and right channels.
Bits 4 (DSR0) and 5 (DSR1) are used to control multiples
of the sampling rate:
Bits 6 (SF0) and 7 (SF1) are used to select the sampling
frequency:

Bit 8 is used to control the infinite zero detection function
(IZD).
When IZD is “LOW”, the zero detect circuit is off. Under
this condition, no automatic muting will occur if the input
is continuously zero. When IZD is “HIGH”, the zero detect
feature is enabled. If the input data is continuously zero for
65, 536 cycles of BCKIN, the output will be immediately
forced to a bipolar zero state (V
CC
/2). The zero detection
feature is used to avoid noise which may occur when the
input is DC. When the output is forced to bipolar zero,
there may be an audible click. PCM1727 allows the zero
detect feature to be disabled so the user can implement an
external muting circuit.
