Mute
The AD1892 offers two methods of muting the digital audio
output. There is an external mute input (MUTE, Pin 27) that
“hardware” mutes the AD1892 digital audio output when
asserted HI. This input should be LO for normal operation. The
AD1892 digital audio output can also be “software” muted
through a write to Control Register 1, position D7. Writing a 1
mutes the digital audio output; writing a 0 (default) unmutes
the output.
The AD1892 mutes the digital audio output automatically when
the digital audio receiver is not locked to the incoming biphase
mark encoded stream, or when no biphase-mark signal is ap-
plied to the input of the AD1892 (i.e., NOSIG = 1). When
NOSIG is deasserted (LO), the digital audio output from the
AD1892 is immediately unmuted. The AD1892 automatically
repeats the last valid sample when a parity error or validity error
is encountered.
APPLICATIONS CIRCUITS
A typical microcontroller-oriented application circuit for the
AD1892 is shown in Figure 33.
A typical stand-alone application circuit for the AD1892 is
shown in Figure 34.
