PRINCIPLES OF OPERATION
microphone mute function
Transmit channel muting can be selected by setting MICMUTE high. Muting provides 80-dB attenuation of the
input microphone signal.
receive operation
earphone amplifier
The analog signal is routed to the earphone amplifier differential output (EAROUT or EAROUT+), which is
capable of driving a load as low as 8
. EAROUT is recommended to be used as a differential output.
earphone mute function
Receive channel muting can be selected by setting the EARMUTE terminal to high.
receive PCM data format
D Companded mode: 8 bits are received, the MSB first.
D Linear mode: 13 bits are received, the MSB first.
