Audio Input Section
Microphone Bias
Two microphone bias circuits are provided. One circuit supplies up to two handset microphones via the
two outputs MC1RB and MC1LB. The second circuit supplies the headset microphone via MC2B. The
microphone bias resistors of 2.2 kOhm are included. The bias circuits can be enabled and disabled.
The bias MC2B includes a microphone detect circuit which monitors the current flow through the output
both when the bias is disabled or enabled. This will generate an interrupt to the processor. In this way the
attach and removal of a headset microphone is detected. Also it allows to include a send/end series switch
with the microphone for signaling purposes. When the output of the MC2B gets out of regulation, an
interrupt is generated. This allows for connecting a switch in parallel to the microphone.

Microphone Amplifiers
Figure 8 on page 31 shows a block diagram of the microphone amplifier section. A selection can be made
between one of the three amplified inputs: the handset microphone connected to MC1RIN, the headset
microphone connected to MC2IN, and the line input TXIN. The selected channel can be fed into the
receive channel for test purposes. In addition a second amplified input channel can be selected for the
second handset microphone connected to MC1LIN. The gain towards to voice CODEC can be
programmed in 1 dB steps from –8 dB to +23 dB.
In addition to the microphone amplifier paths, there is also the possibility to route the stereo line in signal
from RXINR and RXINL to the voice CODEC dual ADC section. This allows for 13-bit, 16 kHz sampled
stereo recording of an analog source such as FM radio.
