2.1.1
Two differential inputs (MIP1/MIN1 and MIP2/MIN2) and one single-ended input (Ml3)
are connected to the amplifier AMI via an analog input multiplexer. The programmable
amplifier AMI provides a coarse gain adjustment range. Fine gain adjustment is
performed in the digital domain via the programmable gain adjustment stage GX (see
signal processor section). This allows a perfect level adaptation to various types of
microphone transducers without loss in the signal to noise performance.
Fully differential output HOP/HON connects the amplifier AHO to a handset earpiece.
Differential output LSP/LSN is provided for use with a 50- loudspeaker. Up to 100 mW
(sine wave) of power can be delivered to the loudspeaker via the amplifier ALS. The
programmable amplifiers AHO and ALS provide a coarse gain adjustment range. Fine
gain adjustment is performed in the digital domain via the programmable adjustment
stage GR.
Two implemented AFE-configuration registers (ATCR & ARCR) provide a high flexibility
to accommodate an extensive set of user procedures and terminal attributes.
