Advance Information

Supersedes January 1997 edition, DS4289 - 2.5

DS4289 - 3.1 December 1997

ACE9040 provides all the speech signal processing and

data/SAT tone filtering needed for AMPS or TACS analog

cellular telephones.

Transmit voice channel functions comprise a microphone

amplifier, soft limiter, bandpass filter, compressor, hard

limiter, lowpass filter and a gain controlled amplifier to set

deviation level. Additional transmit circuits include a DTMF

generator,data andSATfilters,deviationsettingamplifiersfor

data/ST and SAT and a modulation combiner.

ACE9040’s receive path comprises a bandpass filter,

expander, volume control and power amplifiers to directly

drive an earpiece or handsfree transducer.

Gain settings, mute switches and filter characteristics are

programmed via a three wire serial interface.

To implement a handsfree function, both transmit and

receive paths have rectifiers for signal amplitude monitoring

via an external pin and signal path attenuators controlled via

the serial interface.
