Audio Processor Advance Information
DS4289 ISSUE 4.1 January 2001
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 and SAT filters, deviation setting amplifiers for 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. ACE9040 combines minimum power consumption with low external component count. Standby modes greatly reduce supply current and extend battery charge intervals.
