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.
