2. AMPS/TACS MODEM AND SAT CONTROLLER

General Description

The Modem function supports both AMPS and TACS mobile

phone systems. Selection is made via software; no external

component changes are necessary. The Modem provides the

following hardware:

CPU interface

Data Receiver

Data Transmitter

SAT Decoder

SAT Transmitter

The Data Receiver contains a Digital Discriminator, Data

Decoder and Word Sync Detector (see Fig. 20). The Transmitter

generatesManchesterencodeddata.TheSATreceivermeasures

the incoming SAT signal. The SAT transmitter can either re-

transmit the received SAT or generate one of the 3 standard SAT

tones .

External Pins

AFC/RXDATA Data Input (pin 60)

Data is fed into the digital Discriminator via this input pin. The

data can be a composite Voice, Data and SAT modulated carrier

mixed down to either 54kHz or 450 kHz. The signal must be of

the CMOS input levels described in the AC Characteristics

section. The ACE9030 provides such an output on its AFCOUT

pin. The ACE9030 samples the 450kHz IF with a 504kHz

clocked register to produce a 54kHz CMOS output.

TXDATA Transmit Data Output (pin 63)

When enabled this output generates Manchester encoded

Data at the appropriate data rate. This produces a digital output

which must be filtered and combined with the other sources of TX

modulation. The ACE9040 provides these functions via the DATI

input.

RXSAT Received SAT Input (pin 51)

This input is for the received SAT which, must have been

filtered to give the appropriate SAT tone with CMOS level

swings. The ACE9040 provides the filtering and amplification to

provide a suitable signal on the RSO output.

TXSAT Transmit SAT output (pin 62)

This output provides a CMOS level SAT frequency output.

The source can either be the Received SAT, or a totally

independent SAT tone generated locally in the ACE9050. This

output which must be filtered and combined with the other source

of TX modulation. The ACE9040 provides these functions via the

TSI input.
