DESCRIPTION
The SA5753 is a high performance low power CMOS audio signal
processing system especially designed to meet the requirements for
small size and low voltage operation of hand-held equipment. The
SA5753 subsystem includes complementary transmit/receive voice
band (300-3000Hz), switched capacitor bandpass filters with
pre-emphasis and de-emphasis respectively, a transmit low pass
filter, peak deviation limiter for transmit, digitally controlled
attenuators for signal level and volume control, audio path mute
switches, a programmable DTMF generator, power-down circuitry
for low current standby, power-on reset capability, and an I
2
C
interface. When the SA5753 is used with an SA5752 (companding
function), the complete audio processing system of an AMPS,
TACS, NAMPS or NTACS cellular telephone is easily implemented.
The system also meets the requirements of the proposed NAMPS or
NTACS specification, and can be used in cordless telephone
applications.
The SA5753 can be operated without the I
2
C bus interface by
pulling DFT (Pin 13) HIGH.
BENEFITS
Very compact application
Long battery life in portable equipment
Complete cellular audio function with the SA5752
