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

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.
