SA5753 General 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 I2C 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 I2C bus interface by pulling DFT (Pin 13) HIGH.
