... For all Gain Blocks: All bits set maximum gain or attenuation FUNCTIONAL DESCRIPTION The SA5753 is an audio signal processor designed to meet the requirements of compact low voltage radio telephone equipment. It includes transmit and receive bandpass filters for voiceband (300-3000Hz) with pre-emphasis and de-emphasis respectively, a transmit peak deviation limiter, voice channel mute switches and a data path which can be summed into the transmit channel ...

... HPDN pin (Pin 6), which is an input in DEFAULT mode. When HPDN is pulled HIGH, the R6B2 bit is set to ‘0’ and the SA5753 is placed in it’s normal operating mode with all Gain Control Blocks set to 0dB except A3, which is set to –2dB. When HPDN is pulled LOW, the R6B2 bit is set to ‘1’ and the SA5753 enters POWER DOWN ...

... The control register bit map is shown below. Either a quick access or normal address mode can be used, determined by the two MSB bits in the first word following the SA5753 address word. If the quick access mode is used, the registers can be updated by sending only two bytes of information (address plus update are updated using the address mode, then B7 and B6 of the data word are ignored ...
