AUDIO EFFECT PROCESSOR
S5A1901H02
PRODUCT OVERVIEW
OVERVIEW
The S5A1901H02, Audio Effect Processor, reproduces vivid sound of
certain places and dynamic sound of movies. The S5A1901H02 has
over 15 sound effect modes including two kinds of Karaoke mode. In
addition to the sound modes, the S5A1901H02 provides mic-echo,
vocal canceller, loudness function, graphic equalizer, spectrum ana-
lyzer interface, tone control and volume/balance control so that it can
satisfy various sound requirements of audio systems including TV,
stereo audio systems, etc. Furthermore, the S5A1901H02 has built-in
16 bit stereo Σ−∆ ADC and DAC for easy application. The
S5A1901H02 also includes two digital source interface blocks and a
host interface block supporting normal microcontroller and I2C bus
interfaces.

Codec Interface
The S5A1901H02 has on chip 16 bit stereo ADC and DAC with digital filters and serial interfaces to provide CD
quality sound for audio application. The digital A/D decimation filter takes in the encoded signals from Σ−∆ A/D
modulator, and outputs 16 bit stereo digital audio data through the serial interface. The D/A interpolation filter takes
16 bit stereo audio data from the serial interface, and outputs one bit signal to the Σ−∆ D/A. The oversampling rate
of the digital filter is 128xFs, where Fs can be varied from 4kHz to 48kHz and can be changed on the fly. The serial
data interface is running at 32xFs and supports both right justified format and I2S data format. To set input and out-
put formats of codec, see Table and Table .
Digital Source Interface Unit 1 (DSIU1)
The DSIU1 has a digital serial data input source (DSDI1) and a digital serial data output source (DSDO1). It sup-
ports 16/18/20/24 bit data length, and supports right justified, left justified or I2S format in data position. The format
of DSIU1 is controlled by a microcontroller through Host Interface Unit (HIU) and Configuration Register Unit (CRU)
as in Table 19 and Table . In formats of DSDI1 and DSDO1, only 16 bit data length is supported when the data rate
is 32xFs. The DSDO1 can operate either in slave or master mode while DSDI1 operates only in slave mode by
Configuration Register Unit (CRU) setting. Note that the MSB is transferred first.
