GENERAL DESCRIPTION
The SA55621 is available as a I2S controller(I2S master) or target(I2S slave) device. The controller generates SCLK and LRCLK for the target for data transmission. The high-resolution sigma-delta audio ADC converts analog signals to digital and transmits them to the host SOC via I2S or TDM serial data formats. The audio DAC converts the I2S or TDM serial data from the host SOC to analog outputs. An integrated analog direct path transmits the microphone input to the outputs with a high drive strength line driver. The SA55621 is available in a compact QFN4×4-24 package.
