"The Audio Codec IP core is a complete high quality, low power audio codec for portable applications that includes the functions of Analog (A)-to-Digital (D) and D-to-A conversion, channel filtering, microphone, line and headset interfacing and signal mixing. Oversampling sigma-delta technology is used in both Record (ADC) and Playback (DAC) conversion channels. The channel filters are implemented digitally, embedded in the decimation and interpolation filters associated with the converters. Line in/out, Microphone and Headset Drivers are included offering a complete coverage of most common analog interfacing. Individual volume control schemes allow maximum flexibility on combining different record and playback functions. The Audio Codec IP operates a master or slave. The master clock can be 12 MHz, 24 MHz, 256 or 384 times the sampling frequency and the I2S Digital Audio Interface allows sampling rates from 8 to 192 kHz, including the popular 44.1 kHz, 48kHz and 192 kHz audio rates. External component requirements are extremely reduced as no separate microphone amplifier, microphone bias, headphone driver or references are required."
