410-191 (DIGILENT)

The 210-191 is a PmodI2S peripheral module that provides a D to A converter allowing for high quality stereo sound from a digital source. This module provides an easy interface for converting digital samples into an analog signal with a wide arrange of sample rates and a large dynamic range. The PmodI2S contains a Cirrus Logic CS4344 stereo D to A converter that supports all major audio data interface formats and allows 16bit to 24bits of audio data at standard audio sample rates, including 48KHz, 96KHz and 192KHz. The PmodI2S runs off a master clock (MCLK) input that can be set from 500KHz to 50MHz. Audio data is supplied to the serial data input (SDIN) where it is clocked in by an optional serial clock (SCLK). If the SCLK is left disserted, the CS4344 will automatically set the sample rate based on the MCLK and LRCK. Either way the LRCK will control which channel is currently being read by the CS4344.
