22.8.2018 Pmod I2S2 Reference Manual [Reference.Digilentinc]

https://reference.digilentinc.com/reference/pmod/pmodi2s2/reference-manual 1/9

The Digilent Pmod I2S2 (Revision A) features a Cirrus CS5343 Multi-Bit Audio A/D Converter

(https://reference.digilentinc.com/reference/pmod/pmodi2s2/reference-manual) and a Cirrus CS4344 Stereo D/A Converter

(https://www.cirrus.com/products/cs4344-45-48/), each connected to one of two audio jacks. These circuits allow a system board to

transmit and receive stereo audio signals via the I2S protocol. The Pmod I2S2 supports 24 bit resolution per channel at input sample

rates up to 108 kHz () and output sample rates up to 200 kHz ().

22.8.2018 Pmod I2S2 Reference Manual [Reference.Digilentinc] Functional Description The Pmod I2S2 utilizes a (Cirrus Logic CS4344 Stereo D/A () converter) to take digital audio data and output the corresponding analog signal through a standard stereo headphone jack (labeled Line Out). In addition, a (Cirrus Logic CS5343 Stereo A/D () converter) is used to convert analog audio signals from a second 3.5mm audio jack (labeled Line In) into digital audio data.
