The Pmod I2S 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. It is designed to work at standard audio rates, although the master clock can run anywhere from 512 kHz to 50 MHz.

Features:

• Stereo 24-bit D/A converter
• Output converted audio signals through standard headphone jack
• Supports all major audio data interface formats
• Accepts 16-24 bits of audio data
• Small PCB size for flexible designs 1.0 in × 0.8 in (2.5 cm × 2.0 cm)
• 6-pin Pmod connector with GPIO interface
