Flexible peripheral modules for all your designs

Pmod™ devices are Digilent’s line of small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and embedded control boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective - near sensors and actuators.

Pmod modules communicate with system boards using 6, 8, or 12-pin connectors that can carry multiple digital control signals, including SPI and other serial protocols. Pmod modules allow for more effective designs by routing analog signals and power supplies only where they are needed, and away from digital controller boards.

Overview Pmod I2S2

The Digilent Pmod I2S2 features a Cirrus CS5343 Multi-Bit Audio A/D Converter and a Cirrus CS4344 Stereo D/A Converter, each connected to 3.5mm 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 108KHz.
