Digital interface board
Two-way SPDIF I2S Analog PCM9211
This digital interface module offers a bidirectional system between SPDIF (coaxial and optical) and I2S. The card also provides an analog input. Thanks to its selector, it is possible to change the direction of the transmission. Thus, it is possible to enter in coaxial to exit in I2S and optical, to enter in I2S to exit in coaxial and optical and finally to enter in analog to exit in I2S, coaxial and optical. The module also allows to add a USB to I2S interface (sold separately).
This digital interface benefits from a quality design, including a filtered power supply, a PCM9211 digital transceiver chip, a bi-directional isolation buffer using a TI SN74HC245 chip and a SiTime A020R clock for low jitter.
