Hi, we want interface an adsp-sc584 with an ad7134, the ad1734 doesn't have i2s interface and it is not clear to us if it can interface with the dsp and possibly in what way.

Thanks in advance

Hi,

The AD7134 has a 4-wire SPI interface that is compatible with QSPI, MICROWIRE , and DSPs. Using the SPI interface, the user can access the ADC register map and control the AD7134. The AD7134 digital interface consists of two independent parts: an SPI interface for register access and device configuration, and a data interface for sending out conversion data. Meanwhile the ADSP SC584 supports communication with multiple SPI-compatible devices For more details i would suggest you to refer the AD7134 datasheet SPI Interface section Page No 58/86 .
