The ADSP-2103 or the ADSP-2105 is designed as one kind of digital signal processor that is produced by the ADI company. The interface circuit of the AD7714 and the ADSP-2103/2105 are as shown in the figure. You can configurate the RFS and TES non-terminal of the ADSP-2103/2105 as the effective output port, and configurate the SCLK port as the serial clock output port. The POL port of the AD7714 is connected with the low level. In order to ensure the normal operation of the AD7714, the serial clock frequency of the ADSP-2103/2105 need to limit in the range of 0-3MHz.
