ADSP-2103 or ADSP-2105 is the digital signal processor produced by ADI. The interface circuit between AD7714 and ADSP-2103/2105 is shown as the chart. If ADSP-2103/2105 RFS non-end and TES non- end are configured as low level, the output is effective, then SCLK end is configured as serial clock output. The AD7714 's POL termination is connected to low level. In order to ensure that the AD7714 can work normally, ADSP-2103/2105 serial clock frequency should be limited to less than 3MHz.
