How to interface EVAL - AD7768 with ADSP21569

We intend to use AD7768 8-channel ADC together with ADSP21569 DSP in our project. It seems as there isn’t a straightforward way of interfacing these two components. The DSP has many data transfer options (like SPI, OSPI, SPORT and LINK) with various modes but the ADC being a clock master (DCLK is an output on AD7768), none of these interfaces solves the problem. Although the LINK port uses input clock in receive mode, framing becomes an issue in this case.

Is there a way you may suggest, without using an FPGA as a glue chip, to interface these two components in order to get something around 8x64k samples/sec performance rate.

Thanking you in advance
