AD9854 Interface with BF537 via Parallel Port.

Dear All,

I am planning to use AD9854 to interface it with ADRF6701 to generate RF SSB Output frequency in tune of 800-1000 MHz. Our application requires that the frequency to be changed in quick succession/fast frequency sweep with fix PLL frequency in ADRF6701.

For this, I would require to do fast 100 MHz parallel 8-bit programming. I am interfacing AD9854 with ADSP-BF537 Blackfin Processor. Can you please let me know from the example circuit how to interface AD9854 with ADSP-BF537? Quick reply will be highly appreciated.

The steps that would be followed is as below

BF537-AD9854-ADRF6701
