Recently ADI has released a new ADC : AD6688 . When I use AD6688-3000EBZ with ADS7-V2EBZ, I can not to capture data from ACE on PC. And I have operate according to "EVALUATING THE AD6688 RF DIVERSITY and 1.2 GHz BANDWIDTH OBSERVATION RECEIVER". The SPI communication is successful and the PLL Locked indicator light is green. Soon afterwards I find the lights of S5 and S6 go off on ADS7-V2EBZ .Why? And how can I do?
