Dear Louijie, I heard about this issue with the AD9913 DDS. Could you confirm and expand on this? We have been having some intermittent problems with the DDS.
>>There is a well-known issue with the ADD9913 wherein the serial bus gets one bit off the message it's supposed to be receiving and then remains one bit off indefinitely. He said there was a dedicated pin on the IC which issues a command to clear the SPI input buffer so that it can get back in sync with the master.
Do you know which pin is being referred to? We assumed it was not the master reset pin. Thanks,
