Why is the SD-SDI rx_dataout incorrect when using software versions 12.1sp1 and later?


Due to a problem in Quartus® II software version 12.1sp1 and later, you may see the rx_dataout recovered incorrectly when receiving SD-SDI with a high jitter source. Both SDI® and SDI II IP Cores are affected.


To work around this problem when using software version 15.0 of the SDI II IP Core, download and install patch 0.19 from the links below.

The jitter tolerance for SDI and SDI II IP Cores is scheduled to be improved in a future release of the Quartus II software.
