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

Description

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.
