PRODUCTION DATA.
The descrambler is a 16-bit parallel self-synchronous descrambler based on the polynomial 1 + x14 + x15. From the JESD204B specification, the scrambling/descrambling process only occurs on the user data, not on the code group synchronization or the ILA sequence. Each multi-DUC has a separate descrambler that can be enabled independently. The descrambler is enabled by field SCR in the multi-DUC paged register JESD_N_HD_SCR (8.5.49).
