Can the polynomial be changed for scrambling in Stratix 10 Native PHY-PCS?

[HBhat2]

Hi,

As per XCVR user guide, Stratix 10 Native PHY supports with scrambling with x58 + x39 +1 polynomial. I want the scrambling with G(X) = X^23 + X^21 + X^16 + X^8 + X^5 + X^2 + 1 polynomial. Is it possible to use the same PCS with scrambling support, but with a different polynomial in the Native PHY?

With regards,

HPB

Hie, My apologies but the polynomial for the PCS scrambler is fixed. Hence, you cannot change it. Regards, Nathan
