Hi, As I understand it, you have some inquiries related to the RX word alignment pattern. For your information, when the 8b10b blocks are enabled, the pattern used in the RX word alignment is the 10b encoded pattern of the 8b input data to TX parallel input. For example, 0x17C is the 10b version of 0xBC. Therefore, at the TX parallel input, you will feed 0xBC. TX will encode this data into 0x17C and send it to the RX through serial link. Please let me know if there is any concern. Thank you.
